â‘ Generally, there are many solid products printed on whiteboard paper. Correspondingly, the amount of ink used is large. In order to reduce the fluffing phenomenon, the viscosity of the ink and the thickness of the ink layer must be strictly controlled during printing to prevent the back from getting dirty.
â‘¡ Usually print a background color 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 overprint the original ink again, this not only reduces the fluffing phenomenon, but also solves the problem of printing ink color stickiness The problem is that after two printing overprints, it also increases the gloss of the printed product.
â‘¢The surface of whiteboard paper is rough, the texture is loose, the ink absorption is large, and the flatness is poor. Therefore, the background color should be printed first, and then the dark color should be printed. The background color should be adjusted a little deeper. Big. If the flatness of the white paper is good, and double-sided white paper, then. When printing the full version of the field, you must print the dark color first, and the ink volume should be printed enough, as long as the back side is not sticky, and then overprint the background color thinly, so that the printed product will have a better finish. At the same time, pay attention to the balance of water and ink The size of a good plate-making print.
â‘£When printing more products on the ground, try to use the original barrel ink, do not add ink oil, add some debonding agent and anti-sticking agent properly; do not add dry oil when the weather is hot. Printed version of the field is often easy to stick on the back, often used powder spraying method to solve. Although the printing anti-sticking dust powder contains pure plant material, the dispersibility and fluidity are good, but the use of powder spray will directly affect the surface gloss of the printed product, making the ink color imprint bright, polluting the environment, and affecting the accuracy of the printing machinery .
