Title:
印刷階調補正方法およびその装置
Document Type and Number:
Japanese Patent JP3612200
Kind Code:
B2
Abstract:
An adjustment process for converting the dot gain of printing conditions of a given standard printing profile to the dot gain of printing conditions of a printing machine which is going to be used is facilitated. For example, with respect to the color cyan C, the printing profile is divided into a linear four-dimensional LUT for color conversion and a gradation characteristic inherent in the printing profile, i.e., an LUT of dot gain characteristics. The characteristic of an inverse function of the gradation characteristic inherent in the printing profile is set in a LUT for gradation characteristic conversion such that a change in output halftone-dot % of the LUT of the gradation characteristic inherent in the printing profile will be equalized to a change in input halftone-dot % of the LUT. In this manner, the input halftone-dot % and the output halftone-dot % agree with each other, allowing the adjustment process to match the user's sensitivity.
