    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.

    Abstract: Color prediction for color printing is performed in response to loading media into a printer and initiation of a calibration sequence, using one or more sensors to measure physical properties of the media. Based at least upon the measured physical properties, an optimal preset is identified in a database and the optimal preset is loaded into the printer as a starting calibration. A difference from values in the optimal preset loaded into the printer and those of the measured physical properties is determined and the printer prints a chart. The sensors measure the chart and the measurements of the chart are used to fine tune the optimal preset. The fine tuned preset is then saved as a new media profile.
