Classification: CPC G  B  H | IPC B  G

Claim 10:
11. At least one non-transitory computer readable medium having instructions stored thereon, which when executed by one or more processors, cause the processors to:
receive a reference halftone design;
receive reference ink drop size data;
receive a reference printer transfer function corresponding to the reference halftone design, a reference printer response target and a reference print substrate;
receive first print measurement data corresponding to the reference halftone design, the reference printer transfer function and a first print substrate;
receive first printer response target;
generate a first intermediate print substrate transfer function based on the first print measurement data and the first printer response target;
generate 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
generate 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.
