Development of Modularized Inline Coating System of Multi-color Offset Printing Press

摘要

A new type of inline coating system is designed and developed. The coating system can be mounted into printing press instead of blanket cleaner. An anilox roller and a sealed duct on the glazing oil transferring part for supplying and transferring the coating oil are introduced. A set of pressure adjusting mechanism is designed for changing the pressure between anilox roller and blanket cylinder, while a set of on-off impression mechanism is arranged to change the position of anilox roller and the on-off impression state. The press can print as normal when the coating system is dismounted. With this coating system, the press can coat prints with glazing oil. This system can be mounted in various type of printing machine. One new type of glazing technology named reverse coating can be achieved when it is mounted in multicolor press.
