Printing pressure can be adjusted

Printing pressure, also called embossing force, is a term often used in the printing process. The entire printing process is to solve the contradictory process between ink and paper. To transfer the graphic on the printing plate coated with ink to the printed paper, it must exert a certain pressure during the graphic transfer process. The pressure applied is called the printing pressure. People often say: "Without pressure, it is not a matter of printing." This sentence fully shows the importance of printing pressure.

Since printing pressure is so important, is it better that the pressure is greater? Of course not. In general, the appropriateness of printing pressure is often manifested by the quality of printed matter. The pressure should be based on the premise that prints have strong dots, clear graphics, bright colors, and shades of light. The smaller the better.

But the absolute ideal pressure is very difficult, because it varies with technology, experience, model, and other conditions. Nevertheless, the quality of printed products is always the only standard for all ideal pressures.

The size of the printing pressure can be adjusted, and its regulating means should be:

First, roller center distance adjustment method. By adjusting the center distance between the two rollers to increase or decrease the printing pressure, this is the most common adjustment method.

Second, the lining thickness adjustment method. Increasing or decreasing the printing pressure by increasing or decreasing the thickness of the roll lining is the most common and the most important adjustment method. This method is used when the center distance does not reach the specified distance. It is generally best not to move it. It is worth noting that it is easy to increase or decrease the thickness of the lining, which often causes a change in the diameter of the roller, resulting in an unequal circumferential speed. The result will inevitably lead to deformation of the network, misprints, double shadows, wrinkled paper, broken triangles and other faults.
