Special printing in the field of packing and decorating (below)

3. Label printing

Stickers are commonly used materials in the packaging and decorating industry. In China, the current trademark printing is mainly based on adhesive embossing. With the diversification and gentrification of trademarks, other printing methods are gradually added. In this field, the advent of advanced technologies has provided advanced solutions for printing systems. Narrow web presses with modular design and gearless transmission have been put into use. All leading equipment manufacturers provide hybrid production lines for labels and packaging printing. This hybrid line can be equipped with offset, emboss, flexo, silk screen, gravure, digital printing units and hot and cold foil units, making the hybrid line ideal for single-pass production of packages, cartons and labels. . This combined printing method also provides an anti-counterfeiting feature for the label. With the capability of label printing, printing houses can win more profits by improving the printing materials, deepening the printing process, and innovating printing methods, and developing label products with composite functions.

4. Metal products printing

Metal printing is a special printing method for printing materials. Because of its high cost, it is generally used for packaging of luxury goods, so its profit is also higher. At present, metal printing substrates are gradually increasing and new materials are emerging. No matter which kind of material is used, the printing process is different from that of paper printing. Offset printing, transfer printing, screen printing, and flexographic printing are mainly used in China. Some customers even require follow-up work such as molding after printing. This requires the printing company 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 customer satisfaction be met.

5. Paper packaging and printing

This area accounts for most of the share of packaging and decorating printing, but also the application of special printing technology in less areas, but in this area we can also use innovative ideas to create more value. Due to its earlier development, carton printing and cardboard printing technologies have become more mature. Most printing companies have the production capacity of this product. This area is a world of flexo printing. At the Shanghai All In Print show, some manufacturers pointed out that flexo printing is the future of packaging printing. Whether or not this formulation is accurate is a matter for the time being, but this trend is very obvious, although the current domestic situation is not the case.

An important factor affecting packaging printing is the trend of reduced print. Short-lived work is increasingly becoming the mainstream of orders. In this particular field, the flexographic printing process is also rapidly developing, thanks to the appearance of new photosensitive resin plates that support higher screen lines, enabling perfectly aligned CI printers and advanced digital flexo printing system. These factors make the quality of flexo reproduction better and the dot gain reduced. In the past 40 years, the development of flexographic printing has undergone tremendous changes. It was once considered as a simple process that is only suitable for printing plastic bags. Today, it can be used in offset printing, gravure printing, letterpress printing, and screen printing in the fields of packaging and label printing. Comparing with the United States. It is predicted that in the next few years, flexographic printing will occupy 38% of European packaging printing market share and 76% of North American packaging printing market share. By then, the proportion of flexo printing in packaging printing will reach 39%, while offset and gravure will drop to 36% and 15%, respectively.

In carton production, traditional sheet-fed offset printing is being challenged by flexo printing (on-line milling, finishing and sticking box units). The large-format, high-productivity printing machine, the slot machine, dominates the production of corrugated cartons. It requires the use of white backing paper and high-line screen printing plates to produce cartons, and prints high-quality color images to produce more cost-effective products.

Application and Development of Special Printing Materials

1. Special printing materials

In recent years, new achievements in the field of material research continue. Paper manufacturers are constantly deepening the additional functions of paper. They are trying to make paper become universal. If paper is used for packaging and printing, its strength properties and printability are key factors. However, it seems that the paper production technology has matured, and new varieties with breakthrough significance have not appeared in recent years. Fortunately, however, the paper product line has become more and more abundant and the classification has become more and more professional. There have been a number of new products with special functions. This poses new challenges for printing companies that want to create more value. They need to select the products that are most suitable for the production process of the factory according to the different needs of customers, and they are also the products that best meet the requirements of customers. At present, the strength of printing paper for packaging has been greatly improved, and even some papers have certain functional characteristics, which undoubtedly provides new options for printing plants.

At Shanghai All In Print, DuPont promoted their products Tyvek high-profilely. Tyvek is a trademark of DuPont's range of sheet products. These products are strong and durable, stronger than paper, and more versatile than fabrics. At present, Tyvek's packaging material is a standard in the desiccant industry worldwide. Due to its outstanding strength, durability, all-weather, adaptability, and ease of printing, this material also has a good applicability in the field of packaging and printing. When making paper bags or other paper packaging, consider using this material as an alternative. Compared to plain paper, it is not easy to tear, water resistant, and has a good printing effect. It is these advantages that greatly increase the added value of the product.

Progress in the field of materials science will never stop. I believe that the development of more new materials will bring us a more colorful world. Printing companies cannot put themselves outside this ever-changing world, but should actively devote themselves to In the application of new materials, use innovative ideas to create more value.

2. New type of special printing equipment

At the All In Print Shanghai Exhibition, a Dutch company launched a new type of flexo roller DTM, a self-adhesive foam roller. The use of this type of roller completely eliminates the use of sticker tape. It is a non-sleeve for flexo printing. The drum user brings a unique flexo-printing solution. This seems to be a small technological innovation, but we can see that even if the current printing technology has matured, there are still many things that can be improved, and these are the new profit growth points.

3. Future new technologies and development directions

The trend is determined by the market, and globalization of consumption will surely promote the rapid growth of the packaging industry. Consumers' demands for diversification will in turn make the packaging and printing industry more integrated with special printing to obtain more colors and better images. Higher quality and more personalized products. As technology advances, the competition between printing companies will become increasingly fierce. To survive in the future, you must have a future vision. As a printing factory, we must keep abreast of technological trends, pay close attention to market dynamics, actively develop our expertise, and win future productivity through continuous improvement of our own standards. The printing plant must understand its position, and the printing industry is the service industry. Therefore, printing is the service. To better serve the customer, you must master more service skills and use special printing technology to show your own characteristics. In this way, we can stand invincible in the long-term development.
