Patent ID: 6930790

Claim:
A method for testing a printing system by using a color-managed output system, comprising; providing a page having one or more test colors, each test color appearing alone in a separate test region of the page, each test color being defined by an application color value in an application color-managed color space; for each test color, converting the application color value into a standard color value in a standard color space using a color profile associated with the printing system; specifying a range of acceptable standard color values in the standard color space for each test color; redefining in the output system a mapping from the standard color space to an output system color space, whereupon the acceptable standard color values map to a set of success output system color values and other standard color values map to a set of failure output system color values; and testing the color conversion accuracy of the printing system by printing the page from the printing system to the output system, wherein the printing includes using the mapping to obtain an output system color value for each test color and producing the output system color value on a print output, whereby the color conversion accuracy of the printing system can be evaluated according to the presence or absence of success output system color values in one or more diagnostic regions of the print output or the presence or absence of failure output system color values in the one or more diagnostic regions of the print output.
