Technical description
3.1.1
Machine control
The main machine control element consist in central touch screen display located on a turntable
console of the delivery. Most important functions of the machine can be controlled from this
place. Other control elements are positioned on the control panels of printing units and feeder.
They are used for direct control of functions of the respective part of the machine. The control
panels are easily accessible for the operator of the machine. Their face area with pushbuttons
is covered with a foil keyboard, which makes maintenance and cleaning of panels considerably
easier.
3.1.2
Operator safety
The machine is equipped with covers with safety protection.
Any opening covers nor tilting safety spacers, the machine
will be stopped automatically. Mechanically blocked STOP
buttons are located always within the reach of the operator.
The lockable main switch eliminates the possibility of
machine start by an unauthorized person. The places of
convergence of the printing rollers are protected with
swinging safety spacers that will stop the machine even in
case of a small deflection.
CE safety standard
Safety braking is ensured by a separately energized
independent brake with a dedicated relay safety module in
accordance with CSN EN 60204-1 standard.
All safety elements satisfy stringent safety regulations incl.
CE and GS standards.
GS safety standard
3.1.3
Printing unit stands
The assembled sides of the printing units, feeders and deliveries form separate units. They may
be disjointed (for transportation).

3.1.4
Machine drive
The drive of all printing rollers and inking unit rollers is derived from outside positioned angular
gearing. The gearing is automatically central lubricated. The main electric motor drives the
transfer roller on a given printing unit (in the middle of the machine, according to total number
of printing units) with a belt and gear transmission and with co-engaging gears of another
printing unit. The main electric motor is equipped with a separately energized independent
brake that will stop the machine in case of activation any safety element.
3.1.5
Feeder
The feeder guarantees proper sheet loading in the machine. The feeder head (described
separately below) is its most important part. The working height of the pile is controlled with the
feeder head caliper and can be adjusted by height setting of the complete feeder head. The
feeder is adapted for palettes. The palette is to be positioned behind the board (the palette
trolley can be approached using the wedge supplied). Side feed of the complete board with
palette can be used for correction of inaccuracies in sheet pile alignment.
3.1.6
Nonstop feeder
Nonstop feeder ensures continuous feeding without stopping
the machine after taking all sheets from the main feeding
palette. The machine is equipped with an auxiliary grate (with
independent drive) that carries the rest of the pile towards the
feeder head while the operator can add sheets to the pile and
add it to the fed one.
The grate consists of rods that are to be loaded in slots in the
pallet. The grate is carried on two girders driven with an
electric motor through chains. Feeding pallet for nonstop
feeder should be stacked onto standard pallet.
3.1.7
Feeding pallet for nonstop
delivery
Feeding head
The feeder head is equipped with two sets of suckers, i.e.
with four lifting and two transport ones. The lifting suckers
can be tilted in sides. The caliper is not provided with blowing
in pile function. A pair of stationary blowers perform the
function, providing longer time for better sheet separation.
The height of the transport suckers can be adjusted even
during machine operation.
The rotary valve that controls air distribution pressure and
vacuum modes can be removed from the feeder head body
Feeding head
easily and cleaned from deposited paper dust.
The working height of the table is bonded with the feeder
head height adjustment. Feeder head adjustment according
to paper size using an adjustable screw is easy and quick. The calliper is easy adjustable,
equipped with a contactless position sensor that allows reliable control of the feeder table
stroke in the range of production speed. Excessive movement of the feeder head caliper into
the paper pile can be compensated by adjusting pile height with respect to the lifting suckers of
the feeder head. This operation can be done using a rotary control element on the feeder head
during machine operation.

3.1.8
Ionization
The device eliminates paper static charge. It contributes to
more reliable transport of sheets in this way. Use of ionization
is suitable in particular for thin and recycled papers. The
device consists of two rods with high-voltage points (one in
the feeder and one in the delivery) and two nozzles blowing
ionized air in the pile from the feeder head. The device can
be activated on the feeder control panel. It automatically
stops if no paper transferred to the machine (to prevent
operator to be electrostatic discharge hit in contact with a bar
or a nozzle; although it is not dangerous, but unpleasant).
Ionization unit on the feeder head
3.1.9
Conveyor
The vacuum conveyor transports sheets from the feeder on
the face lays of the machine. It has its own air supply.
The drive is designed to reduce speed of the sheet
transported when it falls on the face lays, which limits
potential deformation of sheet front edge. There is a tilting
girder above the suction tapes on which two transport rollers
or rotary brushes delivered as machine accessories are
mounted.
Vacuum conveyor
3.1.10
Double sheet detection
The machine is equipped with ultrasound and mechanical
double sheet sensors as standard.
The ultrasound one indicates feeding more than one sheet
and requests no adjustment. In case of incorrect feed,
feeding and the obstruct sheets on feeding bar became is
stopped. There is a certain (small) group of printed materials
that are analyzed incorrectly with the sensor. E.g. some
recycled papers and expanded thicker papers that
incorporate air cells belong to this group. Juast these gaps
Double sheet ultrasound sensor
make even single sheet recognized as a double sheet. In
such case, turn the double sheet monitoring system off and
use an electro-mechanic device instead. This device should be adjusted according to the
thickness of the processed material (ref. Instruction Manual).
Electro-mechanic and ultrasound systems switching is
possible using the delivery touch screen.

