drying hot air in offset — One problem with offset printing is that the ink is usually not sufficiently dry after printing, and therefore direct further processing/finishing of printed sheets is not possible. If cardboard is not sufficiently dry after printing, several problems can arise: In offset printing a sufficiently dry sheet that can be further […]

maintenance of offset printing rollers — For cleaning the rollers for offset printing it is recommended: 1. Use a water miscible wash to remove the top layer of solvent-soluble and water-soluble particles from the nap of the roller. 2. Use a non-grit roller paste to remove the insoluble particles. 3. Finally, wash a second time with […]
