ABSTRACT:
The presently disclosed embodiments are directed to methods and systems for improving the performance of an image processor color to color tile transformation by caching color tiles most recently calculated. A page of a print job is received. One or more color tiles based on colors found in a previous print job are pre-calculated and stored in a memory. A color present in the page is read. The color is compared to one or more pre-calculated color tiles. If the color does not match a pre-calculated color tile, a new color tile for the color is calculated, a pre-calculated color tile is removed from the memory, the new color tile is added to the memory, and the new color tile is used to print the page. If the color does match a pre-calculated color tile stored in the memory, the pre-calculated color tile is used to print the page.
