Study on Fidelity of Inkjet Dots Based on Multiple Linear Regression Analysis

Abstract

The paper is intended to study the relationship between ink dot fidelity, color gamut, solid density and dot gain. The method of multiple linear regression is adopted to analyze the above relationship, and then determine the evaluation parameters of the effect of printing color reproduction. Finally, it obtains the nonlinear relationship between ink dot fidelity and color gamut, also the linear relationship between ink dot fidelity and dot gain, solid density, and establish corresponding mathematical models through inkjet printing experiment. The correlation coefficient method verifies that the fidelity of ink dots can be replaced by the solid density and dot gain as the quality control parameters of ink jet printing.
