In color printing, a lookup table (LUT) is a mapping from a computer’s color space to the ink combinations required to print these colors. An LUT will drift over time due to a variety of factors including mechanical and environmental changes, resulting in an undesirable change in the printed results. Currently, constructing a new LUT is a time consuming process. This project focused on developing a quicker method to recalibrate a printer when drift occurs.
