Technical Analysis of Direct Corrugation of Micro-Corrugated Cardboard

The direct offset printing technology for fine corrugated board is maturing with the development of new fine and fine corrugated board, special blankets and inks. Offset printing is the most popular and most mature printing method in China, and the quality of printing is also widely recognized. We believe that this direct offset printing method will become a very strong marketing tool in China. However, this new technology is 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 specification, wide application range, high strength of the carton, neat appearance, and favorable environmental protection, and is a main process for corrugated box printing. The global demand for this technology shows that it is increasingly accepted in offset printing and flexo printing. Even in the future, the print quality that can not be achieved by flexographic printing can be achieved in offset printing, because the letterpress printing has its limitations after all. The packaging industry continues to increase its 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 and gravure. This method can guarantee high printing quality and overprinting accuracy. The printing speed is fast and the yield is high. However, after printing, the web must be re-formed to form a roll print and then finely corrugated. The corrugated paperboard production line is used for the cutting of fine-cutting corrugated cardboard production lines. The cutting precision and requirements are therefore high, and this method is suitable for large quantities of products in the same batch. If the product variety is large, the batch size of the single product is not large. When using preprints, it is not ideal.

Corrugated carton industry in China is familiar with printing methods for printing corrugated and flexo-printed corrugated cartons, and the application is common, but it is relatively unfamiliar to preprinting and offset printing. However, with the gradual perfection of the market and the gradual maturity of the process, direct offset printing is based on the superior quality of its own four-color printing, coupled with the development of modern offset printing technology of the manufacturer in this field, direct offset printing of fine corrugated cardboard shows a good market expectation.

Offset printing can enter the field of direct color printing on micro-corrugated board, benefiting from the following two aspects: First, the successful development of new micro-corrugated cardboard has made important contributions to the realization of direct offset printing on micro-corrugated cardboard. Secondly, offset printing meets the need for the development of color printing on fine corrugated paperboard, while fine corrugated cardboard is also suitable for direct printing on offset printing presses, in which G-type and F-type micro-corrugated cardboard have good stability and can also be printed in the field. In particular, offset presses are now equipped with offset printing units and are no longer used for printing. This is also more conducive to the development of direct offset printing on fine corrugated board.
