Color Reproduction Based on Red, Green, and Blue Primaries for a Cyan-, Magenta-, and Yellow-Based Hardcopy Device

Abstract

This report presents a procedure that is used to reproduce custom colors on color hardcopy. The set of custom colors is comprised of red, green and blue (RGB) intensities, where intensity levels range from 0 (no intensity) to 255 (maximum intensity). The hardcopy device that produced the results in this report normally transforms RGB colors into cyan, magenta, yellow, and black. However, adding black ink during the printing process tends to cause the loss of some low-intensity colors and an overall graying of the output image. This phenomenon has been termed 'color drop-out.' The procedure described eliminates color drop-out in custom color reproduction by omitting black ink. This approach more accurately reproduced custom colors for the data set used in this study. Two other less successful methods are also presented. Mapping, Charting, Color reproduction, Compressed aeronautical chart.
