What should be paid attention to during the printing process of gray cardboard
Gray cardboard is an environmentally friendly packaging material produced from recycled paper.Gray paperboard has the following points in the printing process,such as the conditioning of the offset paper feeding section,the double sheet manipulation of the offset printing machine,and the spacing between the paper feeding pad and the surface of the impression cylinder.
When printing on gray cardboard,the air volume of the paper feeding nozzle and the paper blowing nozzle of the paper feeding part should be adjusted correspondingly.The nozzles and paper feeding nozzles of the paper separation should be replaced by larger diameters or larger.Thick rubber band.
The coupling pin between the removed paper feed roller cam and its shaft or the roller on the swing rod is removed,so that the roller does not swing and the paper is smooth.
When the gray cardboard is printed,the double control or the gap of the offset printing machine should be increased accordingly.The spacing between the paper tongue of the side gauge and the front gauge and the paperboard should be correspondingly increased,and the paper pad should be correspondingly increased.The spacing between the outer surface of the impression cylinder and the paperboard and the transfer pad is slightly increased,and a certain interval is maintained.
