High-fidelity image printing method

Abstract

The invention provides a high-fidelity image printing method, which comprises the following steps that Step 100, original color images are subjected to color separation processing to obtain color separation images; Step 200, the color separation images are subjected to frequency modulation screening to obtain modulated images; Step 300, the surfaces of printed carriers are subjected to sample making to obtain sample making printing carriers; Step S400, the plate making is carried out according to the modulated images and the sample making printing carriers to obtain plate making images; Step 500, the plate making images are subjected to multi-color chromatography. The high-fidelity image printing method provided by the invention is based on the multi-color color separation principle, is combined with the high-definition frequency modulation screening and high-fidelity printing sample making technology, and has the advantages that the definition, the color saturation degree and the uniformity of color images on the surfaces of printing carriers can be enhanced, and the high quality and the full digitization of the high-fidelity image printing process are realized.

Description

【Technical field】 [0001] The invention relates to a high-fidelity image printing method. 【Background technique】 [0002] With the continuous improvement of people's requirements for color printing and visual effects of packaging and decoration, the market demand for high-fidelity printing of products will continue to increase. At present, the color decoration patterns on the surface of some product printing carriers are distorted, unstable, blurred, false in resolution, not rich in layers, and overprint moire is obvious due to their special material properties and old technology during the printing and reproduction process. Phenomena such as these have seriously affected the surface decoration effect of the product printing carrier and the market value of the product, and the color printing quality on the surface of the product printing carrier needs to be improved urgently.

AI Technical Summary

Problems solved by technology

At present, the color decoration patterns on the surface of some product printing carriers are distorted, unstable, blurred, false in resolution, not rich in layers, and overprint moire is obvious due to their special material properties and old technology during the printing and reproduction process. Such phenomena have seriously affected the surface decoration effect of the product printing carrier and the market value of the product, and the color printing quality on the surface of the printing carrier of these products needs to be improved urgently

[0003] Due to the influence of factors such as imperfect spectroscopic characteristics of the ink in the prior art, uneven deformation of AM dots, inconsistent crossing angles of dots of various colors, and non-data-based standardized control of the printing process, the color of the entire printing screen is distorted, and the difference between the same printed matter The color tone is inconsistent, the image definition is low and there are obvious moiré, etc.

[0004] At present, only a very small number of large-scale carrier printing manufacturing enterprises have begun to pay attention to it and started to conduct experimental research according to the production technology of the enterprise, but the key technology has not been resolved, due to the differences in production equipment, process conditions, product types, quality requirements, and personnel quality of each enterprise. , resulting in the possibility of further improving the high-fidelity printing quality of the color decorative pattern on the surface of the product printing carrier
