An example of solving the problem of sticking dirt on the back of paperboard printing

for printers, sticking dirt on the back and rubbing dirt on the back are common faults and difficult to solve. Of course, for the newly produced equipment, great improvements have been made in both the process of chlorinating white wax and the equipment mechanism, such as installing UV and IR drying devices, and increasing the paper transfer time between two adjacent units, etc. But for the printing equipment without drying device, we have to adopt the traditional method of powder spraying and small stacking. However, powder spraying often leads to the decline of the gloss of printed matter and the difficulty of laminating, and also pollutes the production environment and equipment. We know that the back sticking is caused by the residual sticking of the ink layer. 1. The skill of using the bellows ring stiffness testing machine and the positive pressure on the substrate. Therefore, the back sticking problem can be solved as long as any factor is overcome

for packaged products, most of them use thick cardboard of more than 250G/m2 for printing, so the stiffness of the cardboard is higher than that of thin paper. Jinan assaying has special personnel for equipment training and door-to-door debugging. Therefore, the semi-finished products after printing can be rotated by 90 ° and placed vertically on the side, which reduces the positive pressure between each print, thus avoiding the back sticky dirt, and the use effect is good, It is suggested that colleagues in the research and development of special processing technology and equipment for large-scale products may wish to have a try
