In recent years, the label market competition is becoming increasingly fierce, and the user's requirements for label printing quality are constantly improving. At the same time, the use of narrow flexographic printing technology not only expands the company's business scope and production capacity but also accumulates rich experience in prepress processing, plate selection, screen plate production, and flexographic printing technology.
First of all, in prepress processing, many customers' design orders are based on offset printing or gravure printing. If the original is printed by flexographic printing, there will be a lot of quality problems, such as the color is not in place, the level is not obvious, and there will be hard edges. Therefore, to solve such problems, timely communication with customers is very necessary.
Secondly, the selection of flexo plates must also compare three. Printing enterprises need to cooperate with a number of plate-making companies to fully understand the use of plate materials, the production of screen plates, the transition of layers, the increase of dot compensation, plate expansion, and other issues. This is not only conducive to production but also can control the quality parameters, avoid human interference and reduce the occurrence of faults.
Thirdly, due to the particularity of label printing, narrow flexographic printing equipment has outstanding characteristics compared with convex printing and other types of flexographic printing equipment. Narrow flexographic printing equipment not only has simple operation, high printing quality and operation efficiency, strong combination, can make more kinds of products, and has more competitive power.
1. Selection of color order
Flexographic printing label of its graphic part mainly to the field, lines, text-based, using the substrate materials are mostly paper, aluminum foil, plastic film, self-adhesive and so on. When water-soluble or solvent-based ink is used to print absorbent substrate material, the material will puff up after drying by infrared hot air, which will affect the overprint accuracy. The color plate with a large area should be printed in the back unit, because the substrate after absorbing a large amount of ink is dried by infrared, and the puff change of the field unit is larger than that of other units. If you have to print the field part in the front color group, you can consciously make up for the loss caused by the substrate material inflation.
