Graphic processing device and method for preprinting paper products

Abstract

The invention provides a graphic processing device and method for preprinting paper products. An image to be preprinted matches an online corrugated paper preprinting production end according to different applicability of various printing modes in a preprinting process in printing resolution, printing color, printing breadth and printing surface paper material, and then preprinting graph processing is executed according to attributes of the corrugated paper preprinting production end; Automatic and efficient graphic processing of the corrugated paper preprinting process link is realized, and the optimization of resources and time is achieved.

Description

technical field [0001] The invention relates to the field of intelligent manufacturing, in particular to a graphic processing device and method for paper preprinting. Background technique [0002] In the prior art, corrugated cardboard began at the end of the 18th century, and its application increased significantly in the early 19th century because of its light weight, low price, wide range of uses, easy production, and recyclability or even reuse. By the beginning of the 20th century, it had been fully popularized, promoted and applied for the production of packaging for various commodities. Since the packaging container made of corrugated cardboard has its unique properties and advantages for beautifying and protecting the goods inside, it has achieved great success in the competition with various packaging materials. It has become one of the main materials for making packaging containers that has been used for a long time and is developing rapidly. [0003] At present,...

Problems solved by technology

For example, flexographic printing uses a flexible plate to print directly on corrugated paper with water-based ink; the advantages are low cost, strong durability of the flexographic plate, little impact on the strength of the carton, and a large printing format, which can reach about 2.5 meters; The disadvantage is that the printing accuracy is not high, it can only reach 35-65 lines / inch, and it is difficult to make a plate for the image, so it is more suitable for printing text and simple patterns, but it cannot support image printing with high precision requirements. The printing quality is unstable and easy to print. different shades

Indirect offset printing is to print the carton surface paper first, and then mount the printed surface paper on the corrugated cardboard; the advantage is that the printed product is very fine, and the number of screen lines can reach 150 lines / inch~200 lines / inch, and the plate making is easy. The PS plate is conventionally made, and the printing quality is stable; the disadvantages are that the production process is relatively complicated, the efficiency is low, and the cost is high; the second is that the printing format is limited

At present, this graphics processing work is mainly manually adjusted by the typesetting engineer in charge of the printing process (including the image converted from text), which has the disadvantages of relying on manual experience, low efficiency, and large errors

[0006] In particular, with the rapid development of new economic models such as online e-commerce, users are increasingly using online platform channels to seek high-quality and low-cost corrugated printing suppliers. After delivery, users and printing suppliers no longer have offline communication, the traditional link of sample preparation is basically canceled, and most of the users do not have the professional knowledge and skills of corrugated paper printing, which makes the graphics of corrugated paper printing process difficult. Processing brings new difficulties, and it is difficult to ensure that the final printed corrugated paper products meet the user's preset expectations

At the same time, the convenience and ease of use of the network platform and the richness of personalized graphic content lead to further increase in the diversity and complexity of image materials faced by graphic processing, and further increase the difficulty and time-consuming cost of graphic processing.
