Abstract
A color table is modulated. The color table includes a plurality of nodes, and each node corresponds with a color input in the first color space and provides a print output in a second color space. The set of the plurality of nodes are arranged in a vector of a first color perception parameter. The vector can be arranged according to an order of increasing second color perception parameter in the first color space to an end node of the set of the plurality of nodes. A node in the set of the plurality of nodes that provides a peak amount of the second color perception parameter on the medium is determined. The print output for the end node is replaced with a print output corresponding with the node that provides the peak amount of the second color perception parameter on the medium.
