For by many people cooperate together complete screen printing, only on the working procedure is responsible for the next working procedure, to do a good job of self-checking, self checking each working procedure, strictly the quality pass, in order to produce users satisfied with screen print.And screen printing, printing ink and printing in good match between these three is prerequisite to obtain a good print.In the process of mass production of screen printing, if you don't pay attention to a particular link is a bit, will bring a series of problems to the production, and this day is not solved, will have been plagued by production.
Plate quality directly determines the print quality, plate making of printing quality inspection, in plate under the premise of stable quality, however, due to the printer, also can't get ideal print, it will lead to greater waste, defective products or waste products.
Should be fixed before bulk printing printing screen into ink testing-run, check the layout of graphic copy of the ink layer thickness, specifications, level, ink, alignment precision, etc.If poor alignment precision, can be adjusted according to the frame at the front of the fine-tuning knob;If the ink color is not correct, check whether to use the wrong ink, and replaced immediately.If a bad example, use solvents to wipe forme graphic part, make the ink through the performance and wettability of substrates has been improved to a certain;If by order of harmonic levels have bigger difference, it should be replaced immediately screen printing.At four o 'clock in the printing process must pay attention to the following:
1, drying device of blade damage due to long-term use, and in some places run out of sync with the host, the print disorderly Zhang Xianxiang often cause paper shelves.At this time should be the load, immediately off at the bottom of disorderly zhang, had better not make the ink film surface, in order to avoid bad cause defective or waste.
2, often check sample.Immediately knew mark of ink with a clean cotton cloth wipe the screen.Most of this kind of circumstance is due to the plate with broken plastic or ink dry crust on the clogging caused by screen.If discover the ink unevenness or become pale, may be the ink viscosity is too big, should immediately stop the diluted with solvent ink viscosity, use gasoline wipe the layout of graphic part at the same time, prevent infiltration ink or blocking network, so that the continuous work.
3, often see rules.Due to space continuously back and forth movement when printing, the plate and frame by collision and vibration in the running back and forth, between small displacement occurs, will appear the phenomenon of inaccurate overprint, influence the appearance quality of the products.So often see rules, found in time, timely adjust.
Four, semi-finished products piled up neatly.In the process of the semi-finished products piled up, you must see to it that hang on the opposite side of the paper together.Otherwise the paper formed due to the gravity of itself on the bow, become warped on either side of the paper and not flat, was caused when the printing paper transfer is difficult, often arise Zhang Xianxiang cut off.Paper crib at ordinary times, can use cardboard mat flat, at the same time the paper crib often use points to the height of the adjusting knob to adjust the paper, so that the paper passed smoothly, printing process smoothly.
Therefore, only pay attention to the links affecting the quality of printing, to print out the fine print, increase yield, reduce the consumption increase benefit, make the enterprise in an impregnable position in the market competition.
