Claim 15:
16. A method comprising:
receiving a reference halftone design;
receiving reference ink drop size data;
receiving a reference printer transfer function corresponding to the reference halftone design, a reference printer response target and a reference print substrate;
receiving first print measurement data corresponding to the reference halftone design, the reference printer transfer function and a first print substrate;
receiving first printer response target;
generating a first intermediate print substrate transfer function based on the first print measurement data and the first printer response target;
generating a first printer transfer function based on the first intermediate print substrate transfer function, the reference halftone design, the reference ink drop size data and the reference printer transfer function; and
generating a first print substrate transfer function as an approximation of a function with input values determined as the first printer transfer function evaluated at digital count values and output values determined as a composition of the first intermediate print substrate transfer function and the reference printer transfer function evaluated at the digital count values;
wherein a transfer function comprises a mapping of an input digital count to an output digital count.
