In today's market, no matter what you do, you need to pay attention. Only serious, careful, love thinking that people will achieve a cause. Self-adhesive label printing should pay attention to the following points:

1, adjust the printing pressure.

In the process of offset printing, the printing plate, rubber, embossed three rollers in each of the two adjacent roller is in contact with each other, squeeze and transfer effect. In order to obtain a normal ink transfer on the printed paper, the dotted lines, lines, images, halftone dots of the graphic portion are reproduced in real terms, and these prints must be additionally printed with the necessary printing pressure in addition to the contact of the two drum surfaces effect. Printing pressure severity, adjust the degree of control is accurate, will directly determine the graphic transfer and printing network to reproduce the ink size, the level of the advantages and disadvantages. It is necessary to adjust the center distance of the impression cylinder and the blanket cylinder during the printing of the stickers, and the center distance of the drum can be increased by about 0.2 to 0.4 mm. If the paper is thinned, the reduced thickness, that is, the thickness of the lining that is drawn from the plate gasket, is added to the blanket; if the paper at the time of printing is thin and thick, Minus a certain thickness, and the corresponding thickness of the plate cylinder into the liner to go.

When the plate is pressed, compacted, it is prevented from running relative to the printing. In the production practice, the ideal printing pressure is controlled at about 0.15-0.25mm. It is necessary to emphasize the ideal printing pressure, that is, In the case of deformation, the imprint of the graphic part of the plate is sufficiently strong on the basis of the firmness of the paper and the clearness of the net.

2, in the adhesive label printing should pay attention to the adjustment of the feeding section. It is necessary to transfer the paper part of the suction nozzle and the amount of air blowing paper should be adjusted accordingly.

3, India stickers because it is the thickness of two layers of coated paper, paper thickness should pay attention to double the gap between the controller should also be a corresponding increase in the side of the regulation and the regulation of the gap between the paper and the paper Increase some.

4, sub-paper suction nozzle, feeding nozzle to replace the larger diameter and larger thickness of the rubber apron, in order to achieve smooth paper feeding, paper roll does not swing the purpose.

5, the distance between the delivery pad and the surface of the impression cylinder and the distance between the delivery pad and the paper feed pad are increased and the distance is approximately equal to the thickness of the paper plus 0.3 mm.
