Abstract

The invention discloses a gloss paint overprinting method of a flexo printing machine. The method is implemented through a gloss paint overprinting system which structurally comprises a printing roller servo driver, wherein a color mark sensor is arranged in front of the printing roller servo driver, the printing roller servo driver is connected to a controller through a switch, and the printing roller servo driver is connected with a printing roller motor and provides power for the printing roller motor. The method includes the steps that firstly, a color mark block occurring periodically is looked for on a printed product, when the color mark sensor detects a signal, the signal is transmitted to the controller, and the controller controls the printing roller servo driver to perform corresponding adjustment. The method solves the problems that in the prior art, overprinting cost is high, and equipment is complicated.

Description

technical field [0001] The invention belongs to the technical field of flexographic printing machines, in particular to a varnish overprinting method for a flexographic printing machine. Background technique [0002] As we all know, printing is currently the most important processing method for product packaging. Vigorously developing green packaging and printing is a concrete manifestation of the development of circular economy in the packaging and printing industry. It is the essential requirement of comprehensively coordinating the concept of sustainable development. A powerful move in harmony with nature. [0003] As traditional gravure printing machines pollute the environment, the country has higher and higher requirements for the emission standards of the exhaust gas of printing enterprises, and people's awareness of environmental protection is getting stronger and stronger, traditional gravure printing machines will eventually be flexographic printing. machine repla...
