key words: combined printing plate printing and packaging

since entering the 21st century, with the improvement of people's material living standards, consumers have higher and higher requirements for the quality of packaging and printing products. In order to remain invincible in the fierce market competition, packaging printing should be endowed with artistic, decorative, gorgeous and exquisite features that are not easy to slip on the premise of ensuring the quality of printing. Obviously, it is difficult to make prints have so many characteristics at the same time under the previous single printing process conditions. In the case that a single printing method is difficult to meet these increasingly complex product needs, a linear combined processing method that can complete multiple printing processes at the same time in a printing process, combined printing, has become a competitive choice for printing manufacturers

advantages of combined printing

combined printing refers to a printing process in which two or more different printing methods are combined to complete different printing and even post press processing, that is, a printing method in which multiple printing processes and post press processing are completed by one-time paper (or plastic film and other printing materials). Simply put, it is a flow production line composed of various types of printing and post press processing units. In combination printing, processes such as flexo printing, embossing, offset printing, gravure printing, hot stamping, cold stamping and indentation can be mixed. At present, the most common combined printing units usually include printing, flexo printing, embossing and hot stamping units

combination printing is the product of the continuous development of printing technology. Compared with the traditional single printing method, the combined printing process of using multiple printing methods to write once again has the advantage of successfully participating in the construction of a large number of key pipeline projects

1. it makes up for the defects of various printing methods and improves the printing quality. Combined printing technology combines various printing methods, makes full use of the advantages of a single printing method, learns from each other's strengths, and can meet the various quality requirements of consumers for packaging printing products as far as possible, effectively improving the printing effect

2. Add decoration and artistic effects to the packaging and printing materials to make the printing materials distinctive. Compared with conventional printing methods, combined printing has the advantages of high production efficiency, low loss rate, small total equipment investment, small floor space, less operators and so on

II. Functions in printing and packaging combined printing

plate printing is one of the oldest printing methods. It can be printed on various printing materials, such as plastics, textiles, metals, glass, ceramics and other materials. Printing is widely used in commerce, advertising, packaging, art, construction, publishing, printing and dyeing, and electronics. In short, any shaped object, regardless of its size, thickness, soft, hard, curved surface and plane, can be printed. So plate printing is also called universal printing. In the middle and late 20th century, printing has developed rapidly, which is mainly reflected in the variety and high-quality quantification of printing materials, the automation of printing equipment, the renewal of technology, as well as the application of computer technology such as computer pre-processing system, color desktop typesetting system, digital computer plate making, electronic imaging, etc. it has gradually developed into a modern printing technology that keeps pace with flexographic printing, offset printing and gravure printing. The emergence of combinatorial printing technology has expanded a broader space for the development of block printing. Due to the special nature of printing, it can make up for some deficiencies of other printing methods. The effective combination with other printing methods can improve the printing quality, increase the decoration and artistic effect, and make the printed matter distinctive. In combination printing, printing mainly undertakes the following functions: increasing the attractiveness of printed products. In the design of air permeability effect, it is necessary to use very thick colors or luminous inks; It needs to show embossing, sanding and other effects on cigarette packs or cosmetics packages; Using light variable temperature printing ink to improve the anti-counterfeiting function of valuable tickets and trademarks. In addition, printing combined with other printing methods can also print labels used in harsh environments, such as battery labels, paint labels, etc; Printing products that need to emphasize product brand and logo, such as drug description labels, injection labels, etc; Printing packages that need to obtain metallic effects such as gold and silver; Printing simple and exquisite packaging with decoration effect, such as using printing to print large areas of field and anti white characters, instead of printing fine words; Print scraping awards, such as all kinds of lottery tickets and other securities

III. plate printing in packaging combined printing

combined printing includes different printing methods, which together with other processing processes achieve the purpose of adding value to printed matter. Mr. Steve leibin, sales manager of m a t I K North America, listed three requirements that packaging printing materials need to meet: higher printing quality; Better display appearance; As well as the requirements for the "unlabeled" appearance of products, reverse printing or the use of metal/fluorescent labels. Leibin believes that printers combine the unique advantages of each printing method to provide a stronger visual impact for label printing. For example, compared with flexography, flexography can provide higher ink coverage and higher color intensity; Using plate printing, the printing factory can remove the white pigment on the transparent white sticky material; Using gravure printing, printing plants can use heavy metal or fluorescent ink, bright oil or thermal ink to achieve special effects

at present, in combined printing, the combined application of block printing and other printing methods mainly includes the combination of block printing and flexographic printing, the combination of block printing and offset printing, and the combination of block printing and digital printing

