The development of innovative technology of wine packaging printing

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 colors and spot colors. 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/M ~ white cardboard and white paperboard

prepress design

the development of prepress technology has improved the packaging and decoration quality of goods. As we all know, in addition to paying attention to its own quality, packaging is also one of the keys to the success or failure of its marketing. The design of wine packaging is not only the idea of art designers, but also the modern design should fully consider the application materials, printing methods, post press processing, environmental protection standards, as well as the filling methods and wine labels of the manufacturers. After understanding the precautions and characteristics of the rubber tensile strength testing machine, the later pasting process should be taken into account. Therefore, designers should have extensive knowledge and sufficient information. The traditional graphic design software in the past can no longer meet the current market demand for packaging and printing products, and the prepress design software is constantly updated. For example, Esko graphics company launched an application software deskpack, which has strong professional design functions and is a prepress production tool application software

printing method

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. Since spot colors, especially field spot colors, have high requirements for saturation and brightness, offset printing is limited by the thickness of the ink layer that can protect power semiconductors from external factors such as moisture, dust and temperature changes when printing on the ground. 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 due to its high saturation, high contrast, high brightness, 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; When printing spot color and gold (silver) ink, sheet fed gravure printing can be selected. When the viscosity of the container decreases with the increase of shear stress and special decoration effect is required, 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

post press processing

according to different wine packaging designs, post press processing includes film covering, hot stamping, embossing, local glazing, die cutting, etc. due to the rapid development of printing materials in recent years, film covering is divided into bright film, matte film, laser film, laser anti-counterfeiting film, etc

in recent years, embossing technology has been constantly innovated, and it is widely used in gold card paper and aluminized paper. By stamping words or patterns through the press, we can obtain good visual effects, and also have good anti-counterfeiting effects. At the same time, some packaging and printing enterprises with strong technical strength have developed some new technologies. For example, in the packaging and printing of medium and high-end wine boxes, the post press processing technology of "hot stamping + embossing" has emerged, which integrates the original two independent processes of "hot stamping" and "embossing" into one process. One process can produce hot stamping, raised or recessed words and patterns, which look beautiful and generous, and play the role of the finishing touch. This technology reduces the process, improves the production efficiency, and thus saves costs. At present, this technology is being popularized and applied

at present, a new technology has emerged in the field of post press processing, which also integrates two independent processes "die cutting" and "pressing concave convex" into one process, namely "die cutting + pressing concave convex", and completes two traditional processes by using one-time pressure of the equipment. This technology requires that under the same pressure conditions, it can not only play the role of die cutting molding, but also achieve the concave convex effect. This innovative technology can improve the utilization of equipment and reduce the printing cost of wine packaging color boxes

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 push through the old and bring forth the new. In the field of wine packaging and printing, samples will be produced and connected with fixtures to realize innovative technologies and processes
