In the process of printing, there will be various problems, including printing process, printing ink, printing production and so on. Printing double shadow is the problem to be solved now. The stroke edge of printing handwriting is inverted, and printing double shadow occurs. This is one of the common problems in the process of printing production. Let's solve the problem of printing double shadow.
The pressure here is divided into up pressure and down pressure. Up pressure refers to the gap between anilox roller and printing wheel. Down pressure refers to the gap between printing wheel and printing pressing wheel. Large pressure leads to small clearance, and small pressure leads to large clearance. The effect of overpressure is different from that of overpressure. In case of double shadow, it is necessary to carefully observe the printing effect. If the double shadow appears around the writing strokes, it is caused by excessive upward pressure. The upward pressure should be appropriately reduced, that is, the gap between the anilox roller and the printing wheel should be appropriately enlarged, subject to the paper feeding direction. If the double shadow appears below the paper feeding direction, it is caused by excessive downward pressure. To reduce the press down, that is, to increase the gap between the printing wheels, the effect will be improved.
In the actual production process, we often encounter the situation of field edition and small print edition. In the printing process, if we want to make the field edition smooth and full, the pressure should be appropriately large, but at the same time, it will cause the small print to have a double image. In addition to the above factors, there are other factors, such as poor transfer of ink itself, uneven paperboard, and uneven compressive strength. When printing, to achieve a bright color, full and good coverage, the first consideration is to adjust the parameters of the equipment, including the pressure. Although the cushion can play a good role in cushioning, the possibility of double shadow cannot be fundamentally avoided.
If you want to produce exquisite printing products, you should pay attention to a lot during printing, not only during printing, but also during design. The above is the solution to the problem of double shadow printing, and you should pay more attention during printing.
