What are the printing methods for corrugated paper
2019-04-01 15:40
Although it is the same as the "gravure gravure" in the gravure printing method, the paper gravure printing machine is different from the soft packaging gravure printing machine, and it is necessary to transfer the ink by applying a large printing pressure. Therefore, the plate cylinder and the impression cylinder are large. Heavy, it is a printing method for large-volume products.

Since gravure is a printing method different from flexo printing, the printing paper must have good smoothness. The gravure printing with a large amount of ink is thick and expressive, and compared with offset printing and flexo printing, it is a printing method which is highly evaluated in deep printing. In order to correspond to environmental measures that limit VOC emissions, it may be considered to correspond to water-based gravure in the future.

The so-called lithographic printing is offset printing. When it comes to corrugated offset printing, the past process is generally to first perform offset printing on a corrugated paper, etc., and then attach it to a single-faced corrugated paper. In 2000, due to the widespread use of G-type color corrugated paper, very thin G-type corrugated paper can be printed directly on the offset press.

This direct offset printing process can reduce the number of processes compared to the process of printing on cardboard and then bonding to a single-faced corrugated, so theoretically there are advantages in terms of delivery and cost, but the greater advantage lies in the G-type corrugated Offset printing can be performed directly, which can greatly reduce the amount of paper used.

The reduction in energy consumption during production becomes a reduction in costs and a reduction in CO2 emissions; a reduction in transportation energy consumption is associated with a reduction in transportation costs and a reduction in CO2 emissions. For example, digital cameras and other products use air transportation. If it is shipped to New York and the packaging is reduced by 10g, the air transportation phase can reduce CO2 emissions by 152.9g. The G-shaped ultra-thin micro corrugated packaging has high strength, thin thickness, small volume and beautiful printing. As a package that corresponds to the environment, it will be more noticeable in the future.
