Fourth, the need to pay attention to the issue of vacuum aluminum printing paper printing 1, for the collapse of the product is easy to produce 180 ° C burst, a printing company has concluded a method of acceptance of the finished product, the molded product is folded forward 180 °C three times, reverse folding three times, or the same direction folded 180 °C five times No problems can be considered as qualified. This method has strong operability and can meet the requirements under normal circumstances. 2. Cracking of vacuum aluminum-plated paper occurs sometimes at the printing plant for two or three months. In order to avoid such accidents, it is best for the printing company to place it for a period of time before selecting new materials. Then test its stability. Such cracks that resemble the pattern of the turtle's back may be due to reasons such as inappropriate transfer of the aluminized paper coating layer or inappropriate ink used for printing. 3, after the occurrence of ink burst phenomenon, in addition to the toughness of the ink to adjust, but also to consider the glue used in the production of aluminum coating process, such as ink and glue components of the polar reaction, it is also prone to ink burst It is also wise to adjust the composition of the glue at this time. 4, in order to reflect the strong reflective characteristics of aluminum coated paper, you should use high transparency of synthetic paper POP ink or ultraviolet uv ink. Reasonable use of adjuvants to improve adhesion and gloss. The color adjustment of the base color is considered in the adjustment of the ink and the hue change after drying, so that the hue of the batch package is controlled within an acceptable range. 5, a reasonable arrangement of printing color sequence, a small area of ​​text and lines should be printed; dark color, small area of ​​the first printing and other designs, which is the premise of ensuring fastness. 6, pay attention to the temperature and humidity of the printing shop, this is because the poor absorption of aluminum paper, paper is easy to curl, if the environment can be printed on the temperature and humidity and material, ink, machine pressure, water and other factors control, this is Guarantee the consistency of the finished product and batch. 7, post-press processing to produce die-cutting plate according to the characteristics of aluminum-plated paper, the correct use of the mark and the bottom mold, so that when the package forming rebound is not, the mark line is not exposed. 8, for the wine performance requirements of the wine labels, blisters can be taken to identify whether the aluminized paper, water, soaking, traces of negative, so as to test the waterproof performance of the bottom paper, take preventive measures. 9. It is also very important to eliminate the odor of finished aluminized paper products. The drying time after printing can be lengthened, and the surface can be coated with water-based varnish, and forced ventilation can be added to the ventilation equipment and workshop at the printing site. 10. The storage time of vacuum aluminum-plated paper should not be too long, within the limit of two months. The first is to prevent the aluminum layer from oxidizing, and the second is that the aluminum layer on the surface of the paper will stick with the back surface, causing the paper surface to bloom. Five, summary Vacuum aluminum-plated paper not only looks gorgeous but, more importantly, it has anti-counterfeiting and degradable properties. It is an environmentally friendly product that meets international trends. The continuous development of tobacco packaging and printing requires all our practitioners to continuously improve their knowledge and skills, accept new things, and reasonably select and match production materials, in order to produce more refined and higher-quality packaging products.
