As printing enters the stage of homogenization competition, printing companies must work hard in the post-press processing to achieve the differentiation of printed products; in the future, any lag in processing will cause the entire situation to be passive. As such, the post-press processing link in 2013 naturally became a new hot spot for printing companies to invest, and gradually showed the four development trends of personalization, high efficiency, digitalization and standardization.
Post-press processing is an important link in which all design concepts are finally reflected. As Pan Xiaodong, Secretary-General of the Shanghai Digital Printing Industry Association, believes that if the printing factory cannot achieve the ultimate in post-press restoration, then the product cannot be said to be a successful product. From this perspective, post-press must be further on the original basis Improve. As customers have higher and higher requirements for products and shorter and shorter production cycles, if they want to ensure product quality and improve product brands, they need to be completed by better post-press processing equipment. In addition, cost is also one of the reasons why people gradually attach importance to post-press development. Labor costs continue to increase, and post-press pressure is increasing for all operators, and there is an urgent need to further improve post-press. Therefore, printing companies began to pay more attention to post-press after paying attention to pre-press and after printing.
On the other hand, in recent years, printing equipment suppliers have often regarded the value-added printing that their equipment can provide as the focus of publicity. In fact, in the current printing market, the most added value for printed products is post-press processing. Therefore, printing companies are paying more and more attention to post-press equipment, and the requirements for post-press equipment are becoming higher and higher. Post-press surface treatment is an important technical means to improve the packaging grade and strengthen the competitiveness of the commodity market.
However, there is still a considerable gap between the domestic post-press technology equipment and the developed countries in the world, especially in the degree of automation, viability and adaptability of related technologies and equipment. From the perspective of technology and equipment application, China is still in its infancy. Like the technical problems of the laminating equipment, domestic equipment and adhesives still have some problems to varying degrees, such as deformation problems, durability problems, separation of film and base paper, etc. There is no ideal solution; there is also packaging The glazing and glue application technology and equipment of the printed surface have become the mainstream of packaging surface finishing technology and equipment abroad. The domestic mainstream is still surface coating, all of which are problems that we have to solve.
In order to better realize the value of printed products, printing companies have put forward new requirements for the development of post-press technology and equipment. At present, there are four development trends.
personalise. The industry gradually realized the necessity of paying attention to post-printing from the perspective of customers and actively exploring customer needs. Shanghai Lianghong Government Printing Co., Ltd. has been involved in packaging and printing since 2006, and has achieved success by paying more attention to customers in the production process. Rulianghong Printing is a toothpaste box printed by Colgate toothpaste. One of the parts has been improved to make this part have a glare amplification effect. Such products are particularly noticeable on the shelves. Therefore, Lianghong Printing was awarded the gold medal in the Colgate Global Printing Competition. In addition, when Lianghong Printing's team visited Philips, it was found that the production process of Philips products took 8 seconds in a post-press processing, making the entire processing line require more equipment and manpower, which became a production bottleneck; after returning to China Lianghong Printing has worked out ways to improve, and the final plan can complete the original task within 2 seconds, so it has also been recognized by Philips. Suzhou Dacheng Packing Products Co., Ltd. is also a good example. They added a lot of related processes before making boxes. For example, in the process of making corrugated boxes, they determined specific colors for each enterprise and printed them on its adhesive paper; Whether the product is genuine or counterfeit, as long as the packaging carton is pulled apart, it is equivalent to anti-counterfeiting technology.
Efficient. Efficient means that the operation is simpler and more flexible, and the preparation time of the print is shorter, which can avoid mistakes and improve production efficiency. Nowadays, with the increasing number of short-run prints on the market, highly automated post-press processing equipment is really needed in actual production. These post-press processing equipment are basically computer controlled to realize the digitization of the entire printing process. For example, BOBST MEDIA100â…¢A-2 automatic folding box sticking machine production line has a variety of additional functions, and has an automatic box packing machine and carton pre-feeding mechanism. In addition, this year's CHINAPRINT2013 Jinglun Quanxun's booth exhibited a device. After completing the digital printing and after another surface treatment, it can finally achieve the effect of unevenness like silk screen and colorful effect like lamination. Many processes that were originally made on different production equipment are all completed in one process, thereby improving efficiency.
Digitizing. Digital printing will become the fastest growing field in the printing industry, and the rapid growth of digital printing applications will inevitably drive the market demand for digital printing post-press processing equipment. Martini, MBO, Korbus, Holler, BOBST, Haoyou, etc. have all launched a line of post-processing processing lines that can be connected to digital printing equipment, including roll slitting, folding, collating, horse riding Ordering or gluing, three-sided cutting, die cutting, bronzing, creasing, punching, packaging and other processes can be completed online. Now the related supporting equipment for digital printing after printing has been formed, and a variety of models are available for end users to choose. In the future, with the further development and improvement of the industry, digital printing post-press processing will become a rapidly growing field. In addition, digital printing post-press processing is also one of the most environmentally friendly post-press processing methods. First of all, its flexible and highly automated features can realize single-copy processing without wasting a printed sheet or a little glue. Common volume problems. Secondly, each functional module of its connected processing equipment can control the operation or stop independently, use it when needed, and automatically stop the operation when not needed, saving energy and reducing consumption to the extreme.
standardization. Post-printing is a very complicated process, with great variability in technology. For example, there are as many as 14 binding methods for book binding, and there are also four or five commonly used binding methods. Although there are some common features in post-press equipment, there are also many types. From the current point of view, China has a large number of post-press processing, a large number of people engaged in post-press (about 35% of the total number of people in the printing industry), and the types and models of equipment used are complicated. It is reported that the paper width and book format used in China have entered the scope of international standards. The international paper size standards A and B series have been implemented. The paper consumption has been increased from about 52 grams to 70 grams, which is more than 7 billion yuan. Nearly 1/6 of the books and periodicals use coated paper, and this amount is also close to the international amount. China's paperback book binding technology has basically been eliminated, and the use of wireless glue binding has become the main method of connecting books and periodicals, which is in line with the international connection method. Advanced wireless binding and binding technology is adopted internationally, and China is gradually adopting it.
