Patent ID: 8760704

Claim:
A system for controlling color reproduction comprising: a plurality of sites linked for communication through network interfaces, said communication employing one or more network protocols, wherein each of said sites has a computer system or a programmable processor; a plurality of rendering devices, in which two or more of said rendering devices are linked to the computer system or programmable processor of at least two of said sites; and memory associated with one or more of said sites for storing data and programs, wherein said data comprise color image data and one or more files having a header with information related to transformation of said color image data for rendering on said rendering devices, said one or more files further comprising one or more data structures expressing the relationship between color gamuts of said rendering devices in device independent units, and wherein said programs comprise: a program enabling a user to create annotations marking up a soft video copy of said color image data without altering said color image data; at least one of image retouching software or a page layout program; and one or more programs for rendering said color image data in accordance with a color transformation on each of said two or more of said rendering devices comprising adjustment of gamut to satisfy a criterion for color matching in which said criterion is at least partly based upon state of calibration and capabilities of the rendering device.
