Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of printing equipment, and more particularly to a vertical plate-making equipment. Background Art

[0002] Disclosing the information of this background art section is only intended to enhance the understanding of the overall background of the present disclosure, and is not necessarily regarded as an admission or an implication in any form that this information constitutes related art that is already known to those of ordinary skill in the art.

[0003] A laser plate-making machine uses a computer to project and expose pre-designed graphics and texts onto a screen plate coated with photosensitive glue by means of a micromirror technology, realizing a direct computer plate-making method and eliminating the need for films. Currently, the traditional plate-making method is usually adopted, where photosensitive materials such as films are laminated, and through steps such as exposure, hardening, and rinsing, the graphic part is retained for subsequent printing production.

[0004] In the related art, screen printing plate-making usually adopts the method of laminating a film on a screen plate and then plate-making by means of exposure, hardening, and rinsing. However, the screen plate produced by this method has low precision, many unstable factors, and many process steps and high costs.

[0005] Laser plate-making uses DMD direct imaging technology to eliminate film consumption and directly image the pattern on the screen plate, producing a high-precision screen plate. Although there are already computer direct plate-making machines on the market gradually replacing the traditional plate-making method, they generally adopt a horizontal structure. For the production of large screen plates, the equipment has a large size, occupies a large area, and has high requirements for the space of the plate-making room.
