Abstract
An example method of linearizing print outputs for a printing system is described. The method involves retrieving a look-up table comprising a plurality of nodes that map input space values to Neugebauer Primary Area Coverage vectors. The printing system is used to print a set of ramps, each ramp comprising a plurality of test areas. The test areas for each ramp are defined by varying vector element values corresponding to input space values that vary in a dimension of the input space. A property of each of the printed test areas is measured and a linearization function is determined based on those measured properties. The linearization function is then applied to the input space values for the plurality of nodes in the look-up table.
