SYSTEM AND METHOD OF SIMULTANEOUSLY MEASURING NON-UNIFORMITY OF BACKLIGHT ILLUMINATION AND PRINTING NON-UNIFORMITY, AND CHARACTERIZING A PRINTER

摘要

A method for creating a profile corresponding to transmissive media for a printer to be characterized comprises printing at least one color target on the printer, the color target comprising a sheet of a transmissive medium having a plurality of printed calibration color patches wherein a subset of the color patches also comprise uniformity calibration patches; placing the color target on a backlight; measuring the color patches to provide a common set of measurements; fitting the measurements of the uniformity calibration patches to a backlight uniformity model; fitting the measurements of the color patches to a printer uniformity model and to a printer characterization model; and generating a printer profile that is corrected for both backlight spatial non-uniformity and printer spatial non-uniformity.
