AI Technical Summary

Technical Problem

In existing technologies, there is a visible color difference between the laminated printed material and the customer's color sample. The lack of scientific and quantitative methods leads to unstable compensation results. Furthermore, existing solutions or models are complex, impractical, or lack sufficient compensation accuracy, failing to meet the needs of high-precision and high-efficiency printing production.

Method used

Establish a data-driven color compensation model. By acquiring target color data and printing material information, use lookup tables or machine learning models to predict dot compensation values, achieve accurate pre-press compensation, and optimize the model through a closed-loop feedback mechanism.

Benefits of technology

It achieves a high degree of consistency between the color after lamination and the target color sample, reduces color difference, improves production efficiency, adapts to various material combinations, has self-learning capabilities, and supports full-process digitalization and standardization.

Abstract

The invention discloses a film-coated printed sheet color compensation method and a storage medium. The method comprises the steps that target color data and a printing material combination of a to-be-printed file are obtained and input into a pre-established color compensation model, and a corresponding dot compensation value is output; and performing reverse dot compensation on the to-be-printed file according to the compensation value to generate a final printed file. The color compensation model is obtained based on paired color data and corresponding material information training before and after film coating, and can accurately represent a color change rule caused by a film coating process. The method further comprises a self-learning mechanism, and model parameters are continuously optimized by detecting the color of a film coating finished product and comparing the color with a target value. According to the scheme, accurate and efficient pre-compensation of the coating color is achieved, the problems of large color difference and low efficiency caused by dependence on manual experience in the prior art are effectively solved, and the method can be widely applied to printing proofing and production processes.
