Abstract
Improved methods are provided for calibrating color on a color display coupled to a computer, which are useful for obtaining calibrated data in a virtual proof network for enabling different color devices to render consistent color. Methods involve user interactions with screens on the display to set color display parameters. An apparatus is also provided for calibrating a sensor which may be used for measuring color of a display in one or more of these methods.

A computer-readable storage medium encoded with a computer program comprising:
- one or more screens displayable at a client computer enabling collection of data characterizing at least the effects of viewing conditions on color reproduction by a rendering device associated with said client computer, wherein at least said data collected is used in computing a first gamut for said rendering device;
- and
- software providing a comparison of said first gamut with a second gamut of colors for reproduction by said rendering device, said second gamut of colors being provided by a server employing a network protocol.
A system for color processing comprising:
- a server having a network interface for communication with at least a client computer;
- and
- software executable by one or more networked computers and data, wherein said data comprise calibration data for one or more rendering devices associated with said client computer and first gamut data comprising at least the effects of viewing conditions for at least one of said one or more rendering devices, and said software comprises a program for comparison of said first gamut with a second gamut of colors provided by said server for reproduction by said at least one of said one or more rendering devices.
A method of color processing comprising the steps of:
- displaying one or more screens on a client computer enabling collection of data characterizing at least the effects of viewing conditions on color reproduction by a rendering device associated with said client computer;
- computing a first gamut for said rendering device in accordance with at least said collected data;
- and
- comparing said first gamut with a second gamut comprising one or more colors provided by a server employing a network protocol for reproduction by said rendering device.