3.1.11
Conveyor pressure pulleys for heavier materials
It is suitable to use special thrust wheels of a more robust
design for feeding. Wheels pressure is spring actuated. The
intensity is adjustable.
Thrust pulleys
3.1.12
Face lay
Sheets are transported on the bottom face lay that consists of a shaft with 8 stoppers. The shaft
with stops can be shifted in a small range in the printing direction and its right- and left-hand
parts can be deflected opposite to each other. This allows compensating minor face or diagonal
deflections when adjusting register.
All stops of the face lay are provided with a pulley that prevents in damage of the reverse side
of sheet when it is passing through the stops.
In the two stops of the face lay, there are optical barrier sensors for sheet detection on the face
lays and skewed sheets detection. Two pneumatic cylinders designated for safe catching and
blocking of the incorrectly loaded sheets so that they could not get in the first printing unit
operate in close cooperation with the system for sheet monitoring on the face lays.
3.1.13
Side lay
Side alignment of the loaded sheets is provided with two vacuum side lays - for each direction
of side aligning. Adjustment of positions of both side lays can be made on the attended side
using the handle. Side lay adjustment can be carried out even during machine operation. The
lay design itself allows using one or more suction chambers, which has effect on the the force
of sheet pulling. Thanks to slots in all channels, jamming with paper dust is eliminated.
3.1.14
Side lay operation monitoring device.
Each of two side lays is standard fitted with optical sensors
detecting sheet loading on the level of the side stop.
Incomplete sheet loading by about 0.3 mm (0.012") is
indicated with an acoustic signal prompting operator to adjust
the device. The device is not intended for measuring or
control of accuracy of side alignment but rather for inspection
whether the side lay has been adjusted properly by the
machine operator.

3.1.15
Pregripper
The machine is equipped with a lower swinging pregripper that will grip an aligned sheet when
at rest, then will accelerate it smoothly to the speed of the machine and hand it over in the
grippers of the subsequent transfer roller.
The pregripper is equipped with a device for pregripper grippers blocking in the open position.
This device prevents in gripping an incorrectly fed sheet with the grippers of the pregripper and
its subsequent transport in the machine.
As all the rollers with grippers, the pregripper uses stop boxes with special plastic filled grooves
on the surface filled with plastic. This allows precise sheet transport and eliminates paper dust
accumulation.
3.1.16
Dampening and inking unit rubber rollers
Dampening unit and inking units are fitted with Böttcher
rubber rollers. For rubber rollers washing we recommend
Böttcher or similar products; some suitable washing agents
are listed in the Operation Manual, see chapter 8.

3.1.17
Dampening unit
The dampening unit is a four-roller continual device with
dampening solution forced circulation and cooling. All rollers
are without any blanket. The inking and water pan rollers are
made with rubber coating, the metering roller is provided with
chromium plated surface finish while the bridge roller with
polyamide coated surface.
Engagement and disengagement of all dampening rollers is
fully automatic, pneumatic controlled depending the machine
mode . The speed of the water pan roller is derived from
controlled electric motors via machine control electronic Blanket-free dampening
system. The quick dampening pushbuttons are located on
control panels. The position of the bridge roller can also be switched over from the control panel
(possibility of connection of the dampening unit with the inking roller of the inking unit).

Dirt removal from printing plate - dampening differential drive
When printing on some types of paper that tend to dusting, dirt of variable character is released
from paper. This dirt mostly adheres to the printing plate and causes deterioration of printing.
Optional modified drive of dampening rollers is offered, which make slight speed difference
between the form roller and the dampening roller. In this way created relative movement (shear)
will remove all mechanical dirt from the printing plate very effectively. A slight increase of
dampening roller wear may occur within the mentioned option use, depending on setting of the
dampening unit rollers.

