Special printing processes include:
1. Inkjet printing
Inkjet printing is an efficient and special printing method. It can be used in packaging industry production line to print production date, batch number and bar code quickly. Inkjet printing belongs to pressureless printing and uses a wide range of inks, so it can be used in various packaging products. This undoubtedly provides a great degree of freedom for the packaging production line. At present, there are many applications of inkjet printing are not known, how to make good use of inkjet printing technology is undoubtedly a hot technical issue, as long as we use it well, I 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 makes the quality of inkjet printing products have a qualitative leap. At present, some high-end inkjet printing products are close to the level of traditional printing in tone level, clarity, color saturation and so on. Some of its inherent advantages have been further developed, its printing speed has been accelerated, and the printing accuracy has been improved. With the combination of database, inkjet printing can be fully competent for variable data printing, which brings good news for the differential and personalized production of packaging printing. If the latest JDF production standard is adopted, inkjet printing equipment can easily be integrated into the digital production process of the whole printing plant, so as to achieve better equipment control and achieve higher production efficiency. The two main characteristics of inkjet printing are "printing on demand" and "personalization". These two characteristics can meet the emerging new demand of packaging market. Nowadays, narrow-band label packaging and printing production lines equipped with digital printing units are very common, and digital printing machines can be produced online with die-cutting equipment and post-press processing production lines to achieve higher quality and faster turnover speed.
2. Label Printing
Self-adhesive labels are commonly used materials in packaging and decoration industry. In China, at present, trademark printing is mainly based on offset printing. With the diversification and high-grade of trademarks, other printing methods are gradually joined.
Metal printing is a special printing method of printing materials. Because of its high cost, it is usually used for luxury packaging, so its profit is also higher. At present, the number of metal printing materials is increasing and new materials are emerging. No matter which material is used, its printing process is different from paper printing. Offset printing, transfer printing, screen printing and flexographic printing are mainly used in China.
3. Paper Packaging Printing
This field accounts for the majority of the share of packaging, decoration and printing, but also the application of special printing technology is less, but in this field we can also use innovative ideas to create more value. Because of the early development, carton printing and cardboard printing technology has been relatively mature, most printing plants have the production capacity of this product. Decorative patterns, patterns or words are printed on the package to make the product more attractive or illustrative.
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 kinds of anti-counterfeiting methods are commonly used in packaging, decoration and printing. Using laser holographic anti-counterfeiting technology, packaging products not only have an intuitive anti-counterfeiting effect, but also exquisite printing patterns shine in the sunshine, such as rainbows, which can attract consumers'attention. 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 very big. At present, many products adopt this anti-counterfeiting technology. This technology is a good way to increase 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 way of anti-counterfeiting. This technology also comes into being in response to people's demand for high-quality packaging products. This anti-counterfeiting technology utilizes a variety of printing equipment, various printing processes permeate each other, and various processes combine with each other, especially the introduction of some unique special printing methods. All these make the final product have strong anti-counterfeiting function. But at the same time, it also increases the cost of production and the complexity of production. The larger printing plants are more comfortable in applying this technology. Of course, the use of this technology will challenge the production level of the printing plant, which requires the printing plant to have high stability and precision printing equipment, a sound quality control and management system, and experienced skilled technicians, all of which are strong guarantees to improve the added value of products.
In some places, the special traditional printing technology has not been lost. Because few people have mastered the technology, these special printing technology has gradually become one of the means of anti-counterfeiting printing production, such as woodcut printing prints, because of its ancient and rare, it has also become a personalized high value-added printing products with national characteristics.
