Abstract
Virtual ink channels are created with colored media and white ink to afford multi-channel ICC profile creation by using ICC profiling software. The available color gamut is enhanced for an device that defines a color space with a color profiler, e.g. an ICC profiler. Thus, an available color gamut for an input or output device is enhanced or extended by creating virtual ink channels for use with profiling software. This allows the use of media types and/or inks that are otherwise not supported by the profiling software.
Claims17
A method for enhancing or extending an available color gamut in a print device, comprising:
- providing a processor executing instructions for creating a virtual ink channel;
- said processor using said virtual ink channel to generate a multi-channel profile for use in said print device;
- said processor applying said virtual ink channel within a color management system to print desired colors correctly on a colored media;
- and
- said processor causing said print device to print on said colored media using said color management system;
- wherein said virtual ink channel is created based upon the color of said colored media.

A method for enhancing or extending an available color gamut in a print device, comprising:
- providing a processor executing instructions for creating a virtual ink channel for a selected media color from a white ink channel;
- inverting said white ink channel;
- said processor using said virtual ink channel to generate a multi-channel profile for use in said print device;
- and
- applying said virtual ink channel within a color management system to print desired colors correctly;
- and
- causing said print device to print on a media of said selected media color using said color management system.