3.1.19
Inking unit
The inking unit consists of 19 rollers of which four are inking
rollers and four are distribution rollers. The drive of inking
unit rollers consists of angular gear wheels, which
considerably increase wheels engaging. This substantially
limits negative effect of the inking unit drive gear wheels on
printing quality.
Inking unit drive wheels
The distribution rollers are seated in sliding bushes. The
intensity of distribution can be adjusted to 0 to 30 mm (0-1.2“)
within the machine idle. The design of the drive of the
distribution rollers allows phase offset of distribution with
respect to the form roller periphery. This function can be used
for modification of colouring intensity in the direction of
printing.
Inking unit is equipped with hollow rollers and therefore can Distribution phasing with respect
be additionally equipped with inking unit temperature to the form roller
stabilization system.
The standard version of the machine is supplied with zone ink
ducts equipped with segmented blades. They allow very
precise ink supply to the inking unit according to consumption
from individual form parts. It improves the possibility of
colouring intensity control considerably. Optionally the
machine can be fitted with with ink duct cover (also available
for once shipped machines). This cover prevents in dirt falling
into ink in the ink duct. It is to be installed directly on the ink
duct body. The guard is tilting and easily removable without
use of tools.
Ductor surface is special low wear ceramic coated.
The drive of the ductors is provided with
independent electric motors and its speed is
controlled with the control system of the machine in
dependence upon machine speed and colouring
intensity setting.
To improve stability of the printing process or to
allow printing using water-free offset technology on
the machine, the inking unit can be provided with a
temperature control system.

Distribution
Optional inking roller axial movement mechanism is available. It allows achieving the required
printing quality in case of some expensive jobs. Distribution setting is comfortable without use
of tools after cover opening.
3.1.21
Inking unit with temperature control
The RAPIDA 75 machines can be provided with inking unit
cooling and heating system (a conditioned inking unit). This
device consists of three hollow distribution rollers in the
inking unit of each printing unit, coolant distribution system in
the machine and TECHNOTRANS cooling aggregate, type
alpha.c.
It is very advantageous to maintain constant temperature in
the inking unit when using standard offset printing with
dampening. Stable temperature contributes also to achieving Inking unit distribution rollers with temperature control
stable printing conditions. The operator can obtain the same
results at the beginning, in the course and in the end of the
job. Changes of ambient temperature will not affect the printing quality. The standard variant of
the inking unit is ready for installation of the temperature control system by using the hollow
rollers. Even once shipped machines can be temperature control completed. Steel rollers are
rust protected by additive in the cooling solution.
3.1.22
alpha.c
alpha.c is designed to allow temperature control of inking unit to
be independent of dampening solution dosing in the dampening
unit. Its compact design reduces necessary space. In case that
the machine is equipped with the inking unit with temperature
control, an independent unit is not used for dampening solution
circulation, but the dampening solution circuit is connected to the
TECHNOTRANS common aggregate. Cold air intake on the front
and upper heated air outlet allow device to be wall installed.
Optionally available is a pipe reducer to the print shop exhausting
system
TECHNOTRANS combined cooling
device
The device operates very reliably and with high precision of the
controlled temperature. IPA supply is fully automatic, adjustable in range of 0 to 15% and tank
refilled. Temperature of inking unit cooling medium is adjustable in range of 8 to 15 (46 to 59
°F). The aggregate allows continuous and fully automatic dampening medium tank refill. It is
possible to adjust mixing of supplied water and dampening agent that is supplied from a can.
Temperature of inking unit cooling medium can be adjusted within the range from 10 to 40°C
(50 to 104°F). Operation is carried out using a multi-language display. The device distributes
cooling power automatically according to current need. The price that is lower than in case of
two independent systems is the biggest advantage. When installing, it is necessary to provide
independent connection to the mains

Remotely controlled diagonal cocking
There are frequently cases when the motif has to be rotated during register adjustment. The
device for remotely controlled motif diagonal cocking positioned on the transfer roller allows
compensating machine register diagonal deviation during machine operation and even during
printing.
Principle of operation is as follows. The transfer roller flange is eccentric, turning it (using
the motor), the transfer roller axis deflection occurs, resulting in motif turning.
The total control range of the diagonal register on each printing unit is 0.12 mm (0.005“). Within
the operational range, the printing forms must be copied precisely. The required precision of
mutual position of the printing image with respect to the centring holes in the face direction must
be within tolerance of ±0.1mm (0.003“). Control of the diagonal cocking is possible from either
the ErgoTronic remote control desk touch screen display or from the delivery panel touch
screen display.
3.1.29
Printing plate semi-automatic loading
Printing form loading is one of the basic operations of press
preparation for printing. This means the form to the form roller
installation.
This operation consists of a number of sequential precisely
defined steps that have considerable effect upon preparation time
when changing printing jobs.
Printing form loading represents:
•
•
•
•
•
•
form inserting into the front clamping strip on registration pins
form gripping in the front bar
form winding up on the form roller with engagement of the
Printing plate
offset and form roller in pressure
semi-automatic loading
form end inserting in the rear clamping bar
form gripping in the rear bar
form stretching
In case of semi-automatic printing form loading, only the first of the steps listed above has to
18

