1 Under normal circumstances, whiteboard paper has many products for printing on the ground. Correspondingly, the amount of ink used is large. In order to reduce the phenomenon of pulling, the viscosity of the ink and the thickness of the ink layer should be strictly controlled during printing to prevent the back from being dirty.
2 Usually, a background color is printed first. The color of the background color can be diluted with the original ink color, or it can be consistent with the original ink color, and then the original ink is overprinted, which not only reduces the pulling phenomenon, but also solves the problem that the printing ink color is dirty once. The problem, after two print overprints, also increased the gloss of the print.
3 The surface of the whiteboard paper is rough, the texture is loose, the ink absorption is large, and the flatness is poor. Therefore, the printed version should first print the ground color, the dark color after the printing, the bottom color should be darker, the printing is light--the point, the ink color should not be too Big. If the white paper is flat, double-sided white paper, then. When printing the printed version, you must first print the dark color, and the amount of ink should be printed on the back. The back side is not sticky, and then the bottom color is printed on the thinner. This will make the printed product smoother. At the same time, pay attention to the ink balance and control. Good print version of the size of the water.
4 When printing more products on the ground, try to use the original barrel ink, do not add varnish, add some de-adhesives and anti-adhesive agents; do not add dry oil when the weather is hot. The printed version is often easy to stick on the back, often using a dusting method. Although the printing anti-stick dusty powder contains pure plant material, the dispersibility and fluidity are good. However, the use of powder spray directly affects the surface gloss of the printed product, making the ink print not bright, polluting the environment and affecting the precision of the printing machine.
