Glass screen printing is a process of glass processing, which is given by the silk master.There are manual screen printing and machine screen printing.
Introduction:We have seen many beautiful design flat glass, but I don't know how these patterns out. Glass processing factories usually have a silk screening room, the room with the other factory are separated, the door is closed, only a few screen printing master and some of the workers.Glass screen printing is a process with the glass processing, some glass need print design logo will need to enter the printing house, by screen printing on the draw master to give it a beautiful pattern, pattern is really printing master hand draw up?
Principle:According to the principle of silk printing, ink is printed to the surface of the plate glass, and then the curing of the ink is used to make the pattern firm and durable.The process is as follows:
The taut net→the paste→dry→sunburn→ development→dryness
↓
Plate glass→cut, edge→ clean dry→ printing

Workmanship:1. Inks: ink is used for silk printing and no ink.Ink is a lot of color, the ink is a silk - printing master must learn.2. Board: the board is designed for the design of the glass.First of the board on the screen of the photosensitive adhesive, combined with the film, strong light to make the design onto the net.Put the film under the net, then use bright light to expose the sensitive glue on the net, then rinse off the photosensitive glue that is blocking part of the film, and the pattern is made.3. oven roasted, yes, is to put the glass in the oven to bake, glass printed pattern, after the ink didn't kill quickly, if this time to pick up the glass will run into ink, it will damage pattern.After the oven, the ink will be dried out, the pattern will not be easily erased.4. Toughened furnace: why steel furnace?The silk print has a high temperature screen printing ink and low - temperature screen printing ink, high - temperature screen printing ink must need to be printed before the steel furnace.The ink is fused together with the glass surface, and you can't erase the ink.
