A customer mentioned a problem, why to powder in the process of making color box? Where did this powder come from? In the printing process of paper, in order to make the ink dry as soon as possible, the ink will be accelerated by dusting technology. Generally, only one side of the printed product needs to be dusted to dry, and the other side does not need to be dusted. However, during the dusting process, dust is not easy to control, so often do not need to spray powder on the other side of the printed products will also stick to a lot of dust, and these dust for the coated products of the larger impact, easy to cause the coating fastness of the reduced, the problem such as the membrane. Let's talk about why the color box is not pink. Before covering the printed paper with plastic film, a number of brush rollers are usually installed to remove the dust on the surface of the printed product. In order to improve the dust removal rate, a negative pressure suction device is also installed The cleaned dust is directly sucked away to avoid the second adhesion of the dust on the printed products. If it is an automatic laminating machine, in the front of the machine are installed with efficient powder removal equipment, in the paper before glue through the device can often achieve the role of powder removal. Color box production process in addition to powder is to cover, to prevent dust in the printing color box surface attached, so that the color box will be more beautiful.
