Presswork expression enhancement method and system based on high-fidelity image-hiding

Abstract

The invention provides a presswork expression enhancement method and system based on high-fidelity image-hiding, and relates to the technical field of presswork expression. The method comprises the following steps: determining a design parameter through the early design and before-printing analysis to the presswork, hiding multilayer high-definition base images associated with a surface image under a full-color high-quality surface image through the adoption of a high-fidelity image-hiding netting system; through the prediction and optimal compensation of the color overlapping, obtaining the presswork with high expression by a printing system, wherein each layer of clear base image can be gradually observed through the corresponding detection measurement. Through the adoption of the presswork expression enhancement method and system based on the high-fidelity image-hiding provided by the invention, the complete causal relationship between the surface image and the base image can be expressed, the expression of the presswork is effectively improved, and the selection range of each of the surface image and the base image is enlarged.

Description

Technical field: [0001] The invention relates to the technical field of expressiveness of printed matter, in particular to a method and system for enhancing expressiveness of printed matter based on high-fidelity image collection. Background technique: [0002] The technique of hiding other images or information within printed diagrams has a long history. With the digital development of printing, more and more technical methods for hiding images or information have been developed and applied, and its most widely used is in the field of anti-counterfeiting, but it has not been widely used in improving the expressiveness of printed matter. [0003] In the hidden image technology, the actual displayed image that the observer can see is called the surface image, and the image that is hidden under the surface image through a specific technology, cannot be distinguished by the naked eye, and can only be seen through the corresponding detection means is called the image. Basemap, ...

Problems solved by technology

For example, in the phototypesetting, plate making and printing process of offset printing or flexo printing, there is distortion in every step, and in the process of exposure, development, conversion and fusion in laser printing in digital printing, the distortion in every step is quite serious. These distortions Will seriously affect the quality of the final printed chart

In the current existing technology, dot distortion (including dot diffusion) is difficult to predict, and it is difficult to consider the dot distortion in the printin...
