Water mark fault and solution
Watermarks appear as uneven or wavy patterns on the printed product. This issue is mainly caused by low ink viscosity and slow printing speed.
Solutions for Watermarks:
Add original ink to increase viscosity.
Increase the printing speed appropriately.
Importance of Ink Performance in Addressing Printing Issues
As discussed, common problems in gravure printing are not only influenced by equipment and environmental factors but are also significantly related to the performance of the printing ink. The viscosity, adhesion strength, drying properties, re-solubility, and leveling properties of gravure printing inks have a substantial impact on the quality of printed products. When printing issues arise, operators should consider adjusting ink performance if adjustments to equipment and printing conditions do not yield satisfactory results.
