Method and system for processing multilayer image

Abstract

The invention discloses a method and a system for processing a multilayer image, and belongs to the technical field of image processing. The method comprises the following steps of: first selecting an image to be processed, and marking layers to be converted into spot colors in the image to be processed; then acquiring the layer information of all layers, and acquiring information about the spot colors into which the marked layers are to be converted according to the layer information of the layers to be converted; and finally determining the conversion sequence of the layers to be converted, establishing spot channels according to the information about the spot colors, performing spot color conversion on the layers to be converted according to the conversion sequence, and storing the spot colors into corresponding spot channels. According to the method and the system, a layer relationship of the same color is converted into a spot channel, the other four colors are reserved in the layers to realize the separation of the spot color from the four colors, all edition effects are achieved in the layers by utilizing the characteristic that the layers are convenient to edit, and the spot color information is converted into the corresponding spot channels, so that the problem of complexity in the manufacture of a spot color plate in package printing is solved, and production efficiency and quality are improved.

Description

technical field [0001] The invention belongs to the technical field of image processing in the packaging and printing industry, and in particular relates to a multi-layer image processing method and system. Background technique [0002] With the internationalization of the packaging market and the globalization of the development of the packaging industry, the requirements for printing quality, exquisite effects and anti-counterfeiting technology are getting higher and higher. The advantages of gravure printing have always been high speed, wide format, low consumption and less downtime, and can obtain the best printed products on various printing materials. [0003] In order to achieve the ideal effect in gravure printing, spot color printing must be used at the same time as four-color printing, and the production of spot color plates in gravure printing is generally done by hand. The overlapping sequence of the four-color layers is different, and the manual hollowing proce...

Problems solved by technology

[0003] In order to achieve the ideal effect in gravure printing, spot color printing must be used at the same time as four-color printing, and the production of spot color plates in gravure printing is generally done by hand. The overlapping sequence of the four-color layers is different, and the manual hollowing process is not only time-consuming, but also easy to miss and lead to rework, which greatly reduces production efficiency

[0004] In the gravure printing process, the production of spot color plates usually relies on the manual processing of excellent technicians, which requires technicians to be proficient in the special plate production process. During manual processing, the overlapping relationship between the spot color and the four-color layer is fully considered to avoid Missing or repeating the hollowing process, resulting in complex multi-layer processing is not only very time-consuming but also has a high risk of product quality, which means that production efficiency is overly dependent on the processing speed and processing effect of technicians