Rapida 75
be carried out manually. The other steps are carried out automatically without operator's
intervention. Select the semi-automatic loading mode and the numbers of the printing units
where this operation will take place using the touch screen in the automatic loading menu. Then
operator can continue with the preselected printing units to load the form.
The procedure of printing form removal is also programmed semi-automatically in a similar way.
The device allows clamping both new and used printing forms with thickness of 0.2 to 0.3 mm
(0.008 to 0.012“).
Before clamping, the printing form rear edge is to be bent by the angle determined. Use delivery
included bending device to the purpose.
3.1.30
Offset rollers
The surface of the offset rollers is coated with a special
ceramic material. The offset blanket is fixed in stretching
bars which allows its quick replacement. The offset rollers
fixed with bars are used as standard. This design allows
perfect blanket stretching on the offset roller. A torque
wrench should be used to ensure proper stretching.
The offset rollers have rigid mounting in the disengaging
mechanism. Disengaging is carried out with a pneumatic
system with electric control. The rollers are disengaged
automatically or after depressing a pushbutton on the Printing pressure remote setting
control panel. Printing pressure setting (paper thickness)
takes place remotely using the touch screen on the delivery and can be carried out even while
the machine is running.
3.1.31

gripper holding force. Sheet alignment is carried out through
passage over an exhausted slot in the delivery. The system
consists of a pneumatically engaged vacuum chamber with a
slot and a blowing bar that pushes the sheet towards to slot.
The aligning function can be activated using the machine
touch screen. Sheet aligning is efficient for materials up to
abt. 150 g/m2.(39,9 Lbs bond)

Sheet guiding through machine
Sheet guiding through the machine is carried out mostly with chrome-plated sheets shaped
according to paper path, adjustable segments and with blowing in some places in order to
prevent in sheet damage.
There are smooth chrome-plated sheets over the pressure rollers in the standard variant; these
sheets together with standard chrome-plated guiding sheets on the transfer drums (see 3.1.33)
create the most suitable solution in order to prevent in damage of prints. The solution is
recommended for printing on all standard types of paper and paper with higher square weights.
Upon wish, it is possible to substitute smooth guiding sheets above the pressure rollers with
chrome-plated wires. The guiding wires are side adjustable and for that reason, they can be
positioned so as to guide sheet in its unprinted part. Moreover, this solution allows easier
access to the pressure roller e.g. during washing it. If the machine is equipped with guiding
wires over the pressure rollers, guiding sheets over the pressure rollers are not supplied.
3.1.41
Central lubrication
After achieving the specified machine speed programmed in the machine control system, the
lubrication system will deliver the required quantity of lubricant in the places where it is
necessary. Besides this, there are places on the machine which have to be lubricated in
intervals given by the Maintenance Manual or a lubrication schedule.
3.1.42
Air distribution system
The air distribution system provides main machine functions in the area of the feeder, delivery
and complementarily also in the printing units in the path of sheet passage. A dry rotary
compressor is a source of pressure and vacuum air in the feeder area.
Low-pressure blowers positioned under the delivery and controlled with frequency converters
from the delivery touch screen are used as a source of air in the delivery.
Pneumatic elements allow control of machine functions both with the automatic system and
machine control with pushbuttons from control panels and control screen.
The pneumatic circuit is driven by a dedicated compressor. The compressor is also available
as noise-damped.
As standard the machine comes with blowing hose useful eg. for machine maintenance and
cleaning.
If the printing shop is equipped with a compressed air central distribution system, the printing
press can be installed without this source, however, it should be provided with air regulation
and filtration system. Pressure in the pneumatic distribution system is 0.6 MPa (87 psi).

