Toward a Colorimetric Specification for GAA/SWOP Proofing and Production Inks - Phase III

Over the last three years the GAA has been working toward establishing a visually based colorimetric specification for production and proofing ink colors. Phases I and II have been published in the 1988 and 1989 TAGA Proceedings. Phase III of the project, which relates to printing images within the colorimetric parameters determined in Phase II, was recently completed and analyzed. The results are a tentative colorimetric ink specification based on an ink set which can be printed with trap and dot gain consistent with SWOP and produce acceptable image quality. Repeatability and colorimetric tolerances from visual assessments are in the process of being completed.
