Corrugated box printing

Offset first and then on - need automatic, semi-automatic machine and ordinary offset press - to adapt to a variety of 楞-type flexo direct printing - high-end multi-color printing slot machine - to adapt to a variety of 楞-type pre-printed - ——Need web printing presses, transformation of corrugated board production lines - adapt to direct printing of various stencil offset printing - special offset printing presses are needed - especially suitable for G, F sigma type As the corrugated box as a commodity sales volume increases, in particular The use of E, F, and G corrugated cardboard as packaging materials in packaging boxes and gift boxes for foods, toys, health products, and personal consumer products has become increasingly demanding and increasingly sophisticated. It is also getting higher and higher. In recent years corrugated cartons companies have launched a variety of high-end and multi-color printing presses, hoping to achieve more satisfactory results in printing 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.