ErgoTronic remote control panel
ErgoTronic remote control system makes an integral part of
RAPIDA 75 machine.
ErgoTronic remote control panel
Standard type of ErgoTronic provides remote settings for ink
duct, colour ductor speed, register and water pan rollers
speed from the control panel. All information on the settings
mentioned above are displayed on the control panel screen.
The ErgoTronic control panel with viewing illumination is
used for storage and inspection of prints. The control panel is
position angle adjustable. The control panel also includes
two-position numerical displays for illustration of the current
position of each ink duct zone. The control panel is also
provided with USB connector. The machine setting data for
TECHKON densitometer
various printing jobs can be saved on a hard disk of the
ErgoTronic system computer or on USB Flash Disk. The
ErgoTronic system can be provided with TECHKON or Basic densitometers.
ErgoTronic with the densitometer, may serve as the
autodensitometer, which makes it ready to on-line connection to
the press. After densitometric measuring of the measuring strip
on a printed sheet, the measured values are compared
automatically with the values on the reference print or with
preselected values. In case that the measured values exceed
the tolerance set beforehand with respect to the reference
values, either automatic colour profile of ink ducts is reset
automatically or the operator of the press will confirm the
proposed correction of the colour profile of the ink ducts and
such correction is implemented subsequently. The objective of
the changes of the colour profile of ink ducts is achieving of
identical colouring of the printed and reference sheets.
The densitometer can be equipped with a polarization filter on
DENSITRONIC densitometer
the basis of an order. The polarization filter is used to suppress
the effect of gloss of blue colour - the device is sensitive to the
colour like if dry and enables to compare density values
measured on both dry and wet prints.
The values measured with the polarization filter and without it are different; the density with the
filter is always higher (by 0.2 - 0.3 D, not linear).
Measuring with densitometer without filter allows for the printer comparing and colouring sheets
currently even if ink is wet as measurement is carried out under the same initial conditions.
Moreover, measuring with the filter enables to compare densities even with "dry" print, e.g. with

CIP4 interface
CIP4 integration is an important element for improvement of quality of production together with
reduction of costs (Cooperation for Integration of Processes in Prepress, Press and Postpress).
CIP4 is a name of organization (www.cip4.org) established from a free association of
companies known as CIP3. CIP4 brings technology for automation of the printing job
processing management with emphasis upon interconnection of all production stages from
customer service up to shipment. KBA-Grafitec company is a member of the CIP4 organization;
PPF and JDF standards have been defined within CIP4.
PPF format (Print Production Format) is an international standard used for data description in
the process of printing job processing. PPF file contains detailed data on the job (such as job
name and author, customer, times and terms, previews of individual colour separations,
transfer functions, definitions of register marks and densitometric fields or data for finishing
operations). Most information enters the PPF file in the prepress stage, then data become
available for next production steps, reducing data entering repeatedly. The archived PPF files
can be used again in case of job repeating.
JDF (Job Definition Format) is a new universal standard independent of the platform and able
to interconnect various stages of the printing job production process and to it related operations
perfectly. It is based on experience and knowledge from already existing technologies
developed under the auspices of CIP4. In order to guarantee full compatibility, it includes also
PPF standards based on CIP3 and PJTF (Portable Job Ticket Format) by Adobe.
Using JDF, it is possible to describe a job from the first steps when it is discussed with the
customer up to packing and shipment to the customer. We meet also the term JMF (Job
Messaging Format) in association with JMF. JMF holds a function of a standard communication
language among various devices of your printing shop or between these devices and your MIS
Management Information System. The term MIS means an economic and planning system of
the printing shop. However, in order such interconnection could operate and we could utilize
the potential offered by JMF, it is necessary to use such devices and applications that
understand JMF messages and are able to receive and dispatch them and to respond them in
an adequate way. The MIS system generates so called job tickets (messages containing
working tasks) and sends them to the respective devices. Individual devices inform the MIS
system back on the current status of their task during working tasks (job tickets) processing.
The ErgoTronic system allows utilizing data in CIP4 formats for quick presetting of the printing
press for a printing job so that information on the printing job from a selected JDF/JMF or PPF
file (previews of individual colour separations, transfer functions, etc.) are processed with the
ErgoTronic system and subsequently used for presetting individual ink ducts and colour
ductors.
The ErgoTronic system allows in association with the standards defined by CIP4:
•
•
•
•
•
•
•
printing press presetting (ink ducts, ductors) on the basis of digital pre-press data
obtained from CIP4 technology
printing press setting using CIP4 technology for standard process colours (CMYK) as
well as special customer's colours
modification of presetting obtained from CIP4 data before proper setting of ink ducts
and ductors
machine presetting for printing both face and reverse sides according to CIP4 data
definition
automatic printing job centring
automatic trimming in case that preview exceeds printing area
printing press presetting according to factory predefined or user correction curves

•
easy loading a new correction curve with the name used in processed CIP4 data
•
creation and optimizing user correction curves on the basis of the data obtained

The ErgoTronic system can be incorporated into both a system using PPF files and JDF
workflow system:
1.
Integration of the GrafiControl system into workflow with PPF files
PPF files are complemented with previews of individual colour separations (or potentially
generated) simultaneously with data creating for the CTP system.
There are two ways to transfer PPF files into ErgoTronic system:
•
•
2.
online using the network (TCP/IP protocol)
using USB Flash disk
ErgoTronic system integration into simplified JDF workflow
The ErgoTronic system is incorporated in the local computer network together with the other
devices supporting JDF standard. RIP generates JDF ticket for the ErgoTronic system together
with creating data for CTP. The JDF ticket contains previews of individual colour separations
similarly like PPF file in the case described above. The ErgoTronic will receive the JDF ticket
pertaining to it and allow its processing. During printing job processing, the ErgoTronic system
enables to send reverse information on the status of the printing job in the JDF ticket generator.

