The main points of operation of curved printing
During mesh printing, in order for the curved surface printing to proceed smoothly, the following three requirements must be observed.
1.The centerline of the squeegee must pass through the normal to the surface of the substrate.
2.The substrate must be a rotating body.
3.The substrate or printing plate must be able to move.
pay attention when presswork, the frame should be moved at a constant speed, and the pressure of the squeegee should remain unchanged. During the printing process, the substrate cannot be loosen to any direction, and the substrate should be kept rotating at a constant speed. When mesh prinitng, in order to make the color of the printed surface clear, it is necessary to keep the printing plate and the printing surface with a certain gap, and the printing substrate should be easy to print and collect.
Curved printing is compared with flat printing , surface printing is generally difficult to press out of ink. For example, a thin-walled plastic container will be deformed if an impression is applied to the printing surface. In this case, first press the air into the container to prevent deformation during printing. If the printing plate is made of wire mesh or chemical fiber mesh, the ink is easily pressed out.
