The printing glazing machine is divided into a glazing machine and a printing glazing machine. Domestic glazing machines are generally operated in a single machine, the processing speed is slow, and the quality is not high. For this reason, it is often necessary to perform calendering. The large-scale offset printing manufacturers in foreign countries mostly use the printing optical link machine to improve the speed and quality of the glazing. The printing optical ensemble is the development trend of glazing machinery.
           The basic form of the optical linker printing on the printing optical link is to use the dampening device of the last printing unit of the sheetfed offset printing machine to modify the original ink supply system, and then to print the paint; or the last printing unit in the offset printing machine. A coating roller device is attached to the blanket cylinder to apply the glazing paint to the rubber and then to the printing product.
