Solve the problem of sticky problems in printed whiteboard paper

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 pulling hair, printing, ink should strictly control the viscosity and the thickness of the ink layer to prevent the back to take dirty.

Usually print a background color, the color of the background color can be used to dilute a little bit of the original ink, can also be consistent with the original ink, and then overprint the original ink, this not only reduces the pulling phenomenon, but also solved the problem of a dirty ink stamping After two overprints, it also increased the gloss of printed products.

White paper surface is rough, texture is loose, ink absorption is large, flatness is poor, so the full-print version should be printed on the ground first, dark after printing, the background color should be darkened, and the ink should not be too large. . 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. At the same time, pay attention to the balance of ink and water, control Good print imprint size.

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 .
