Plastic woven bag ink printing and printing adhesion and its solution

Date:2018-08-13 Click:
The cause of the failure: 1. Sticky bag after the printing stack or after the rewinding. 2. The printing speed is too fast and the rewinding is too tight. 3. The drying device is not in the right angle or malfunctions. 4. The ink is too dry. 5. The storage stack is too heavy. 6. The temperature is too high and the cooling is not complete or the ink is not heat resistant. 7. The ink is too thin and transparent. Remedy: 1. Adjust the printing speed and check the angle of the drying device. 2. Improve ink dryness (or increase ethanol 90+ ethyl ester 10% mixed diluent). 3. When stacking, the stacking should be less or the storage load should be lighter. 4. Reduce the temperature of the workshop or warehouse (open the window to make the air convection, etc.), and change the heat-resistant woven bag ink. 5. Add the original ink to increase its viscosity or add a solvent with a small molecular weight and volatilize the solvent quickly (recommended by the ink factory).