1. combination of plate printing and flexographic printing

in the combination process of flexographic printing and printing, plate printing makes up for the prominent effect that flexographic printing is difficult to achieve by virtue of its unique advantages such as printing ink layer thickness and ink layer can be adjusted at will. At present, the rotary printing unit with high printing accuracy and the combination printing of flexographic printing machine have played an important role in the field of packaging anti-counterfeiting printing. The combination of rotary printing and flexo printing has the following characteristics

① improve the quality and creativity of printing products and enhance the attractiveness of products. If you need more expressive products, as long as you adopt the air permeability effect design, and then use thick colors or luminous inks, you can achieve the ideal effect; It is suitable for delicate packaging, decoration and printing. It can be used in the packaging of cigarettes, drugs, cosmetics and other commodities. Through technical treatment, it can show the effects of embossing, sanding and so on

② large area of field and anti white words can be printed. The anti-counterfeiting function of tickets and high-end trademarks can also be improved by using light change and temperature change printing inks

③ metal effects such as gold and silver can be obtained on the substrate. What should be paid attention to in the use of pendulum impact testing machine?. Such as book covers, exquisite greeting cards, etc

④ using this combined printing method to print suggestive signs for specific groups (such as the blind, etc.) can achieve an ideal effect. By combining embossing, printing and flexo printing, stamping, die cutting and other processes to form an assembly line for label printing production, we can obtain a variety of effects on the same product and rapidly improve the quality of prints. This combination printing method is simple and economical. Judging from the market demand at home and abroad, this combination printing method will have a good development prospect in the label printing industry

2. The combination of plate printing and offset printing features thick ink layer and full ink color, which also provides favorable conditions for offset printing to enter combination printing. The white ink surface after plate printing, like the surface of white printing materials, can be easily printed on its surface by offset printing, showing high-quality printing effect. The combination of offset printing and printing is the preferred process for many high-end packaging, especially high-quality cigarette packs, and can even meet the needs of printing high-end labels. In the combination process of printing and offset printing, large-area field color blocks can be printed by using the advantages of thick and uniform printing ink; By using the advantages of offset printing, four colors and complex lines can be printed, which can significantly improve the printing quality and effectively enhance the anti-counterfeiting effect. The combination of offset printing and printing can show artistic and creative effects such as frosting, ice flowers, crystal, wrinkles, refraction, etc. it is the preferred process for many high-end packaging, especially high-quality cigarette boxes and some specific products (such as securities). In addition, the combination of offset printing and printing can even be applied to aluminum plate printing. The combination of offset printing and printing can create high profits for enterprises, so it is popular and develops rapidly

3. combination of printing and digital printing

digital printing has the advantages of saving resources, saving costs, short business cycle and high operation efficiency, and can also deepen the degree of intimacy with customers. It is the backbone to support the development of printing at home and abroad. Since its birth, digital printing has been famous for its "variable quantity, variable information, and printing from one copy". With the increasing demand for printing on demand, variable data printing, personalized image reproduction and other printing, the application space of digital printing is expanding rapidly

plate printing has diversity and can be printed on almost all kinds of substrates. The depth and flexibility of color are unmatched by digital printing. The combination of digital printing and silk printing can just make up for this defect. At the same time, it can effectively solve the problems of centralized printing volume and urgent delivery time, and further expand the development space of digital printing and printing


from the demand of domestic and foreign markets and the current situation of the packaging printing industry, the combination of printing and flexo printing, the combination of printing and flexo printing and embossing, offset printing and embossing and other combinations are more economical combination printing methods at present and in the future, in which printing plays a crucial auxiliary role. There are still many technical and material problems in combinatorial printing technology that need to be further explored and improved. With the increasingly personalized and diversified packaging and printing products, combinatorial printing will be widely used in the packaging and printing industry
