Background
Intaglio printing is called intaglio printing for short and is one of four printing modes. Intaglio printing is a direct printing method, which directly imprints the ink contained in the intaglio pits on a printing stock, wherein the shade level of the printed picture is determined by the size and the depth of the pits, if the pits are deeper, the contained ink is more, and the ink layer left on the printed matter after impressing is thicker; conversely, if the pit is shallow, the amount of ink contained is small, and the ink layer left on the substrate after the imprint is thin. Intaglio printing is one of printing processes, and the advantages of thick ink layer, bright color, high saturation, high printing plate printing resistance, stable quality of printed products, high printing speed and the like of the intaglio printing occupy an extremely important position in the fields of printing packaging and graphic publishing. The gravure printing roller is a mold product widely used for plastic flexible packaging, cigarette and wine paper packaging, decorative paper wallpaper, floor leather and capsule cover printing.
The kind of gravure printing is classified into two types according to the plate making method: engraved intaglio plates and etched intaglio plates. The existing corrosion printing plate processing easily has the problem that the corrosion is too incomplete or the depth is not enough to meet the requirement. The engraved intaglio may be divided into a manual engraved intaglio, a mechanical engraved intaglio and an electronic engraved intaglio according to a control method of a nicking tool. The problems of heavy manual labor, high plate-making cost and long period exist in the manual engraving intaglio processing, the problems of higher cost and long plate-making period exist in the mechanical engraving intaglio processing, the application range is limited, and the problem of electric engraving and needle punching caused by plating factors exists in the electronic engraving intaglio processing.
