Proofing method and apparatus that selects the kind of media type and transformation of the input color gamut based on the output device and the results of comparison with a scanned image using a spectrophotometer

摘要

A method of and apparatus for producing a validated print-out. The method includes creating a modified virtual image which includes the data from the original virtual image and a virtual original series of color patches representative of a color gamut. A printed series of the color patches representative of the color gamut using a spectrophotometer to provide a spectrophotometer output is scanned. The spectrophotometer output is analyzed using the processor to compare the output to an admissible range stored in a memory. If the output is within the admissible range, the print-out of the modified virtual image is validated. If the output is outside of the admissible range, the print-out of the modified virtual image is either validated after an analysis of the position of the data points of the modified virtual image in relation to an admissible color gamut, or the modified virtual image is changed.
