Patent ID: 8305642

Claim:
A method for correlating uniformity compensation in a printer across different halftone screens, including: generating a first uniformity compensation profile comprising a tone reproduction curve (TRC) and first spatially varying TRC corrections (SVT) for a first set of printer colors printed with a first halftone screen by measuring printer performance relative to a target set of characterizing patches; modeling corrected printer performance for a second set of printer colors printed with a second halftone screen by scaling the first SVT with a scaling factor to generate a second SVT corresponding to the second halftone screen about the mean of the first SVT; and, predicting a second uniformity compensation profile for the second set of printer colors and the second halftone screen in accordance with the modeling for reducing printer performance measurements in generating the second SVT, wherein the first and second uniformity compensation profiles are correlated by the equation R′(x)=S*R(x)+ R *(1−S) where R (x) is a halftone patch reflectance profile comprising the first uniformity compensation profile, S is the scaling factor generated in accordance with at least one maximized image quality metric, R is the mean of R (x) and R′ (x) is a halftone patch profile corresponding to the second uniformity compensation profile.
