Printing pressure debugging

Correctly-adapted printing pressure is the key to print quality. In particular, screen dot screen printing has high requirements for printing pressure. The correct printing pressure can print out fine and high-quality products.

1, the pressure of the uniform ink device

This pressure zone refers to the pressure between the uniform ink roller and the anilox roller. Its main function is to control the size and uniformity of ink transfer. The pressure between the two rollers is large (the gap is small), and the amount of ink on the anilox roller is relatively small, whereas the amount of ink is larger. The size of this printing pressure is related to the size of the printing area. In general, the pressure of the larger printing area can be lighter to increase the amount of ink and ink to increase the thickness and vividness of the ink layer. The smaller print area and more delicate text patterns, the pressure will be slightly larger, in order to reduce the amount of ink to improve the clarity of small text, the principle of the size of the pressure generally depends on the characteristics of the product. When printing at the outlets, the pressure is relatively large, the pressure of the fine text lines can be slightly larger, and the characters of the large print and large field products can be relatively small.

2, the pressure of the ink transfer device

The effect of the pressure between the anilox roller and the plate roller is to evenly transfer the ink on the anilox roller to the printing plate surface. The correctness of this pressure has a great influence on the clarity of the printing. The pressure of the anilox roller on the printing roller is large, the printed text pattern is thicker, double-image, anti-white, and the small font is blurred. When the flexographic printing dots are printed out, the image will be greatly enlarged, and the tone level will be darkened and changed. Deep, poor image clarity, and pressure at the same time, make printing plate printing rate decline, and easy to heap ink, printing "irregular fat" deformation defects. If the embossing force is too light, the ink of the anilox roller cannot be transferred to the printing plate, and printing cannot be performed. The optimum printing pressure should be that the anilox roller is in horizontal contact with the printing plate.

3, the pressure of the imprinting device

This pressure refers to the printing pressure of the platen roller and the platen roller on the paperboard. The effect of this pressure is that the ink layer on the plate is accurately transferred to the paperboard. In the printing process, this is the last key and the pressure is too great. Printed flexographic dots are spread out, with light colors in the middle and deep circles around the edges, which have a great influence on the image layer. The text line version is printed on both sides of the print, the small font is easy to blur, and there is a clear sense of depression in the hand. The correct pressure is when the printing surface (projecting part) of the printing is in contact with the cardboard, the dot expansion is minimal, the word line is clear, the double-printing is not spread, the text image is all printed out, and the phenomenon of no leak is best. The depth of the paperboard is not more than 0.3mm. At the same time, it is necessary to adjust the paperboard according to the specific conditions of printing to keep it in the best condition during the printing process.
