Stretching machine
In the printing process, the viscosity of the ink is increased to cause the paste, the main reason is that the ink solvent on the screen printing plate evaporates, resulting in an increase in the viscosity of the ink, and a phenomenon of sealing the net occurs. If the printed graphic area is relatively large, the ink on the screen printing plate is consumed more, and the paste phenomenon is less. This article will introduce you to the practice of stretching the mesh machine.
The stretcher is a special auxiliary machine for screen printing and plate making. It stretches the screen on the frame according to a certain tension, and is an indispensable machine for the plate carrier. Pneumatic and mechanical stretchers are popular in the market.

The curing light source is 6 UV lamps that are discharged side by side, and the power intensity is 60-80 W/cm for optical disc printing. When curing, after the first three UV self-adhesive printing lamps, the printed products should be blown in the cooling zone, then enter the curing zone of the last three lamps, and then blown with cold air, so that the desktop desk calendar is better.
