What is the effect of dusting methods on the quality of the coating?
Offset printing adopts a dusting process to prevent the printed matter from getting dirty, and a layer of fine particles is formed on the surface of the powdered ink. The coating film does not adhere to the ink layer at every place but binds to these powders to form a false-stick phenomenon, which seriously affects the quality of the coating film.
Therefore, the product to be covered should avoid the use of dusting technology, printed matter that has been dusted, and dry wipes on a dry basis with a dry cloth. The nature of the ink stickiness of the printed product is due to the ink. To solve this problem, the ink must be improved in the process, and the ink is added in proportion to 10% of the stickiness agent, which is very effective for preventing stickiness. After the ink is added with the viscose, it not only prevents stickiness, does not affect the hue and color saturation of the printed product, but also makes the ink layer brighter, the dots are clearer, and it is also more convenient for post-printing processing processes such as calendering, laminating, hot stamping. Wait. Viscosity adhesives can be used as an alternative to oily, dusty, and anti-adhesive dirty materials.
