Abstract
One embodiment comprises a system that stores a pre-defined color conversion table and a hash table. The system receives user-defined color conversions for a print job, stores them in first locations in the hash table, and marks the first locations as persistent. The system processes the print job utilizing the color conversion table to convert colors in the print job to the output color space, and responsive to encountering colors in the print job that do not have color conversions in the color conversion table, interpolates between color conversions in the color conversion table to generate new color conversions, stores the new color conversions in second locations in the hash table, and marks the second locations as non-persistent. The system determines that the hash table is to be re-initialized, allows reuse of the second locations in the hash table, and prevents reuse of the first locations in the hash table.
