4, a two-component ink: common epoxy or polyurethane means that although there are many other species. Dual fluid systems are often in the timber is to save energy in the
most sensible choice, its high quality of the coating, but mixed inconvenient. Also according to the product's use should be selected, if the product could be used in outdoor, but also note
there is some flexibility, so the choice of an aliphatic hydrocarbon as the main urethane ink. Now a two-component epoxy resin ink market is almost the same as baking enamels performance, but
not good enough formability.
5, ink additives: Like other inks, by screen printing metal inks may also contain additives, which is produced when the intake of a small amount of chemical agents to improve
the performance of the ink film, and some can accelerate the curing or initiating curing, while others can be the bubble burst, uniform quality ink, reducing the possibility of the
conjunctiva. Manufacturers pay additives mixed with the ink, depending on the recipe together, printers are required to dilute the ink suitable for printing consistency. Fourth, Printing:
screen printing quality, ink layer thickness and the thickness of the screen, the ink viscosity, hard charging, angle blade plate making process are closely related.
1, the wire version and location: aluminum material three-point boundary positioning. When color printing, the first light-colored print, then printed dark.
2, the distance between the plate and the substrate is 1-2 mm from the size of the screen and select relevant, good stretch nylon mesh, stretches, generally 2-3 mm.
3, blade with urethane rubber sheet, a hardness of 70-75 degrees, a thickness of 8-9 mm, a blade angle of 70 degrees is appropriate printing, blade speed should be uniform
linear motion.
4, appropriate protective films: label after printing in order to avoid cutting and trauma caused during shipment, to be affixed to the surface of the transparent
pressure-sensitive adhesive protective film on the back of double-sided tape to paste.
5, cutting: cutting with a small bed, side molding can be used to locate or positioning hole punching.
