Three Component Color Representations for Graphic Arts

This paper and the contribution from William Kress, which follows, review scientific and engineering considerations pertinent to the specification of standards for exchange of color images. The focus of the discussion is device independent (and, therefore, three dimensional) color notations. The relevance is to desktop application software which finds increasing use in Graphic Arts production cycles. The goal is to establish defaults which dovetail industry conventions with de facto standards promoted by the application developers. Reasons for proposing several defaults will be discussed as will proposals for the default definitions and their technical and scientific underpinnings.