ErgoTronic system integration into simplified JDF workflow
The ErgoTronic system is incorporated in the local computer network together with the other

ticket generator of the MIS system. The JDF ticket contains previews of individual colour
separations (similarly like PPF file). The ErgoTronic will receive the JDF ticket pertaining to it
and allow its processing. During printing job processing, the ErgoTronic system enables to send
reverse information on the status of the printing job in the JDF ticket generator.

Lacquering device
In accordance with the current trends in improving printed matters, a lacquering device for fullvalue powerful in-line lacquering has been developed. This device represents an option for the
machines of the RAPIDA 75 series and is designated for high-quality area and partial
lacquering with dispersion lacquer.
The benefits of the machine equipped with the lacquering unit consist above all in higher
efficiency of job processing. Powdering can be reduced to minimum. The job can be dispatched
for next processing almost immediately after printing and lacquering.
Resistance of the printed sheets against doubling and mechanical damage. The lacquered
sheets are considerably more resistant to water and the printed colours better resist to fading
out as a result of sunshine. Impressive visual and utility effects can be achieved by use of highly
gloss, pearl or metallic lacquers.
The device consists of the following parts:
•
•
•
•
lacquering unit; it is used to transfer uniform film of dispersion lacquer on the sheet
even at maximum printing speed
lacquer circulation system; its main function consists in providing lacquer supply in

3.2.3.1
Lacquering unit
The concept of the lacquering unit is based on the design of
the printing unit of the RAPIDA 75. Passage of sheet through
the lacquering unit - ie. design and arrangement of the
counterpressure roller and the transfer drum - is identical with
passage of sheet through the printing unit. General design of
the lacquering unit does not differ too much from the printing
unit.
Lacquering unit
Also lacquering roller position and diameter are
identical with the offset roller in the printing unit. The
diagram of the lacquering unit is shown below.
1) Transfer drum
2) Pressure roller
3) Raster roller
4) Chamber doctor
blade
The principle of the raster roller and the chamber ductor
blade system is used for lacquer dosing and creating a very
uniform lacquer film. Lacquer that is collected in raster roller
depressions circulates in the chamber doctor blade system.
Excessive lacquer is wiped from the raster roller with the
chamber doctor blade and is discharged back in the
circulation circuit. Lacquer that is collected in the raster roller
relief is transferred on the lacquering roller with pressure.
Finally, the uniform lacquer film is transferred onto printed
sheets by the counterpressure roller.
Lacquering unit - chamber doctor blade
system
Lacquer quantity transferred on paper is determined with raster roller raster density. A standard
printing shop specializing in a certain segment of printed matters will usually have 2 to 3 raster
rollers with different raster values. The raster value of the raster roller is stated using a number
that indicates number of lines per 1 cm (1 inch) of length. In case that raster roller relief is not
represented with depressions, but with a spiral micro-groove (Haschur), LR marking follows
after the number specifying the raster value. It applies generally that the rollers marked with LR
transfer higher quantity of lacquer at the same raster value and the lacquered surface has
better quality from the viewpoint of visual perception, however, such roller is a little bit more
expensive when compared with the roller with depressions. Common available rollers have
raster value ranging between 60 and 120 l/cm (152–305 l/inch).
Basic features of several raster rollers are listed in the table below. However, the values are
only approximate. They will differ between various manufacturers of raster rollers and depend,
among other, also on the type of lacquer used.

The standard variant of the lacquering unit is fitted with the raster roller with raster density of
100 l/cm (254 l/inch). Raster roller of this kind is to perform appropriate thickness lacquer
coating to avoid printed sheets deterioration.
Replacement of the raster roller in the lacquering unit represents an easy, manual and short
task for the machine operator. It is necessary to pay increased attention when handling the
raster roller. Its operational surface is hard, however simultaneously also very brittle. Any
damage of roller surface will be subsequently apparent on the lacquered area. The raster roller
weight parameter is then important from this viewpoint. The weight of the roller made of
aluminium alloy is approximately 25 kg (55.1 lb) and weight of steel roller is approximately 75
kg (165.3 lb). However, the aluminium alloy roller is approximately by 10 to 15% more
expensive.
The lacquering unit allows area or partial lacquering. Use of a lacquering blanket that is
clamped on the lacquering roller is the simplest and also the most cost effective alternative of
area lacquering. The area for lacquer transfer is to be created by lacquering blanket padding.
The pads are calibrated papers of the corresponding dimensions and thickness that are
mounted to the lacquering roller body in a simple way. For a precisely demarcated area or for
partial lacquering, is is suitable to use so called "stripping" blanket. This blanket is designated
for manual cutting or for machine cutting using a cutting plotter. The places that should not
transfer lacquer will be stripped manually after preliminary cutting. This will create lacquering
relief formed with height differentiated areas on the lacquering blanket. The lacquering blankets
are offered by all reputable suppliers of offset blankets.
In order to achieve register between the printed and lacquered images, the lacquering roller is
equipped with a device for fine adjustment of the axial and peripheral register within the range
of ±2mm (0.08“). This device can be used even if the machine is in operation and is controlled
manually. The surface of the lacquering roller can also be turned by 50 mm (2") in the direction
from collection edge. This operation is carried out manually and only in the machine is idle.

