ABSTRACT:
A method of calibrating a four color printer capable of printing three colors and black, includes the steps of: forming a minimum black data structure representing a minimum black strategy; forming a maximum black data structure representing a maximum black strategy; for each printable black level, forming a fixed black data structure; and for a specific output color value, finding the minimum and maximum black levels using the minimum and maximum black data structures, determining a desired black level between the minimum and maximum black levels according to a defined black strategy, and determining the three printing color levels from the fixed black data structure corresponding to the desired black level.
