Corrugated box printing and processing

Offset direct printing - requires special offset printing presses - especially suitable for G, F type with the increase in the volume of corrugated boxes sold as merchandise, especially in food, toys, health products, personal consumer electronics packaging boxes and gift boxes Extensive use of E, F, G corrugated board as packaging material, and the design is more and more complex, more and more exquisite, and the requirements for the quality of printing and decorating are getting higher and higher. In recent years corrugated box enterprises have launched various high-grade, Multi-color printing presses are expected to achieve more satisfactory results for users in terms of print quality and accuracy. As far as the current printing methods are concerned, flexo and offset printing are the most widely used. There are direct printing, pre-printing, and printing and then printing on the processing methods.
The printing of domestic high-grade corrugated cartons has always used the method of offset printing first, and this method can ensure the printing quality. Therefore, more and more carton enterprises have automatic and semi-automatic facsimile machines, and even unprecedented results for offset printing machines. interest of. However, this printing method also has the disadvantages of complicated processes, low efficiency, high reject rate, and long processing cycle. To change this situation, flexo printing technology has made rapid progress in recent years, and various high-grade multi-color water-based printing has been opened. The introduction of slot machines has opened up new processing methods for high-grade carton printing, but the flexographic technology itself needs a familiar process, which makes the promotion of this method affected to varying degrees.
However, at present, the production of high-grade multi-color ink-and-ink printing presses has brought a large number of high-end product orders to the carton industry. Pre-printing can be processed using flexo and gravure printing methods. This method can guarantee high prices. Printing quality and overprinting accuracy, fast printing speed, high output, but need to rewind after the printing to form a roll print, and then corrugated board production line complex corrugated, so the cutting device on the corrugated board production line cutting precision and high requirements , And this method to adapt to the same large number of products, if a large variety of products, and a single species of small quantities, the use of pre-printed is uneconomical, because the cost of the acquisition of printing equipment and input equipment transformation is very substantial .
Several well-known international offset press manufacturers have been working on direct offset printing on corrugated paperboard for many years. This technology has gradually matured with the development of new types of fine corrugated cardboard, special blankets and inks. Since offset printing is the most popular and most mature printing method in China, the quality of printing is also widely recognized. It is believed that this type of direct offset printing will become a very strong marketing tool in China. However, at present, this new technology is only applicable to fine corrugated cardboard, and in particular, the stability of G-type and F-type corrugated cardboard is the best.
It is expected that these high-grade corrugated cartons (boxes) printing methods will coexist in the next three years. Depending on the size and pattern of the carton manufacturers, their respective market shares will change significantly.
