An evaluation method of color reproduction accuracy of digital printing based on characteristic color

Abstract

The invention discloses an evaluation method for digital printing color reproduction precision based on a characteristic color. The evaluation method mainly comprises the following steps of a first step, screening the characteristic color; a second step, designing and manufacturing a control strip, and establishing a characteristic color standard database; a third step, reproducing the color of the characteristic color; a fourth step, acquiring data of the characteristic color L*a*b*; and a fifth step, analyzing and processing the color data of the characteristic color, thereby obtaining an evaluation result. The invention provides an objective evaluation method for the digital printing color reproduction precision, wherein the evaluation method has advantages of high efficiency, high precision and high practicability. The evaluation method realizes functions of simple operation, high effectiveness, low cost, high accuracy and convenient management for digital printing production.

Description

technical field [0001] The invention belongs to the field of textile printing and dyeing, in particular to a method for evaluating color reproduction accuracy of digital printing based on characteristic colors. Background technique [0002] It is well known that the color reproduction accuracy of digital printing will directly affect the quality of color image reproduction. The color reproduction accuracy evaluation method is the main way to judge the color reproduction results, and it is a means to measure whether the color reproduction quality of color digital printing products is qualified. In the current field of textile printing and dyeing, the evaluation of color reproduction accuracy mainly depends on the experience and feeling of customers and operators, and is greatly affected by factors such as the evaluator's psychological state, lighting and observation conditions, environment, background color, etc., which is too subjective and often This leads to poor consiste...

Problems solved by technology

[0004] Aiming at the bottleneck problem existing in the evaluation method of color reproduction accuracy in the field of textile printing and dyeing, the present invention provides a simple, effective, low-cost, and high-accuracy evaluation method of digital printing color reproduction accuracy. The method is based on customer confirmation samples and actual products. The color contrast and the color difference of each characteristic color between the two are used to objectively evaluate the color reproduction accuracy, which solves the problem of strong dependence on personnel and poor scientificity of the subjective evaluation method, and is of great significance to the actual digital printing of high-quality digital printing products. and practical value
