How to prevent dirt when printing whiteboard paper?

1 Under normal circumstances, whiteboard paper to print more products in the field, the corresponding speaking, the use of large amounts of ink, in order to reduce the phenomenon of pull hair, printing should be strictly controlled ink viscosity and ink thickness, to prevent the back of the dirty.

2 usually print a background color, the color of the background can be used to dilute the original ink, it can also be consistent with the original ink, and then overprint the original ink, which not only reduces the pulling phenomenon, but also solved a stamped ink stained The problem, after two overprints, also increased the gloss of the printed product.

If white paper is flat, double-sided paper, then. When the full-print version is on the ground, it must be printed with dark colors first, and the amount of ink should be printed in full, so that the back side is not adhered to, and then the background color is overprinted so that the print product finish will be better.

4 When printing more products, try to use the original barrel of ink, do not add ink, add some detackifying agent, anti-adhesive agent; do not add dry oil when the weather is hot. The full-print version of the field is often easy to stick on the back, often using a dusting method to solve. Although the printed anti-adhesive dirty dusting powder contains pure plant materials, the dispersion and fluidity are good, but the use of dusting agent will directly affect the surface gloss of the printed product, make the ink color imprinting is not bright, pollute the environment, affect the accuracy of printing machinery .
