Traditional printed features

Traditional printed features


Topographical features


Because the printing of the letterpress printing surface is somewhat different from the non-printing pattern, the pressure is obviously pressed under the printing pressure. Therefore, the margin of being pressed is heavier than the base, so the marginal exposure ink . The thicker scene, so the printed product can see the marginal pressure in the unit area, this situation is called the Marginal Zone. The letterpress printing is densely colored, which is ranked second in the three major printing formats, and the ink is about 70%-80%.


Lithography characteristics


The lithographic print is softer than the relief print, and the layout is made by the principle that water and oil are not mixed with each other. Therefore, in the printing work, some of the printing marks on the printing surface are invaded by the water glue, and some lines of the printing line are severely damaged at the margin, so that the ink density of the line margin of the unit area is lightened, and the unevenness appears. Of course, the more you enter the center of the line, the more concentrated it is. This kind of scene from the light margin to the concentrated center is the basic feature of lithographic printing. However, due to the water gel and direct printing, the uniform color is evenly reduced. It is the lightest color density in the three major printing formats. The ink is about 60-70%. In other words, the lithographic printing is soft and soft.


Gravure printing features


Gravure printing is the strongest color in the three major printing formats, about 80-90% concentration. Because some of the gravure printing surface marks are submerged under the layout, in the printing process, it needs to be inked, wiped, and then printed. When printing, it is necessary to pull out the ink of the printed ink with strong pressure, so the line At the margin, the mechanical pull effect occurs, and the margin of the hair is formed, of course, the Marginal Zone scene is also the most important concept for distinguishing gravure printing. Despite this, the uniform color of gravure printing is still extremely dense, so the printed prints have some three-dimensional thickness.


Traverse printing features


Because stencil printing is necessary to drop the ink through the mesh hole, the surface of the printed matter is reflected in the cloth pattern. Most of them are printed on the enamel cloth, so the cloth pattern is generated, and other such as copper net or plastic net are the same. Together, because the ink reaches the paper surface through the mesh, the printing ink is extremely thick, and the thickness can be seen with the naked eye. Printing ink does not shine, it is also one of its characteristics
