Color printer calibration

A method of determining substrate and ink compatibility in a printing system comprising the steps of:

• providing a test pattern having a range of ink loading levels and including test features corresponding to at least one of text and graphics;
• identifying a substrate to be used with the printing system;
• identifying an ink set to be used with the printing system;
• printing the test pattern on the identified substrate using the identified ink set;
• selecting an ink loading level for at least one of the at least one of text and graphics using the test pattern;
• and
• generating a tone scale transformation for one or more ink colors of the identified ink set using the selected ink loading level for at least one of the at least one of text and graphics, wherein the selected ink loading level for the at least one of the at least one of text and graphics is dependent on the identified substrate.
