    Abstract: In some examples, a print cartridge includes a memory device comprising quantized coefficients derived from a lossy compression, at a selected step size, of a difference color table including a plurality of difference nodes in which each difference node represents a difference 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 quantized coefficients useable to produce a reconstructed difference color table including a first set of difference nodes each representing a difference value that is within an error threshold at the selected step size, and a second set of difference nodes each representing a difference value that is outside an error threshold at the selected step size. The memory device further comprises corrective information to correct the second set of difference nodes of the reconstructed difference color table.

    Abstract: A printer cartridge includes a memory device and at least one compressed color table stored on the memory device. A compressed color table includes a losslessly compressed neutral axis, a number of nodes that correspond to seed color table nodes and a number of delta nodes that correspond to a number of delta tables. The number of delta tables indicate differences between interpolated color table nodes and corresponding actual color table nodes.
