What are the operations of gravure printing on stainless steel signs?2

Stainless steel sign is an advertisement sign made of stainless steel plate and then processed by means of corrosion, die casting or printing. Most of the stainless steel signs used at this stage are made by corrosion technology, such signs have the characteristics of beautiful patterns, clear lines, appropriate depth, flat bottom surface, full color, uniform wire drawing, consistent surface color, etc. The intaglio printing of stainless steel plate is characterized by long-term and high-quality printing, short production time and good effect. In addition, the gravure roller has long service life, very large output, and does not degrade due to the number of uses. Give an example of gravure printing for stainless steel signs. It uses a depressed or sunken surface image. The image field includes honeycomb cells or wells, etched or carved into copper cylinders. The representative image of the etching area or the unprinted area of the cylinder. The ink in the cylinder rotating bathtub is called ink pool. Due to the cylinder, the excess erase ink roller is made of flexible steel scraper. The remaining ink embedded in the cell morphology image is directly transferred to the substrate (Or other materials) As it passes between the printing plate cylinder and the embossing cylinder. The intaglio printing operations of the main business units are roughly divided into the following four points: 1. Image preparation 2. Cylinder preparation 3. Printing 4. Finishing the above is the intaglio printing operation in stainless steel signs.
