Matching the perception of a digital image data file to a legacy hardcopy
Abstract:
A system/method for generating one or more new hardcopy prints from an electronic file comprising original digital image data, wherein the new hardcopy print(s) match a legacy hardcopy previously generated from the original digital image data of the electronic file, even when the legacy hardcopy was printed from an “enhanced” or “tuned” version of the original image data. The original image data and scanner data derived by scanning the legacy hardcopy are used to identify corresponding areas of constant color in the original data and the legacy hardcopy. The corresponding color areas are represented in a colorimetric color space and the original data color values are adjusted to match the legacy hardcopy color values. The adjusted data are used to print a new hardcopy. The colorimetric color space conversion is completed using a plurality of different printing device assumptions, and the printing device assumption resulting in the smallest starting color difference between the original color values and legacy hardcopy color areas is used for the color matching process.
