Special printing technology and materials

special printing was closely connected with packaging printing at the beginning of its birth. Through the classification of packaging printing materials, we can clearly see that most of the production methods of packaging printing materials belong to printing that is far from meeting the needs of the market. Therefore, packaging printing and special printing blend with each other both conceptually and practically. In recent years, with the progress of science and technology and the growth of various professional needs, special printing technology has achieved unprecedented development, penetrating into all fields of packaging and printing, thus forming a huge market

according to the survey data of "it strategies" in 2005, the total value of the global printing industry is $702billion, of which the total output value of packaging and printing products is $325billion, accounting for 46% of the total value of the printing industry. In Asia, the annual output value of the packaging industry is 148billion US dollars, with a growth rate of 8% - 12%. In China, this trend is more obvious. According to the statistical data of 2004, the annual output value of packaging and printing is 98.1 billion yuan, firmly occupying the first place in the market structure of the printing industry with a 36% share. It can be seen that packaging and decoration printing is an important force that cannot be ignored in the printing industry

in this era of rapid development of information technology, traditional commercial printing and publishing printing bear the brunt, and have been strongly impacted by the new media represented by the Internet. The gradual rise of online publishing and electronic reading has replaced people's traditional reading habits to a certain extent. Although this subtle influence is unlikely to cause big waves in the short term, its trend is still relatively obvious

in contrast, the packaging and printing industry is much less impacted, and can benefit from the technological revolution in the digital age. Therefore, it can be said that the future of printing lies in packaging printing. Packaging and printing materials are mainly divided into the following categories: hard packaging, corrugated packaging, soft packaging, folding cartons, paper bags, labels, metal cans, sanitary products packaging, multilayer kraft paper bags, plastic containers and glass containers. From so many classifications, it is not difficult to see that this industry is involved in an extremely wide range and is closely related to our daily life

in order to better serve this rapidly growing industry, equipment and equipment manufacturers have invested a lot of money and manpower to develop more valuable technical solutions. Only in this way can we meet the requirements of today's society for diversity and personalization. More importantly, only by constantly developing new technologies can we find new profit growth points for the industry and produce high value-added products

application and development of special printing technology

special printing has always occupied an unshakable position in the field of packaging printing

1. Inkjet printing

inkjet printing is an efficient special printing method, which can be applied to the packaging industry production line to quickly print the production date, batch number, bar code and other contents. Because inkjet printing belongs to non pressure printing and uses a variety of inks, its substrate range is very wide, which can be all kinds of packaging. This undoubtedly provides a great degree of freedom for the packaging production line. At present, many application fields of inkjet printing are unknown. How to make good use of inkjet printing technology is undoubtedly a hot technical issue. As long as we use it well, we believe it can bring us unexpected results

with the continuous progress of digital technology, inkjet printing has also developed rapidly, and some technical problems have been perfectly solved, which has made a qualitative leap in the quality of inkjet printing products. At present, some high-end inkjet printing products are close to the level of traditional printing in hue level, clarity, color saturation and so on. Some of its inherent advantages have also been further developed. Its printing speed is accelerated and the printing accuracy is improved. Combined with the database, inkjet printing is fully capable of variable printing. As long as it is tenacious and indomitable, it brings good news to the differentiated and personalized production of packaging prints. If the latest JDF production standard is adopted, inkjet printing equipment can also be easily integrated into the digital production process of the whole printing plant, so as to achieve better equipment control and higher production efficiency. The two main features of inkjet printing are "printing on demand" and "personalization". These two characteristics can meet the emerging new needs of the packaging market. Nowadays, narrow label packaging and printing production lines equipped with digital printing units are very common, and digital printing machines can be connected with die-cutting equipment and post press processing production lines to achieve higher quality and faster turnover speed

at present, compared with traditional large-scale printing equipment, inkjet printing equipment has lower cost and more convenient use and maintenance. With less investment, it can win future production capacity. Undoubtedly, it is a powerful weapon for the production of high value-added products. At the same time, the application of a large number of inkjet printing equipment in packaging printing also provides favorable conditions for the standardized production of packaging prints

