Multicolor digital printing technique

Abstract

The invention discloses a multicolor digital printing technique. The multicolor digital printing technique comprises the following steps that (1) flaking, proofing and imposing are conducted, specifically, flaking is conducted directly through a computer, graphics and text information needing to be printed and reproduced is input into a laser photocomposing machine after information processing and raster image processing, films are directly output, and then plate burning, imposing and full page makeup are conducted on the films; (2) color processing is conducted, specifically, a digital printer is subjected to color processing through a ColorFlow color management system; (3) starting and printing are conducted, specifically, the Indigo digital printer is directly used for printing; (4) post-press finishing is conducted; and (5) checking and discharging are conducted. Color conversion between devices is completely and automatically controlled by the ColorFlow color management system, the frequency of human intervention is decreased, the complexity of color management is reduced, the color conversion relation between the changing device and other devices can be automatically updated by the ColorFlow color management system, and the multicolor digital printing technique can be applied to the production process in real time.

Description

technical field [0001] The invention relates to the technical field of digital printing, in particular to a multi-color digital printing process. Background technique [0002] From the beginning to the present, from rough to fine, from controllable to precise, color management has become the preferred technical solution for quality control of printed matter. Color management can effectively control the color reproduction of related equipment in each printing process, so as to achieve the consistency of color reproduction of the same image, graphics, and text among different equipment. [0003] Compared with digital printing, the color management application of traditional printing is very mature, and there are a lot of successful cases for reference, and can even be borrowed directly. There is a large space for optional software and hardware, which is enough to meet the needs of most printing companies and related industries. Enterprise color management needs [0004] With...

AI Technical Summary

Problems solved by technology

[0005] First, traditional printing color management is controlled by a single device, and color conversion between devices requires human participation.

After the addition of digital printing equipment, the demand for this color conversion becomes more complicated, which increases labor intensity and affects production efficiency;

[0006] Second, the cost of traditional printing color management is high, the control is difficult, and the requirements for operators are relatively high. Therefore, most printing companies only carry out strict color management control for high-quality products

[0007] Third, traditional printing color management solutions are composed of different software and hardware devices, which means that the color management conversion engines used for color conversion between different devices are very different, which directly affects the final result of color conversion. result
