ISO2846 Compliant Screen Printing Inks
UviSPEED Four-Color Process Screen Printing Inks ISO 2846 Compliant Meets G7 Process Control Recommendations UviSPEED is a Fujifilm Sericol name describing halftone screen inks used for screen printing of short-term graphics such as Point-of-Purchase signage, displays and promotional materials typically printed on multi-color presses. These inks comply with the ISO 2846 color standard. ISO 2846 establishes specifications for color and transparency of four color process ink for four-color printing. In addition, UviSPEED inks are developed to meet high speed print conditions. UviSPEED inks incorporate a lower ink rheology that provides improved ink flow out on the screen and achieves excellent release from the screen at extremely high print speeds while using minimal UV energy (80-130 mJ/cm2 of UVA) for curing. UviSPEED inks print with a superior low dot profile and hold the dot structure over long press runs. Background The matching of screen, offset, or inkjet prints to a proof has always presented a challenge to printers. The photographic proofing systems used in the past (Chromalin) offered a useful visual target, but made an outright match almost impossible, as the method of producing proofs uses technology with a color gamut that volume print technologies cannot match. More recently, inkjet proofing has become more common. A current color process control method that affords a real benefit to printers is called G7. G7 is an Idealliance specification (target) that defines process controls for the neutrality and tonality of an image whether on a proof or from a press of any kind. When the G7 method is used in an inkjet proofing device, it produces a proof that more closely fits the color gamut achievable by screen, offset or inkjet. These proofs are now replacing other proofing methods, as they more closely represent the eventual printed result. The G7 gray balance and Neutral Print Density Curves are being used to develop a family of characterization data sets (i.e. profiles) that for the first time have a shared visual appearance. For print buyers there is a clear advantage, as they might be placing a campaign with a number of different printers requiring some items printed by screen, some offset or inkjet. Being able to show the end client a realistic proof is a real advantage - knowing the printed output will ‘match’. The benefits of using UviSPEED four color process screen printing inks (ISO 2846 compliant as recommended when using the G7 color process control method) are: • Quicker and easier matching of proofs – Reduced adjustments to color on press – Reduced set-up times – Reduced ink waste • Better quality prints – Wider color gamut – More accurate representation of proof • Business improvements – More effective screen print process – Common understanding of color expectation between printer and client Conclusion UviSPEED four color process inks should help enhance the business of screen printers by making them better able to satisfy print buyer demands.
