In foreign countries, rubber head cleaning device was installed on the transfer machine earlier, which improved the printing quality. In the printing process, because the ink on the surface of the rubber head can not be completely transferred to the print, the ink remaining in the resin will gradually change the edge of the image on the surface of the rubber head, causing a decrease in clarity. There are two ways to solve this problem. One is to improve the deinking ability of the rubber head and the other is to install a rubber head cleaning device. The plastic head cleaning device is characterized by an increase in the action printed on the plastic paper during the return of the offset head than the ordinary offset press, and the residual ink on the surface will be removed.

For multi-color printing, the improvement of the accuracy of overlay printing by adding cleaning devices is obvious. If multi-color overprinting involves dot replication, then the phenomenon of dot expansion will be significantly curbed. At present, the domestic printing machine has been developed in the direction of full automatic, rubber head cleaning function has become popular, and manufacturers can explain. Transprinting technology is a less elaborate special printing technology and does not need to pay too much attention to the details of the printing process.
