ABSTRACT:
In a digital printing apparatus in which primary colorants are selected by an error-diffusion process, a method takes into account situations in which a colorant is selectable from within the gamut defined by certain other primary colorants. In the case of a printer in which, in addition to CMYK colorants, a mid-gray colorant is also selectable, the method avoids the problem in which an error-diffusion algorithm mandates the simulation of colors outside the gamut.
