Abstract

The invention provides computer imaging type direct plate making equipment and a plate making method. The equipment comprises an exposure light source, a print image imaging device and a printing plate carrying device, which are arranged coaxially; the exposure light source is used for irradiating light to cure a photosensitive material loaded on a printing plate; the print image imaging device is used for forming a target image to replace a film, so as to mask the light from the exposure light source, and thus a corresponding exposure image is formed on the printing plate; to improve the exposure efficiency and the plate making efficiency, the print image imaging device is provided with a light guide layer for trimming non-uniform exposure light to uniform parallel light. Due to the introduction of a light homogenizing layer, dependence on a light source is further reduced, and in particular, good plate making precision can be obtained by combination of light sources with different specifications, light sources or spot light sources with different surface luminescence uniformity and line light sources. A plate making process formed by the plate making equipment can adapt to the plate making requirements of high precision and low cost.

Description

Technical field

[0001] The invention belongs to the field of printing plate making, and particularly relates to a computer imaging direct plate making device and a plate making method. Background technique

[0002] The plate-making process is an important step in the pre-press process. It plays a very important role in the entire printing process and has an extremely important impact on the color, tone and register of the printed matter. With the development of science and technology, the plate-making process has also continued to evolve, from traditional film plate making to wax-spray plate making, ink-jet plate making, to the widely used laser plate making, etc., with the development of computer technology, plate making process gradually Combining them, and continuously developing in the direction of high efficiency, environmental protection and low cost, thus forming the computer-to-plate technology.

[0003] The so-called computer-to-plate (ComputertoPlate, referred to as CTP)...
