Koyu Trading Co., Ltd., a city in the center of Guangdong Province, has recently developed a printing technology that uses sponge liners under printing plates to greatly improve the printing quality of corrugated cardboard. When corrugated paper is printed, if the printing pressure is too high, the paperboard will be damaged, and the pressure will not affect the printing quality. This method of depositing by the sponge company reduces the printing pressure on corrugated cardboard and effectively controls the expansion of outlets. And when printing, the ink is more even, and the embossing point surface is more adaptable, so that the printed pattern is more clear and the color is brighter.
This method can also reduce the deformation of the printing plate and prolong the life of the printing plate. It also has a unique compensating effect for the old printing press whose printing roller beats too much.
