During the printing process, issues such as missed prints, speckles, and blemishes often occur. These are not only due to machine and process reasons, but may also be caused by electrostatic interference on the printed material, which directly affects the final quality of the printed material.
1.Burring
When printing graphic elements, solid areas, or large bold lines, ink splatter occurs, resulting in linear ink streaks resembling “whiskers.”

2.Graphic blemish
Static electricity causes dust attraction, causing dust particles and impurities to adhere to the film. After printing, this results in numerous uneven speckles appearing on the printed images.

3.Missed Print
During the printing process, static interference caused the graphics to fail to print, resulting in missing prints; when applying the base white ink, repulsion occurred, creating gaps.
4.Patterned markings
Uneven patterns with varying shapes appeared in the large-area printed sections, and adjusting the impression roller did not improve the situation.

5.teardrop-shaped droplets
During full-page printing, tear-shaped water droplets appear in multi-color overprinting, varying in intensity. This phenomenon is less likely to occur at slow speeds but becomes noticeable at high speeds.
