Matters needing attention in the screen printing process of the screen printing machine

The editor of the automatic screen printing machine manufacturer will explain to you the matters needing attention in the screen printing process of the screen printing machine：

For the screen printing completed by the division of labor and cooperation of many people, only the previous process is responsible for the next process, and the self-inspection and self-inspection of each process are done well, and the quality is strictly controlled, in order to produce screen printing products that are satisfactory to users. The perfect match between the screen, ink and printing printed by the automatic screen printing machine is a prerequisite for obtaining a good print. In the process of large-scale screen printing production, if a specific link is not paid attention to, it will bring a series of troubles to the production, and if this situation is not solved one day, it will continue to plague the production.

The quality of the printing plate in the screen printing machine directly determines the quality of the printed product. Printing is only a test of the quality of the plate making. However, under the premise of stable printing plate quality, due to the negligence of the printing workers, it is also impossible to get the ideal printed matter. , but will cause greater waste, defective or waste products.

Before batch printing, the printing screen should be fixed and poured into the ink for trial printing, and the ink layer thickness, specification, level, ink color, registration accuracy, etc. of the layout graphic copy should be checked. If the registration accuracy is poor, you can adjust it according to the fine-tuning knob on the front of the frame; if the hue of the ink is not correct, check whether the wrong ink is used and replace it immediately; The over performance and the wet ability of the substrate have been improved to a certain extent; if the tone and level of the image and text are quite different, the printing screen should be replaced immediately. The following four points must be paid attention to during the printing process:　　

The blades of the drying device are damaged due to long-term use, and some places are out of sync with the operation of the host, which often causes the phenomenon of random sheets on the paper rack. At this time, you should be quick with your eyes, and immediately remove it from the underside of the chaotic Z, so as not to make the ink film faces face each other, so as to avoid sticking and causing defective or waste products.　　

Check the proofs often. If the printed matter is found to be short of ink, wipe the screen with a clean cotton cloth immediately. Most of this is due to broken plastic film stuck to the printing plate or ink crust drying and blocking the screen. If it is found that the ink color is uneven or becomes light, it may be that the viscosity of the ink is too large. You should immediately stop the machine to dilute the viscosity of the ink with a solvent, and wipe the graphic part of the layout with gasoline at the same time to prevent the ink from bleeding or blocking the screen, so as to facilitate continuous work.　　

Watch the rules. Due to the constant movement of the plate frame back and forth during printing, the plate and the frame are subject to collision and vibration during the round-trip operation, and a small displacement occurs between the two, resulting in inaccurate overprinting, which affects the appearance quality of the product. Therefore, it is necessary to read the rules diligently, find them in time, and adjust them in time.　　

Semi-finished products should be stacked neatly. In the process of stacking semi-finished products, be sure to make the two sides of the paper sag and stack. Otherwise, the paper will form an upper bow due to its own gravity, and the two sides of the paper will be upturned and not flat, which will cause difficulties in paper transfer during printing, and often breakage will occur. If the paper stack is uneven, it can be flattened with cardboard. At the same time, the height of the paper stack should be adjusted with the adjustment knob of the paper separation mechanism, so that the paper can be transferred smoothly and the printing process can be carried out smoothly.

Therefore, only by paying attention to the links that affect the printing quality, can we print exquisite prints, improve the yield, reduce consumption and increase efficiency, so that enterprises can be invincible in the market competition.

The above is to say that the screen printing machine manufacturers need to pay attention to the matters needing attention in the screen printing process of the screen printing machine.
