[0002] The ink roller is a roller in a printing press that applies ink to the printing plate. In the printing industry, the function of the ink roller is to quantitatively and evenly deliver the printing ink to the printing plate to ensure the vividness and consistency of the printed product and save pigments. In the production process of the ink roller, an engraving device is required to engrave mesh holes on the outer wall of the ink roller to carry the ink.

[0003] Due to control errors in the production process of some ink rollers, resulting in a small amount of ink when post-throwing, or when the ink load of a roller with a small amount of ink is increased, the mesh is generally directly ground off or re-sprayed, and then the engraving device is used again for engraving.
