Alternatives for Print-Device Simulation: An Overview of Modern Approaches to Neutralizing Color Out

(May 2007) posted on Thu May 24, 2007

Tired of tying up presses and personnel as you try to emulate the output of your printing equipment? Discover some powerful methods you can use to improve color matching with any CMYK inkset, substrate, or line count on any printing device.

The dark hole into which print­ers are pouring money is the ignorance of having different proofs for different presses and neglecting the fact that very close matches are possible when they use one target and one appearance for all print devices. The press can be calibrated to match the color target. This allows the output of different presses and different printing technologies to match.

 

GRACoL 7 success

GRACoL (Graphic Requirements for Applications of Commercial Offset Lithography) has worked diligently for several years now to create specifications for the sheet-fed offset industry. At the time of this writing there is a GRACoL 7 standard. But the multiple-appearance trap—believing different line counts and paper qualities required different appear­ance specifications—remains a challenge. Ignoring the fact that innovations in color management takes the focus away from line count has hindered the value of this new and better specification.

IDEAlliance, an organization that validates best practices in publishing and information technology, recently real­ized that it could abandon the specifica­tion of different appearances for different line counts in favor of an NPDC (neutral print-density curve) that would allow different line counts, papers, and print devices calibrated to it to appear very close in color. G7 was born. I believe it’s a huge step forward (Figure 1).