2. Anti counterfeiting printing

it can be said that in the field of packaging and printing, anti-counterfeiting printing plays a vital role. If ordinary products need a significant product logo, then many high-end products have to need a perfect anti-counterfeiting system. This is the need of manufacturers and consumers. Therefore, anti-counterfeiting printing is widely used in the printing of packaging and decoration products. With the continuous improvement of people's brand awareness and the strengthening of intellectual property protection, it is believed that anti-counterfeiting printing will have great market prospects. At present, the general situation is that many ordinary printing manufacturers do not have the ability of anti-counterfeiting printing, so they have to outsource the order. In many cases, this order is more profitable than a simple printing order

common anti-counterfeiting methods include: laser holographic anti-counterfeiting, special ink anti-counterfeiting, plate making and printing process anti-counterfeiting, special paper anti-counterfeiting. At present, the first three anti-counterfeiting methods are commonly used in packaging, decoration and printing. Using laser holographic anti-counterfeiting technology, the packaging products not only have an intuitive anti-counterfeiting effect, but also the exquisite printing patterns shine in the sun, with gorgeous colors like a rainbow, which can attract the attention of consumers. Therefore, this technology is very suitable for packaging printing. Using special ink anti-counterfeiting technology is a low-cost method. Because in general, it does not need to add additional equipment, and the transformation of the existing printing process is not great. At present, many products use this anti-counterfeiting technology. This technology is a good way to improve the added value of printing products, because it has less investment and quick effect. The application of anti-counterfeiting technology in plate making and printing process is a comprehensive anti-counterfeiting method, which is also born in response to people's demand for high-quality packaging. This anti-counterfeiting technology uses a variety of printing equipment, a variety of printing processes penetrate each other, and a variety of processes are combined with each other, especially the introduction of some unique special printing methods. All this makes the final product have strong anti-counterfeiting function. But at the same time, it also increases the production cost and production complexity, and larger printing plants are more handy in the application of this technology. Of course, the use of this technology will pose a challenge to the production level of the printing plant, which requires the printing plant to have high stability and high-precision printing equipment, a perfect quality control and management system, and experienced and skilled technicians, all of which are powerful guarantees to improve the added value of products

in some places, special traditional printing techniques have not been lost. Because fewer people master the technology, these special printing techniques have gradually become one of the production means of anti-counterfeiting printing, such as woodcut printing prints. Because of its antiquity and rarity, it has also become a personalized high value-added printing product with national characteristics

as a branch of special printing, in the fight against counterfeiting and counterfeiting, anti-counterfeiting printing technology is changing with each passing day, and some new technologies even surpass the traditional printing, such as radio frequency identification (RFID) technology. It is unrealistic to require the printing plant to master these core technologies in a very short time, but as a printing plant, the oil delivery valve handle must rotate for one week to keep up with the development of the times and master the technical trend. Only in this way can we win a broader market and have the ability of sustainable development

3. Label printing

self adhesive labels are commonly used materials in the packaging and decoration industry. In China, the current trademark printing is mainly self-adhesive embossing. With the diversification and upscale of trademarks, other printing methods are gradually added. In this field, the emergence of advanced technology provides advanced solutions for the printing system. The narrow web printing machine with modular design structure and gearless transmission has been put into use. All leading equipment manufacturers provide hybrid production lines for label and packaging printing. This hybrid production line can be equipped with offset printing, embossing printing, flexo printing, silk screen printing, gravure printing, digital printing units and hot and cold foil printing units, which makes the hybrid production line an ideal choice for the single channel production of packaging, cartons and labels. This combined printing method can also provide anti-counterfeiting function for labels. Printing plants with the strength of label printing can win more profits by improving printing materials, deepening printing technology, innovating printing means and developing label products with composite functions

4. Metal products printing

metal printing is a special printing method of printing materials. Due to its high cost, it is generally used for luxury goods (2) considering the packaging of the range of the experimental machine, so its profit is also high. At present, metal printing materials are gradually increasing, and new materials are emerging. No matter which material is used, its printing process is different from paper printing. Offset printing, transfer printing, silk printing and flexographic printing are mainly used in China. Some customers even require subsequent work such as forming after printing, which requires the printing factory to adjust the printing process in time according to different printing materials, introduce simple mechanical processing equipment, and formulate a reasonable production process. Only in this way can we meet the requirements of customer satisfaction

5. The field of paper packaging printing

accounts for the majority of packaging and decoration printing. At the same time, it is also a field with less application of special printing technology, but in this field, we can also use innovative ideas to create more value. Due to its early development, carton printing and paperboard printing technology has been relatively mature, and most printing plants have the production capacity of this product. This field is the world of flexo printing. At the Shanghai all printing exhibition, some manufacturers pointed out that flexographic printing is the future of packaging printing. We don't care whether this formulation is accurate or not, but this trend is very obvious, although the current domestic situation is not so

an important factor affecting packaging printing is the decreasing trend of printing volume. Short version activities are increasingly becoming the mainstream of orders. In this special field, flexographic printing technology is also developing rapidly, thanks to the emergence of new photosensitive resin plates that support higher line count, CI printers that can achieve perfect registration and advanced digital flexographic printing systems. These factors make the tone reproduction quality of flexo printing better, and the dot enlargement rate is also reduced. In the past 40 years, the development of flexographic printing has undergone great changes, which was once considered only suitable for
