Screen printing is not done by one person, but by many people working together.Only the previous process is responsible for the next process, do a good job in the process of self-inspection, self-inspection, strict quality control, in order to produce satisfactory screen printing.And screen, ink and printing these three perfect match is the prerequisite for obtaining a good print.Screen quality directly determines the quality of printing, printing is only the screen quality inspection, however, under the premise of screen quality stability, due to the printer’s care, the same can not get the ideal printed matter, but will cause more waste, defective or waste.
Before batch printing, should first fix the printing screen into ink, check the layout of graphic reproduction layer, ink color, ink layer thickness, specifications, overprinter accuracy.If the overprinter accuracy is poor, can be adjusted according to the table under the fine tuning knob;If the ink color is wrong, check whether the wrong ink, and immediately replace;If the ink is not good, solvent can be used to wipe the part of the screen layout, so that the ink through the performance and wettability of the substrate has been improved;If there is a big difference between the order and the level of graphics and text, should immediately replace the printing screen.The following points must be noted in the printing process.
1. Read the rules.Due to the plate frame in the printing back and forth movement, so that the screen plate and frame in the round-trip operation by the collision and vibration, a small displacement between the two, there will be overprinting inaccurate phenomenon, affecting the appearance of the product quality.So watch the rules, find them and adjust them.
2. Check the sample frequently.If ink is found on printed matter, wipe the screen with clean cotton cloth immediately.Most of this is due to the printing plate dirt, wool or ink skin drying block screen.If the ink color is found uneven or become shallow, may be the ink viscosity is too large, should immediately stop with solvent dilution of the ink viscosity, at the same time with solvent wipe screen version of the text and text part, prevent ink or block, in order to continue to work.
3. Stacking of semi-finished products.In the process of stacking semi-finished products, it must be neat and in the same direction.Do not put backwards or wrong.Material stacking error will affect the subsequent printing process.
Therefore, only pay attention to the links that affect the printing quality, can the printing of fine prints, improve the rate of finished products, reduce consumption and increase efficiency, so that enterprises in the market competition in an invincible position.
