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 adjustment of the offset paper feeding section,the double sheet control of the offset printing machine,and the distance between the paper feeding pad and the surface of the impression cylinder.
When the gray cardboard is printed,the air volume of the paper feeding nozzle and the paper blowing nozzle of the paper feeding part should be adjusted accordingly.For the paper nozzle,the paper feeding nozzle needs to be replaced with a larger diameter or larger.Thick rubber band.
By the coupling pin between the removed paper feed roller cam and its shaft or the roller on the swing rod,the purpose of the roller not swinging and smooth paper feeding is achieved.
When the gray cardboard is printed,the double control or gap of the offset printing machine should be increased accordingly.For the distance between the side gauge and the front gauge,the distance between the paper tongue and the paperboard should be increased correspondingly.The distance from the surface of the impression cylinder and the paperboard to the transfer pad should be slightly increased and kept at a certain distance.
