Abstract

Standards relating to color data definition continue to be a dominant theme in both the US and international graphic arts standards activity. There is a growing understanding of the role that metrology and printing process definition play in helping define stable conditions to which color characterization data can be related. Standards have been published to define color measurement and computation requirements, scanner input characterization targets, four- color output characterization, and graphic arts applications for both transmission and reflection densitometry. Work continues on standards relating to ink testing, reference ink color specifications, and printing process definition. In addition, efforts are underway to document, in ANSI and ISO Technical Reports, colorimetric characterization data for those printing processes having broad-based usage. These include various applications of offset, gravure, and flexographic printing processes. Such data is key to the success of color profiles developed in accordance with the specifications being developed by the International Color Consortium. The published graphic arts imaging and color- related standards and technical reports are summarized and the current status of the work in progress is reviewed. In addition, the interaction of the formal standards programs and other industry-driven color activities is discussed.
