Discuss the packaging and printing of alcohol
Alcohol packaging printing? The quality of wine sales is also very related to the packaging, because the wine is liquid, it is difficult to distinguish whether it is a good wine without tasting the mouth, at this time the role of packaging is very important, and there are many types of wine packaging, which is also determined according to the positioning of consumers. Wine packaging printing is traditionally based on offset printing, the use of thick paper type multi-color offset press, such as Heidelberg multi-color offset press, printing exquisite, fast, can print 0.6 ~ 1.0mm thick paper, the speed can reach 15,000 pieces / hour, printing wine boxes are extremely suitable. Offset printing is a relatively mature printing process, especially in screen tone printing, there is a set of standardized and data-based methods. However, in addition to mesh tone printing, wine packaging printing also involves a large number of spot color reproduction, such as a large area of red ground, gold (silver) color, pearlescent effect, etc. Due to the high requirements of spot color, especially spot color on the ground, and offset printing in the field, it is limited by the thickness of the ink layer, which is inadequate. At this time, you can use the double printing method of "first deep and then shallow", and try to avoid hollowing out text on the physical plate when designing, so as not to increase the difficulty of overprinting. At present, because the wine packaging materials are generally made of composite paper materials and printed with ordinary ink, there are problems such as adhesion, friction resistance and poor dryness. Therefore, manufacturers generally carry out UV technology transformation of offset printing machines, which fundamentally solves the problems of composite paper printing. Because UV ink greatly improves the physical properties of the surface of the ink layer, some packaging and printing enterprises have begun to use offset printing UV ink to print fine sand, gold, silver and other effects that are difficult to achieve in ordinary offset printing. Gravure printing has become another optional method for wine packaging printing due to the characteristics of high saturation, high contrast, high brightness, strong consistency, and high printing plate resistance. If the art design manuscript is larger, the ink color is thick, and the ordinary offset printing is slightly insufficient, and the gravure printing method is used, it can meet the needs. Another advantage of gravure printing is that it can print other substrates other than paper, such as printing on a laser security film first, and then laminating with cardboard to achieve another visual effect. Because gravure wine packaging is mostly ground, color blocks and lines, the requirements for color management in plate making are relatively not strict, and the printing process control is easier than offset printing and flexographic printing. The artistic effects of screen printing, such as frosting, refraction, ice flowers, and wrinkles, make the wine box packaging icing on the cake, which greatly stimulates consumers' desire to buy. In addition, because the brightness of the product increases after the use of screen uV local glazing, the three-dimensional effect is strong, and it is often used in the decoration of wine packaging color boxes. Flexographic printing is rarely used in the printing of color boxes for wine packaging, and some beer labels will use this printing method. It is believed that its advantages of environmental protection and hygiene will gradually be recognized and favored by the winery. Looking forward to the future trend of wine packaging printing, industry insiders believe that a variety of process combinations will become an ideal way for wine packaging printing, and combined printing can give full play to the characteristics of several printing methods. For example, when printing products with rich layers, offset printing can be selected; When printing spot colors and gold (silver) inks, gravure printing on a single sheet of paper can be selected. When a special decorative effect is required, screen printing can be used.
The combination of offset printing, gravure printing, screen printing and other three processes has brought a strong visual impact effect to the wine packaging color box, and with the post-processing process, the wine packaging color box has become a work of art that people can't put down.
