Color Hue and Ink Transfer - Their Relation to Perfect Reproduction.

Photographic masking and electronic scanning have had as their principal objectives, corrections based on the major hue errors of printing inks. They are capable of satisfactorily accomplishing these corrections with many of the colored inks in use today, but reasonable facsimile is still not always obtained without further hand corrections. It must then be true that other reproduction errors besides individual hue errors are significantly large under certain conditions, and these possible conditions have not been completely understood or clearly defined to the practical worker. It is the purpose of this paper to survey some of these error conditions in color printing and the added or changed masking corrections then required.
