Abstract

The invention discloses an overprinting method taking a rubber-coated center roller as a printing roller. Based on a following control system, the specific structure of the control system is characterized in that a PLC (programmable logic controller) is connected with a discharging frequency converter of a discharging part, a discharging traction frequency converter of a discharging traction part, a cooling frequency converter of a cooling part, a collecting traction frequency converter of a collecting traction part and a collecting frequency converter of a collecting part respectively; the PLC also can be connected with a PD3 motion controller by an Ethernet switch; the PD3 motion controller is also connected with a satellite intaglio center rubber-coated center roller, a satellite part one color servo, a satellite part two color servo, a satellite part three color servo and a satellite part four color servo in sequence. By adopting a control manner that the PLC and the PD3 motion controller respectively and independently control corresponding parts and are correlated, the problems of low overprinting precision and speed, poor control precision, and poor printing continuity and stability existing in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of printing equipment, and in particular relates to an overprinting method using a rubber-coated center roller as a printing roller. Background technique [0002] Printing equipment involves a wide range of areas. The printing machinery currently used in my country is mainly offset printing machines, unit-type gravure printing machines, unit-type flexo printing machines and satellite-type flexo printing machines. The printing effect of offset printing and unit-type gravure printing machines is It is the best, but solvent-based ink must be used, and because its unit-type structure is bound to produce a certain tension on the substrate, it is not suitable for printing on materials that are not resistant to stretching, and the satellite flexo printing machine Environmental protection, fast printing speed, but limited by the process, and its printing effect cannot be compared with gravure printing, etc., the peopl...
