Non-transitory computer readable recording medium stored with color verification optimization program, color verification optimization apparatus, and color verification optimization method

A color verification optimization apparatus optimizing verification of color conversion processing using a color conversion pattern which is a combination of a color conversion profile for converting a color value of print data into a color value specific to a printing apparatus and a color correction table for correcting a color value converted by applying the color conversion profile, the apparatus comprising:

• a controller that:
• analyzes a setting of a print job and extracts a plurality of the color conversion patterns used in the print job;
• determines whether a color conversion profile of one of the extracted color conversion patterns coincides with or approximates another color conversion profile of each of the remainder of the extracted color conversion patterns by comparing color saturation values after printing which are estimated with respect to the color conversion profiles;
• determines whether a color correction table of one of the extracted color conversion patterns coincides with or approximates another color correction table of each of the remainder of the extracted color conversion patterns by comparing color saturation values after printing which are estimated with respect to the color correction tables;
• obtains the color conversion patterns in which the color conversion profiles and the color correction tables both coincide with or approximate each other based on determination results by the controller;
• and
• executes the verification by one or more of the obtained color conversion patterns and omits the verification with respect to the remainder of the obtained color conversion patterns.

The color verification optimization apparatus as claimed in claim wherein the controller:

• recognizes, when determining that the color conversion profile does not coincide with or approximate the another color conversion profile, a color value of which the color saturation values after printing are different between the color conversion profile and the another color conversion profile;
• specifies color values used in the print job;
• determines whether the recognized color value and a color value around the relevant color value are included in the specified color values, and
• when determining that the recognized color value and the color value around the relevant color value are not included in the specified color values, determines that the color conversion profile coincides with or approximates the another color conversion profile.
