What is the difference in quality between gravure and offset printing?

Due to the different printing methods, there are many differences in the printing quality from their respective printed products. 1, the outline of the solid text. Offset solid text does not require dots, and its edges are smooth, just like the original text. Gravure printing must have meshes in any occasion. Due to the meshes separated from each other, the outline edges of solid characters printed by gravure printing are jagged. 2, The solid part of the ink has different shades. This phenomenon is a unique phenomenon produced by the use of low-viscosity inks in gravure printing. When the ink in the depth of the mesh is transferred to the substrate such as paper, the thickness is uneven, and small spots of different shades appear. Countermeasures: Adjust the ink year, mesh angle, change the depth and shape. 3Hue changes. The same color ink, when the ink thickness is different, the hue is also different. The level of offset printing is expressed by the size of the dots, and the thickness of the ink layer is theoretically unchanged. The Acura method is especially the method of expressing the level by the depth of the mesh. The thickness of the ink film varies with the depth of the mesh. Therefore, in offset printing The change of hue that is not considered in gravure will be produced according to different layers, but this phenomenon is not easy to occur for gravures whose mesh depth is not certain.