3.2.3.2
Lacquer circulation system
Chambered blade block adjacent to the raster roller during
lacquering operation is connected by hoses and electric cable to the
lacquer circulation pump and all the components make up the
lacquer circulation system, a product of Harris&Bruno (www.harrisbruno.com).
Lacquer applying on the raster roller is carried out by means of the
chamber doctor blade. Manual operation of the chamber doctor
blade is very simple and consists in mere blade tilting in order to dry
its internal space after washing or for the purpose of replacement of
sealing consumable material. It is necessary to pay increased
attention to wear of both blades and side sealing of the chamber
doctor blade. Printing speed with lacquering depends on many
factors, i.a. quantity of lacquer, ink, and dampening solution.
However, when maintaining optimum conditions, the result of
lacquering operation is not influenced with machine speed thanks to
the properties of the used concept of the chamber doctor blade.
Lacquer circulation pump
The circulation system features a number of automatic functions,
controlled by the machine operator in a comfort from a small touch
screen of the lacquer circulation pump control panel. These functions include:
•
•
•
•
•
•
•
Chambered blade engaging and disengaging to the raster roller
Circulation circuit filling with lacquer
Removal of residues of old lacquer and water from the circulation circuit
Lacquer circulation during lacquering operation
Monitoring of waste pan overfilling
Lacquer discharging from the circulation circuit
Washing of the complete circulation circuit including chambered blade using the
warm water
The complete system includes also a set of suction and discharging tubes that are positioned
in the tank with lacquer and in waste tank during lacquering unit operation. If the operational
mode of the lacquer circulation pump is changed (lacquering - discharging - washing), it is not
necessary to remove these tubes from the tanks. The lacquer circulation pump requires
compressed air supply for its operation. This supply is represented by a compressor that is
included in the delivery and is powered from the printing press itself. The compressed air circuit
includes also an air drier that is also included in the delivery.
3.2.3.3
Drying
Drying of a lacquer coat during the sheets travel is a vital part of the process.
Dispersion lacquers contain a considerable share of water that must be removed from the
lacquered sheet surface before its unloading in pile. A powerful drying system is used for this
purpose. Two components participate on dispersion lacquer drying - IR radiation and hot air.
The task of IR radiation is lacquer heating in order to release water in ambient atmosphere. In
this way created moisture is absorbed with hot air that is subsequently discharged from the area
of the delivery. Gaseous products arising during drying that would annoyed the operator of the
machine with odour are discharged simultaneously with moist air from the area of the loader.
Two disengaging cartridges installed in the area of the delivery are source of both drying
components. The first cartridge contains 3 IR radiators and 3 hot air units. The consequent
cartridge contain 4 sources of hot air.

Of course the IR as well as the hot air output is continuously controllable and adjustable for any
combination of printed materials.
The drying system contains a box positioned close to the delivery. Cables and abundantly
dimensioned air hoses lead out to the delivery. The box contains drying system control and two
powerful blowers - one for air supply in hot air radiators and the other one for moist air
exhaustion from the area of the delivery. Waste air can then be discharged directly in
atmosphere.
There is a touch display on the front wall of the drying system box; this touch screen is used for
control of the drying system. Besides the possibility of mutually independent adjustment of
output of IR radiators and hot air supplies, it is possible to save various settings of the drying
system for different printed materials and different printing conditions using the display. This
function can then be used by the operator for quick setting of drying parameters for repeating
jobs by reading the saved data with the control system and immediate carrying out the required
setting-up.
The drying system can be used also for drying of non-lacquered prints. Hot air drying remains
off and the output of the IR radiators is reduced adequately. It is advantageous to save such
setting of the drying system and to use it repeatedly. The drying system is a product of GRAFIX
GmbH (www.grafix-online.de).
Dispersion lacquer drying is energy highly demanding and this should be considered for electric
supply design to the printing press - see the table below.
3.2.3.4
Extended delivery
The extended delivery of the printing press is also a part of equipment for powerful lacquering
with dispersion lacquer. It was created by inserting extension in the horizontal part of the
existing high delivery. The extension length is 1,410 mm (55.5"), adapted to facilitate insertion
and connection of drying system cartridges. The selected concept of extension itself and its
covering allows simple and comfortable handling the drying system cartridges. The extension
includes also sheet guide that allows influencing sheet passage. The sheet guide consists of a
chrome-plated steel sheet with holes through which it is possible to supply compressed air
under passing sheets or to exhaust air under sheets. Moist air is exhausted from the area
between the lower and upper branches of the chain track with two tubes of a large diameter.
Some parameters of lacquering unit periphery devices are listed in the table below.

