ABSTRACT:
A model-based printing method and system for generating color halftone output images corresponding to color input signals. Models for individual printer types allow predicted printer error signals to be generated which can be used to modify the color signals in such manner as to produce output signals which, when applied to the printer, create color halftone images of enhanced quality. In an alternative embodiment, output image signals are selected which minimize an error function based on the difference between (i) a predicted perceived image corresponding to the color image input as filtered by an eye-model filter and (ii) the color halftone image resulting from filtering of the output image by a filter modeling the printer followed by the eye-model filter.
