Raw materials are very important in order to provide the quality of the printed products of the corrugated display frame. First of all, we must work hard in management, strictly control the storage of raw materials, unqualified paper, ink, PS plate and other materials are firmly not in the warehouse.
(1) Quality requirements for ink: strong resistance to water, acid, alkali, alcohol, light and light; pure hue, bright color requirements, strong tinting strength; high transparency of ink, low hiding power; especially four-color overprinting The ink, the granules should be fine, and have a certain viscosity. It must have a certain degree of dryness. The offset ink is mainly dry oxidized and conjunctiva. When the two-color and four-color machines are working, high-speed printing is required under wet and wet conditions. Have a certain degree of dryness.
(2) Requirements for paper quality: It is required to have small stretchability and strong water resistance, and the ink absorption performance should not be too high; without pulling or removing powder, the texture should be tight, the paper surface should be smooth; the whiteness of paper should be high, acid and alkali Appropriate, requires the cutting size of the paper to be accurate; the offset printing paper should be hanged to adjust the appearance, so that the temperature and humidity of the paper are evenly distributed, consistent with the temperature and humidity of the workshop; offset printing uses minimum pressure and moisture, paper fiber direction and printing The direction of the paper should be the same.
In short, corrugated display racks are increasingly becoming an effective way to sell packaging. I believe that in the case of reasonable process, it will definitely be favored by consumers.
