Analysis of ROP Color Based on Equivalent Neutral Density Considerations.

One of the initial requirements of any color reproduction system is that it reproduce the neutral scale. The knowledge of the requirements for this type of reproduction is desirous, especially in view of the increasing demands for color reproduction systems that reduce, or even eliminate, manual color correction. This paper describes an equivalent neutral density (END) analysis as applied to high-speed letterpress printing using newsprint and the ANPA-AAAA recommended colors.
