HELIOSTAR® G
Benefits for Gravure Printing
• Better print results
• Easier to operate
• Higher flexibility
• Higher operator safety
• Higher output
• Quicker job change
• Shorter set up time
• Lower solvent retention
Increased Efficiency in Packaging Printing

HELIOSTAR® G
Inking System
WINDMÖLLER & HÖLSCHER
HELIOSTAR® G - Inking System
Inking roller
(W&H patent)
2
HELIOSTAR® G - Comparison of inking systems
„Inking“ roller at 6
o‘clock position
Streaming bars in
the ink pan
Driven inking
roller at 3 o‘clock
position
= area where ink may dry up
HELIOSTAR® G -
Features of Inking System
Pneumatic loading +
differential speed:
complete ink exchange in
the cells
Inking at 3 o‘ clock position:
No ink build-up in the cells.
Reduced entrapment of air
in the ink
Inking roller at differential
speed:
self-cleaning effect of
inking roller and gravure
cylinder

Quick Change Concept
HELIOSTAR® G -
Quick Change Concepts
HELIOSTAR ® GL
HELIOSTAR ® GE
Trolley-System
Automatic Job Change-over
4
HELIOSTAR® G No premounting of bearings, couplings + reference ring
for zero positioning
shorter preparation time
faster change over
safe handling
higher productivity
better reliability
Benefits of Both Quick Change Concepts
Automatic high torque coupling
Inking System
Ink tank preparation capability for full ink volume
No ink pulsation by centrifugal pump
Quick change for ink pan, inking roller and gravure cylinder
HELIOSTAR® GL - Benefits of
Trolley System
Combined Change of
Cylinder and Inking System
Ink tank preparation for full ink
volume (ink can remain in tank
during changeover)
Preperation of trolley and ink
during production
5
HELIOSTAR® GE - Benefits of Automatic Cassette System
Change of print cylinder
or
print cylinder and cassette
Rinsing system in print station
Ink tank preparation for full ink
volume
Preperation for automatic
change during production
HELIOSTAR® GE - Change-over concept
Production
Move out
cylinder and
ink system
Positioning
and move in
for new job

HELIOSTAR® G
Doctor Blade System
HELIOSTAR® G - doctor blade
robust, vibration
free construction
backlash-free
guides
torsion-free base
robust clampings
toolless doctor
blade and doctor
holder changeover
constant tip angle
while oscillating

HELIOSTAR® G - Doctor Blade
HELIOSTAR® G
Register Scan Preset
8
HELIOSTAR® G - RSP (Register Scan Preset)
scanning of the engraved surface in the non-printing areas
not affecting cylinder origination costs, world-wide
high sensing reliability + high accuracy
allows for the use of on-hand cylinders (manual marking capability)
suitable for use with different repeat lengths and printing widths
RSP-marks
HELIOSTAR® G - RSP (Register Scan Preset)
Automatic Pre-Register by:
Zero position scanning for defined
cylinder positioning
measurement of material length and
elongation, therefore accurate preregister even for flexible Material
(W&H patent)
less waste
time saving
additional production time
operator friendly

HELIOSTAR® G
Drying
HELIOSTAR® G - Innovative Drying System
High-precision even die gaps: consistent drying
across the entire width (no streaks like with spot
drying)
Narrow nozzles acting directly on the web
supporting rollers: maximum nozzle exit speed,
maximum drying effect
Easy to clean from the front - no “toaster effect“
Toolless removal of nozzles (can be washed in
machine)
Nozzles can be pivoted
10
HELIOSTAR® G - Drying
8 nozzles, 2.4 meters
15 nozzles, 2.4 meters
16 nozzles, 4.8 metres
30 nozzles, 4.8 metres
HELIOSTAR® G - Jumbo dryer
4 x 12 nozzles
2 or 3 temperature zones
Interconnected hoods
No additional external air
Drying path: 7.6 meters
11
HELIOSTAR® G - Drying system features
High capacity drying system with optimized nozzle design
and air flow conditions
Minimized leakage air
Modular design
Reliable solvent level monitoring by IR sensors
Higher Nozzle exit air velocity
Optimized IR sensors by W&H for shorter response times
Solvent level automatic control for minimized outgoing air
