Abstract
In some examples, a print cartridge component includes a memory device comprising coefficients based on a compression of a difference table including a plurality of difference nodes in which each difference node represents a value that is a difference of a value of a node of a color table and a value of a corresponding node of a reference table, the coefficients useable to produce a reconstructed difference table, and residue information representing a difference of the color table and the reconstructed difference table.
