Analysis on the development of packaging and print

Analysis on the development of alcohol food packaging and printing technology

compared with cigarette labels, wine packaging has some obvious characteristics. There are many varieties and grades of wine. On the whole, the printing of wine packaging is not as complex as cigarette labels. The printing process is mainly offset printing and several typical post-processing, supplemented by gravure printing and silk printing

industry insiders believe that the printing of wine packaging is still mainly offset printing, and the printing colors are mainly four-color and spot color. Labels for wine packaging are usually printed on coated paper, such as 80g/m2 and 128G/m2 high-grade coated paper. The printing of wine packaging box is mainly made of 350g/m2 white cardboard and white paperboard

traditionally, the printing of wine packaging is mainly offset printing. Thick paper multi-color offset printing machines, such as Heidelberg multi-color offset printing machine, are used. The printing is exquisite and fast. They can print 0.6 ~ 1.0mm thick paper, and the speed can reach 15000 sheets/hour. It is very suitable for printing wine boxes

offset printing is a relatively mature printing process, especially in eye tone printing, there is a set of standardized and data-based methods. However, besides eye tone printing, wine packaging printing also involves a large number of spot color reproduction, such as large-area red field, gold (silver) color, pearlescent effect, etc. Because spot colors, especially field spot colors, have high requirements for saturation and brightness, and offset printing in the field is limited by the approximate replacement of 2G absolute dry paste layer thickness with 6G extruded wet ink. At this time, the two printing method of "first deep and then shallow" can be adopted. During the design, try to avoid hollow words on the field version, so as not to increase the difficulty of overprint

now, because the wine packaging materials are generally made of composite paper materials and printed with ordinary ink, there are problems such as poor adhesion, friction resistance and dryness. Therefore, manufacturers generally carry out UV technical transformation on offset printing machines, which fundamentally solves the problems existing in composite paper printing. Because UV ink greatly improves the physical properties of the ink layer surface, some packaging and printing enterprises have begun to use offset UV ink to print fine sand, gold, silver and other common offset printing effects that are difficult to achieve

gravure printing has become another optional way of wine packaging printing because of its high saturation, high contrast, high brightness, or the use of ceramic materials on S3, strong consistency, and high printing resistance. If the art design draft is large on the spot, the ink color is required to be thick, and the ordinary offset printing is slightly insufficient. The gravure printing method can meet the demand. Another advantage of gravure printing is that it can print other printing materials except paper, such as printing on laser anti-counterfeiting film first, and then compounding with paperboard to achieve another visual effect

because gravure wine packaging is dominated by fields, color blocks and lines, the requirements for color management in plate making are relatively lax, and the printing process control is easier than offset printing and flexographic printing

the artistic effects of sanding, refraction, ice flowers, wrinkles and so on of silk printing make the wine box packaging icing on the cake, and greatly stimulate the purchase desire of consumers. In addition, because the brightness of the product increases after using silk UV local glazing, and the three-dimensional sense is strong, it is often used in the decoration of wine packaging color boxes. Flexographic printing is rarely used in the printing of wine packaging color boxes at present, and some beer labels will use this printing method. It is believed that its advantages of environmental protection and sanitation will gradually be recognized and favored by wineries

looking forward to the future trend of wine packaging printing, insiders believe that a variety of process combinations will become an ideal way of wine packaging printing, and combined printing can give full play to the characteristics of several printing methods. For example, when printing products with rich levels, offset printing can be selected; Sheet fed gravure printing can be selected for printing, such as color and gold (silver) ink after capacity reduction. When special decoration effect is needed, silk printing can be used

the combination of offset printing, gravure printing and printing has brought a strong visual impact to the wine packaging color box. Combined with the post-processing process, the wine packaging color box has become an unforgettable art

in the process of pursuing efficiency and economic benefits, new technology research and development has become the driving force for the sustainable development of enterprises. There is reason to believe that domestic packaging and printing enterprises will continue to innovate, and innovative technologies and processes will appear in the field of wine packaging and printing
