Abstract

The purpose of this study is to determine the influence of applied International Color Consortium (ICC) predefined color rendering intents on the digital printing solid colors output (Cyan, Magenta, Yellow, and Black ((CMYK]) hue and gray output (Overlap of CMY: 50%, 40%, and 40% tints) hue variation among the four ICC standard color rendering intents in a color management workflow (CMW). The experiment analyzed the effect of four ICC-specified color rendering intents (absolute, perceptual, relative, and saturation intents) on the digital color output hue of gray and solid colors. The objective of this study allowed testing of an accepted color management practice to gain a better understanding of the presumptions associated with the application of rendering intents. The experiment examined the four ICC color rendering intents as independent groups (K = 4) using a one-way analysis of variance (ANOVA) with equal n’s method (at α = 0.05) to determine the significant colorimetric variation (COLVA) of hue between the (K = 4, n = 15, and N =60) group means (averages) color deviations of these intents. With four rendering intents (groups, K = 4), a one-tailed, non-directional hypothesis was established. The conclusions of this stilly arc based upon an analysis of ANOVA test data and associated findings. The data from the ANOVA reveal significant differences in the gray hue deviation of the reproduction among the multiple ICC color rendering intents (CRT). The colorimetric data suggest that selection of a rendering intent is an important activity in a CMW as it relates to obtaining accurate output colors for a desired purpose.

Highlights

The methodologies and parameters for assessing image permanence are not yet embodied in industry standards, but the broad outlines and requirements have been published for some timei ii iii
Any projection of print life must assume constant conditions, or at least conditions that can be integrated to represent an equivalent of constant conditions
That set of constant conditions is the basis for all print life projections, and it is a good method for making scientific comparisons for the purpose of ink, media and technology development

Summary

METHODS

The methodologies and parameters for assessing image permanence are not yet embodied in industry standards, but the broad outlines and requirements have been published for some timei ii iii. The test methods used in developing this report are generally accepted and have been previously used by this company and others. The meaning of the results is perhaps less well accepted. We have used accelerated tests, allowing for reciprocity, to project print life in years
