Abstract
A method provides reference profile density values for at least one color combination having a plurality of colors produced by a reference device using a reference colorant set, at least one overprint color combination having reference initial percent dot values (IPDVs); providing current profile density values for at least one color combination produced by a current device using a current colorant set, at least one color combination produced by the current colorant set having current IPDVs; quantifying reference theoretical percent dot values (TPDVs) as efficiency attributes using reference colorant set; quantifying current TPDVs as efficiency attributes using the current colorant set; and calculating factors that compensate for at least one difference between image data produced with the reference colorant set and image data to be printed with the current colorant set in response to reference efficiency attributes and current efficiency attributes, factors used to adjust and generate image data.
