Title:
COLOR DENSITY CHARACTERISTIC CURVE COLLECTION METHOD FOR PRINTING
Document Type and Number:
WIPO Patent Application WO/2024/011659
Kind Code:
A1
Abstract:
A color density characteristic curve collection method for printing, the method comprising: designing an N-order standard color gradation diagram of a single-color channel; performing printing output and scanning correction on the N-order standard color gradation diagram; performing a boundary searching operation on the corrected diagram; partitioning the diagram; and performing deviation calculation. The method is successively used for each color channel, such that color density characteristic curves of all color channels can be obtained. Such method provides a basis for solving the problem of the deviation of color density characteristics at different positions.
