Abstract
This paper shows that combined color component coding can be performed for the compression of color maps. Classification, which was done to remove the printing irregularities in the maps, reduces the number of colors to a much smaller number which can be stored in a look-up table. Thus, the three bands that form the color map are replaced by a pseudo-color map. The pixel indices in this map are only pointers to their actual colors stored in the look-up table. Combined component coding increases the compression achieved with conventional coding by a factor of three.
