Color definition and data exchange continue to be dominant themes in both the US and international graphic arts standards activity. However, there is a growing understanding of the role that metrology and printing process definition play in helping define stable process conditions to which color characterization data can be related. Standards have already been published that define the requirements for color measurement and computation, scanner input characterization targets, four-color output characterization data sets, and graphic arts applications of densitometry. Work continues on standards relating to ink testing and ink color specifications. The numerical specifications of SWOP proof printing have been captured in ANSI standard CGATS.6-1995. Work has been completed, and Technical Report ANSI CGATS TR 001-1995 has been published, that relates the colorimetry of the printed sheet to the CMYK input for press proofing meeting SWOP and CGATS.6 specifications. Work is ongoing to provide similar data for other printing processes. Such color characterization data is key to the development of color profiles for standard printing conditions. Specifications for color profiles, to allow color definitions to be moved between color management systems, are being developed by the International Color Consortium. The existing graphic arts data exchange, process control, and color related standards are summarized and the current status of work in progress is reviewed. In addition, the interaction of the formal standards programs and other industry-driven specification activity is discussed.
