1. Paper jewelry box gravure printing
The printing plate of gravure printing is lower than the blank part, and the degree of depression varies with the level of the graphic. The darker the graphic level, the deeper the depth, and the blank part is on the same plane. When printing, After the ink is applied on the entire layout, the ink on the flat surface (ie, the blank part) is scraped off with an ink scraping machine to keep the ink only on the printing plate with a low concave surface, and then a substrate with strong ink absorption is placed on the surface to apply Under high pressure, the ink on the printing portion of the layout is transferred to the substrate, thereby obtaining printed matter. Because the depth of the depression of the printing portion on the layout is different, the amount of ink in the printing portion is different, and the thickness of the ink layer on the printed product It is also inconsistent. The part with more ink appears to have a lighter color than the part with less dense ink. Therefore, the picture and text appear to have different tone levels. The main feature of gravure printing is that the picture and text are added with a 45 degree screen.
