How To Adjust The Pressure Of Flexographic Press

In the process of printing, the two adjacent rollers of the three rollers of printing plate, rubber and impression are in contact with each other and squeeze to play the role of transfer printing. In order to achieve normal ink transmission on the printing paper and truly reproduce the continuous tone words, lines, images and halftone dots of the graphic part, in addition to the contact between the two roller surfaces, the necessary printing pressure must be added. The weight of the printing pressure and the accuracy of the adjustment will directly determine the size, depth and quality of the ink color in the graphic transfer and printing dot reproduction. It is necessary to adjust the center distance between the impression cylinder and the rubber cylinder during self-adhesive printing. The center distance of the cylinder can be increased by about 0.2 ~ 0.4mm. If the paper becomes thinner from thick, the reduced thickness, that is, the lining thickness removed from the plate liner, should be added to the rubber cylinder; If the printing paper turns from thin to thick, subtract a certain thickness from the rubber cylinder liner, and add the corresponding thickness to the liner of the plate cylinder.
