Sandpaper digital plate, also known as sandpaper digital plate, is a printing plate material used for digital printing. The production principle of sandpaper digital plates is to use the hardness and wear resistance of sand particles to manufacture printing relief plates.


In the process of making a sandpaper digital version, it is first necessary to apply a photosensitive material to the sandpaper, and then expose it to ultraviolet radiation to form a pattern of the photosensitive material. Next, use a strong alkaline solution to corrode the unexposed photosensitive material, and finally spray paint on sandpaper to form a printing layout with raised patterns.


Sandpaper, as a material with high hardness and strong wear resistance, can withstand processing processes such as high-pressure and high-temperature stamping, cutting, and sanding. At the same time, the surface of sandpaper has rough sand particles, which can increase the friction of the layout, making the color of the printed material more full and layered.


Therefore, using sandpaper as the material for digital printing can ensure the quality of the layout and printing effect. In addition, sandpaper digital printing has the advantages of high printing accuracy, long service life, and durability, making it widely used in the field of digital printing.
