Embodiment Construction

[0018] Such as figure 1 Shown, a kind of preparation technology of gravure plate roll is characterized in that comprising the steps:

[0019] (1) Production of printing plate substrate: According to the drawings of the printing plate rollers used in the printing machine, select seamless steel pipes for cutting, welding flanges, car chamfering, and grinding the surface of the printing plate rollers;

[0020] Selection of seamless steel pipes: the weight ranges from 10kg (narrow and small printing presses) to hundreds of kilograms (wide and large printing presses, monochrome gravure printing presses), and the wall thickness of steel pipes ranges from 10mm to 30mm;

[0021] (2) Copper plating treatment of the printing plate roller: use the sulfate copper plating method, and then go through the cutting process of the car-grinding machine or the polishing process of the grinding machine grinding and polishing machine;

[0022] (3) Manuscript image file production: scan the origina...

Abstract

The invention discloses a preparation technology of a gravure plate roller. The preparation technology comprises the following steps: preparing a printing plate base body; carrying out copper coating processing on a printing plate roller; preparing an original image file; electronically engraving and preparing a printing plate image; chroming the printing plate roller. When the printing plate roller is prepared, the utilization rate of steel products is high, the working allowance of steel is low, the preparation cost of the roller is reduced, the prepared plate roller accords with the operating requirement, and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of printing plate rolls, and in particular relates to a preparation process of gravure plate rolls. Background technique [0002] Gravure printing is a kind of printing process. It is characterized by thick ink layer of printed products, bright colors, high saturation, high printing durability, stable quality of printed products, fast printing speed, suitable for printing on metal objects, etc. , it occupies an important position in the field of packaging printing and graphic publishing. The disadvantages are that compared with offset printing, the plate roller is more expensive, the ink is not conducive to environmental protection, the drying is slow, and the process characteristics are relatively special. [0003] From the perspective of application, gravure printing is mainly used for fine publications such as magazines and product catalogs, packaging printing and printing of securities such as banknotes...
