Micro-corrugated cardboard direct offset technology has matured with the development of new fine corrugated cardboard, special blankets and inks. Offset printing is the most popular and most mature printing method in China. The printing quality is widely recognized by everyone. It is believed that this direct printing method will become a very powerful processing method in the market. However, this new technology is currently only applicable to fine corrugated cardboard, especially G-type and F-type micro corrugated cardboard.
The direct printing of micro corrugated cardboard has the advantages of high production efficiency, low material consumption, low production cost, large product specifications, wide application range, high strength of carton, neat appearance and environmental protection. It is the main process of corrugated carton printing. The global demand for this technology shows that it is becoming more accepted in offset and flexo printing. Even in the future, the printing quality that can't be achieved by flexo printing can be achieved in offset printing, because the relief printing has its limitations. The packaging industry continues to grow in print quality requirements. The packaging design further promotes the offset printing of fine corrugated cardboard in the performance of excellent product transportation and external packaging.
Pre-printing can be processed by printing methods such as flexo printing and gravure printing. This method can ensure high printing quality and overprinting precision, fast printing speed and high output, but it needs to be re-rolled to form a roll print after printing, and the micro-corrugated corrugated cardboard can be used. The production line is re-corrugated, so the cutting precision and requirements of the cutting device on the micro corrugated board production line are high, and the method is suitable for the same batch of products, if the product variety is large, and the batch of the single variety is not large It is not ideal to use pre-printing.
China's corrugated box industry is already familiar with the first printing and then two types of corrugated box processing methods, and the application is also very common, but it is relatively unfamiliar for pre-printing and offset printing. However, with the gradual improvement of the market and the gradual maturity of the process, direct offset printing has a good quality by direct offset printing of micro corrugated cardboard by virtue of the excellent quality of its four-color printing and the development of modern offset printing technology by the manufacturer in this field. market expectation.
Offset printing can enter the micro-corrugated board. The direct color printing field benefits from the following two aspects: First, the successful development of the new micro-corrugated cardboard has made an important contribution to the direct offset printing of micro-corrugated cardboard. Secondly, offset printing caters to the development of color corrugated board color printing, and fine corrugated board is also suitable for direct printing by offset printing machine. The G-type and F-type micro corrugated board have good stability and can also be printed in the field. In particular, the offset press is now equipped with a flexo coating unit, which is no longer just for printing. This is also more conducive to the development of direct offset printing of micro corrugated cardboard.
