The highlight of printing value-added after printi

The finishing touch of value-added post press printing

the post press binding process undertakes the final decorative processing task of books and periodicals, which is related to the use value, reading value and collection value of books and periodicals. If there is no correct and firm connection and beautiful and elegant binding and processing, no matter how fine the printed matter is, it can not reflect its grade and value. Especially in the future printing, post printing is not only a post printing process, but also an important art processing process and a key link to greatly increase the value of the printing value chain. If the whole printing process is a one-stop process, then the finishing touch is the pen that can make the Dragon soar into the air. Only by positioning the post press in this way can we truly realize the importance of post press in future printing and the strategic value of investment in post press

In the printing industry, for a long time, enterprises' capital investment, technical strength and even site arrangement and other resource allocation have always given priority to prepress, then India, and finally post press. In the printing tripod, the force of one foot after printing is the weakest. Even for a period of time, many large and medium-sized book and periodical printing enterprises have compressed the bookbinding that does not make money, transferred the bookbinding operations to the bookbinding satellite factories distributed in villages and towns or rural areas, and concentrated funds and technical forces to strengthen prepress and color printing. In recent years, thanks to the gradient shift of the world's printing industry, the domestic printing industry has made great progress through the demand survey of enterprises and technicians. Driven by the strong market demand, it can provide a good guarantee for its working performance. Thanks to the development of digital printing and the wide application of information technology and digital printing process, it has also entered a period of excellent opportunities to strengthen its strength and strength after printing, And triggered a lot of new definitions of post press equipment. For example, wiring or multi-functional processing (using the printing machine to directly complete the paper pre press or post press surface finishing function, other post press processing, etc.) makes it difficult for us to define whether a device belongs to printing or post press. The traditional post press processing is mainly to complete the processes such as binding cutting, die cutting and bonding forming of printed matter, and incidental finishing and binding processing. In modern post press processing, the basic functions such as binding only account for a small part of the whole post press processing, and more processes are used for finishing and binding, anti-counterfeiting and other functions. The new definition of post press processing function and the new definition of post press processing technology, The new definition of the post press process has enabled more and more printing enterprises to re recognize the new position and role of post press in the whole printing field, and began to increase investment in post press equipment and software application. Most of the positions where the sample cracks may occur are at the time of strong force. In addition, domestic post press machinery manufacturers have provided suitable equipment with good quality and low price for post press processing enterprises, The 28 word policy for the development of the printing industry by 2010 put forward at the end of the last century has made the requirements of post press diversity and automation a reality, laid a foundation for further improving the level of post press technology and equipment, and provided unlimited business opportunities for the research and development of post press equipment and related software

Since the middle of the last century, China's post press technology has undergone three major changes: the first was the change from manual to mechanized post press in the mid-1950s; The second was the transformation from single machine to linkage in the late 1960s; The third is the transformation marked by digitalization since the 1990s, which has advanced to the international advanced level with the upgrading and diversification of single machine functions, linkage and online, making the post press processing, which has been almost forgotten in the printing technology for many years, begin to show potential rich added value, and gradually become a very important link in the whole printing process from the original auxiliary production process

in recent years, the following new trends have emerged in the post press in China:

first, the post press process is diversified and complicated, and gradually develops to high-end technology. The number of high-end books is increasing, various cover materials are changing with each passing day, and special post press processing technologies are emerging. For example, the whole book binding mode includes luxury binding, special-shaped binding, wireless binding or sewing binding hardcover, and soft hardcover with empty back processing without sticking cloth; There are more and more styles of the front opening of the cover. Some of the front openings are in the form of non folding, and the bleeding version is designed to be multi folded and require blood

second, the paper format and quantity should be in line with international standards. With the integration with international standards, the paper used for books and periodicals and the cover paper are also thickened and enlarged. High grade special paper is widely used. Wireless adhesive binding has become the mainstream binding method, and a variety of binding technologies and methods, such as Zoe binding and wireless Zoe proofreading, have emerged to encourage enterprises to make self declarations

third, the eight immortals of the post press equipment have crossed the sea, showing their respective powers. All kinds of automatic high-speed linkage production lines that develop synchronously with digital printing and match the production capacity have been widely used. If some digital printing is equipped with digital plate making, the book posts can be sorted in advance, and the printed matter can be directly bound into a volume without posts; Some automatic data input devices of page distribution mechanism can automatically identify hundreds of binding sizes of books and periodicals, control and monitor the actual operation status, and the image detection error system can randomly correct or eliminate incorrect page distribution; Some post press processing has been extended to the mailing part, which can be online inkjet printing address or labeling, and classified and packaged, and directly sent by the printing factory to the postal department. Post press equipment and auxiliary facilities with multiple automatic functions, which are suitable for small batch processing, make post press operation more convenient, more accurate, lower labor intensity, and save costs. For example, the full-automatic paper cutter that supports the external paper cutting program can directly transfer the PC program to the paper cutter through the computer interface, and there is no need to measure manually when cutting paper; The movable paper feeder can transfer the paper feeding mechanism from the printing machine to the folding process without reloading

the post printing process is becoming more and more diversified and complex, even so complex that people can do what they want, which is determined by the overall level and trend of social and economic development. The production of modern books or other printed and packaged goods requires not only durability and beauty, but also elegance and artistry, which can attract the attention of consumers

post press processing is not only a process, but is becoming an art. Semi finished products are like clothing materials here. Only after careful cutting and production by a skilled tailor can they become a high-end fashion. After printing, we should not only do our own work in this process, but also make up for some deficiencies in prepress and printing as much as possible, so that the printed products reaching consumers can meet the ideal requirements. At present and in the future, the development of post press technology will gradually match and synchronize with the development of new pre press technology and new printing technology, and will eventually lead the printing industry
