per printed printability addition to meeting the general requirements for letterpress printing printability, but also pay attention to the label printing related printability problems. Label letterpress printing process schemes, on the printability requirements are different, the process plan are the following, namely multi-color overprint prepress printing technology programs or bronzing printing after printing + lamination printing + stamping + film (1) The color and line printing. For color and line digital printing presses, ink requirement because of its larger, printing unit is required to be able to provide a large amount of ink transfer, but the sticker printing surface is smooth, greater density substrates, printing after the ink is not easy to develop the history of the conjunctiva, prone to smearing failure. In order to improve printability, in addition to the rational use of light quick-drying ink, but also pay attention to control the printing of ambient temperature and print speed. (2) bronzing. Stamping process in the self-adhesive label printing has been widely used, but to get good printing results, attention should be associated with stamping printability problems. If the printer is not set drying device, regardless of stamping process after the first printing, or using the first bronzing printing process, are due to the ink layer in contact with the foil stamping effect at the impact of the decline in printing quality. Therefore, the ink, in general, the drying should be set to the printer apparatus, and control the ambient temperature and the printing speed. If using quick-drying ink, you can print directly on the surface of gold foil after printing. When using a photosensitive ink, the printing ink due to the pre-stamping is fully cured, so it will not affect the stamping quality. (3) coating. Printing high-grade detergent packaging label products are often carried out after printing coating process, namely by pressing a transparent plastic film to stick to the printed surface, protect and increase the role of gloss. For the latter film products are generally not stamping process, because the coating surface treatment without polarity, if the city were bronzing printing and packaging, foil easily pasted on the surface of the film.
