In the packaging and printing industry, for printing workers, sticking and rubbing on the back is not only a common fault, but also a difficult problem to solve. Of course, for the newly produced equipment, great improvements have been made in both process and equipment mechanism, such as installing UV and IR drying devices and increasing the paper transfer time between two adjacent units.Troubleshooting Of Sticking Dirt On The Back Of Paperboard Printing
However, for the printing equipment without drying device, the traditional method of powder spraying and small stacking has to be adopted. Powder spraying often leads to the decline of print gloss and the difficulty of laminating.Troubleshooting Of Sticking Dirt On The Back Of Paperboard Printing
At the same time, it will also pollute the production environment and equipment. We know that the back sticking is caused by the residual viscosity of the ink layer and the positive pressure on the substrate, so the back sticking problem can be solved as long as any factor is overcome.Troubleshooting Of Sticking Dirt On The Back Of Paperboard Printing
For packaging products, most of them are printed with thicker paperboard of more than 250G / m2, so the stiffness of the paperboard is higher than that of thin paper. Troubleshooting Of Sticking Dirt On The Back Of Paperboard Printing
Therefore, the semi-finished products after printing can be rotated 90 ° and placed vertically on the side, which reduces the positive pressure between each printed product, so as to avoid sticking on the back. The use effect is good. It is suggested that peers might as well try it. Troubleshooting Of Sticking Dirt On The Back Of Paperboard Printing
