Abstract:
Embodiments of the invention concern automatic color separation with a white ink for colored and/or transparent substrate, automatic color separation with a silver ink for a natural rendering, automatic color separation with a varnish which has a gloss scale different from that of the printed sample for all shades of gloss that are possible between high glossy to high matte for a false third rendering, automatic color variation with variable thickness under the inks, and variable gamut mapping for a low contrast space.
