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 printing 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, which is an indispensable machine for the plate carrier. Pneumatic and mechanical stretchers are popular in the market. Of course, there is also a type of stretcher, called a fully automatic hydraulic netting machine. This type of pump net machine will have a relatively high degree of automation, and the application process shows great efficiency, high quality and low consumption. Many features, such as less labor, are getting more and more attention from users, and are the main equipment for high-precision stretch nets. Stretching machines are currently available in the market: manual stretcher and pneumatic stretcher; among them, manual stretcher is divided into bead type and collet type. The manual bead type stretcher has become the first consideration in the printing industry due to its relatively low cost. The hardness of the printing blade is HS65-75, and the printing effect of the squeegee and scratch card is better. In printing, the ice ink is intermittently solidified, and the printing speed of the printed advertisement on the conveyor of the curing machine is 25 to 35 m/min. 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 blow with cold air, so that the desktop desk calendar is better.
