Abstract
A color reproduction controller accesses corrected color values for driving an output color reproduction device by forming, for each color value of each pixel to be reproduced, a data pointer comprising a first word portion of a first color value and second and third word portions of second and third color values, the second and third word portions being smaller than the first word portion. The resultant words are smaller than those of the combined length of the color values from which they are formed and result in significantly smaller memory space.
