Troubleshooting Of Sticking Dirt On The Back Of Paperboard Printing

        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
