Abstract
Methods are described for calibrating a virtual printer including a plurality of color marking engines. The methods include printing a test pattern on one of the marking engines, the test pattern including a plurality of test patches, each test patch including corresponding expected colorimetric values, reading the test pattern with a colorimeter to determine measured colorimetric values associated with each of the test patches, and creating a lookup table that maps the measured colorimetric values to the expected colorimetric values.