Types of packing:
On skids
Skids are suitable for intrastate truck transport directly to the customer with transport time within
two days. Parts of the machine are fixed to the skids with cross section of 100x200 mm. The
main parts of the machine on skids are anchored to the truck body using anchoring prisms and
covered with PE foil. Protection against corrosion is provided by application of preservation oil
only.
On floors
Crate floor is compliant with European international truck direct transportation within the total
transport period of twenty days. The main parts of the machine are fixed to the floor skids. After
inserting siccative, the front part of the machine is covered with foam PE and top part of PE
packing and packing is sealed. Contact with marine aerosol is not recommended.
In crates
Crates are used for European, Euro-Asian and overseas combined transport with consequent
direct transport within total transport time of 100 days. Packing in crates can be selected
according to the method of protection against corrosion:
•
•
European packing with the main machine parts protected by PE packing and
siccative. Accessories and removable parts are protected only with oil. The protection
period is 3 months for Europe-like climate environment. Contact with marine aerosol
is not recommended.
Overseas packing with multi-layer PE-AL-PET protection and siccative with
protection of all elements in crates. The machine is protected for the period of one
year for Europe-like climate environment. Marine transport and storage in harsh
climatic conditions shorten the storage period.
It is necessary to provide sufficient area for machine unpacking, i.e. to allow access of lifting
mechanisms or other lifting systems.
It is advisable to have abundant space available. It is also necessary to remember that the
distance between the place of unpacking and place of erection should be as short as possible
and this area should be provided with relatively even and solid floor (road) on which it is
possible to transport machine parts in the final installation place. The following illustrations
apply to handling the unpacked machine parts using a crane.

It is necessary to select a suitable place for final positioning of the printing press. It should
positioned so as it would not be positioned in place exposed to intensive sunshine, in the
proximity of heaters of places of more intensive air circulation. Unsuitable positioning causes
frequently printing problems. Virtually the same applies to printing shop environment like to a
paper warehouse, i.e. temperature range of 20°C ± 4°C (68°F ± 7°F) with relative humidity of
55 to 70%. Environment dustiness should be maintained as low as possible. Machine
positioning in the recommended minimum area is illustrated in the figures below.

Floor preparation
Pay adequate attention to the floor before machine installation. The floor should be horizontally
levelled and made of concrete in the best case. Gradient should not exceed 0.5 cm/m (0.06
mm/ft), however, it should not be higher than 2 cm (0.8") across the length of the machine.
The machine is supported by steel feet of 110 mm ( 4.3") diameter. Their layout is apparent
from the following figures and figures of machine working space. Floor total load capacity for
the machine feet should be at least 3,500 kg/m2 (730.7 PSF).
Dimensions of foundation for individual types of machines are illustrated in the following figure
and table. Reinforced structure of the foundation feet is made of B25 concrete and steel
reinforcement mesh SZ 8/100 x 8/150.
1) Floor
2) Foundation - B25
concrete
3) Sand-and-gravel
layer
4) Natural soil
5) Flexible dilatation
It is necessary to pay maximum attention to high-quality construction of the concrete floor under
the machine.

If the machine is installed on the floor that is not integral (paving), is uneven unacceptably or
which breaks with time, the manufacturer of the machine bears no responsibility for consequent
poor printing quality.

The switchboard can be removed if necessary. If it is necessary to remove the handles of the
lacquering unit register, both removal and reassembly should be carried in the "0" position.
If there is a central compressed air distribution system in the production premises, you can use
it after reducing the machine input prossure to 0.7 MPa (100 psi) for machine control. The
compressor for pneumatic distribution lines is not required then. Because of relatively high
noisiness of the compressors, it is not necessary to position them close to the machine. The
compressor for pneumatic installation can be positioned outside of the machine, namely within
the distance of up to 20 m (65´). The compressor for pneumatic system should be positioned
within 6 m (20').
