COLOR LOOK UP TABLE COMPRESSION

A print cartridge includes a memory device with data to reconstruct a color table for a printing device. The data include a compressed bitstream stored in the memory device with a plurality of quantized coefficients from a lossy compression of a plurality of difference nodes of a difference color table at a selected step size. The value of each node in the difference color table is to be added to the corresponding node in the value of a corresponding node of a reference table stored on the printing device. Corrective information for a set of nodes to be modified with residual values is included. The quantized coefficients and the corrective information are compressed. The step size information is also included.
