Abstract
A system and method for selective color-correction when applying three-dimensional texture to a printed substrate hinges either on a metric that is elicited from the image, or as determined by an operator. The metric may be associated with the human visual acuity curve for textural information. Other textural metrics may also be used.

A method of mitigating change in image appearance due to planned application of a three-dimensional texture to a color image to be printed by an electrophotographic printer, the method comprising:
- analyzing digital data of color information for forming an image, the digital data including first information corresponding to a plurality of color layers and second information corresponding to a clear toner layer, the second information sufficient to impart a three-dimensional texture to the image;
- and
- correcting a color profile for the electrophotographic printer based on a measure of a spatial frequency of said second information.
A method of mitigating change in image appearance due to planned application of a three-dimensional texture to a color image to be printed by an electrophotographic printer, the method comprising:
- receiving digital data of color information for forming an image, the digital data including first information corresponding to a plurality of color layers and second information corresponding to a clear toner layer, the second information sufficient to impart a three-dimensional texture to the image;
- and
- interpolating between a first color profile and a second color profile, based on an amount of clear toner called for in said second information.
A method for operating an electrophotographic printing system having an electrophotographic printer and a computer used in conjunction therewith, said method comprising the steps of:
- loading on the computer software configured to mitigate change in image appearance due to planned application of a three-dimensional texture to a color image to be printed by said electrophotographic printer, the software including:
- analyzing digital data including color information for forming an image, the digital data including first information corresponding to a plurality of color layers and second information corresponding to a clear toner layer, the second information sufficient to impart a three-dimensional texture to the image;
- and
- correcting a color profile for the electrophotographic printer based on a measure of a spatial frequency of said second information.
