1, first of all should understand the mirror ink thin like water, printing skills is the key, when the printing speed is slow, on the one hand, thin mirror ink like water will leak down the screen, on the other hand, the mirror ink is easy to absorb the moisture in the air, after printing The resulting mirror effect is not good. For this reason, when printing, the mirror ink must be continuously and quickly printed after being poured into the screen plate. Only in this way can the smooth printing be performed. For example, blocking the net, ink printing can not go on, slag slag group on the screen.
2. The ambient temperature and humidity when printing mirror ink is very important, because the ink is easy to dry on the screen, so you can not screen printing under the air circulation, otherwise it is very easy to block the network, when the humidity is high, the mirror effect is poor, so When screen printing, avoid air flow and moisture as much as possible.
3, because the ink is thin as water, so you should choose high mesh screen, not only that, the hardness of the squeegee should be harder, more than 80o.
4, before the use of mirror ink must be fully stirred, so that aluminum powder and the resin to be fully mixed to ensure the appearance of the mirror effect, otherwise it will affect the mirror effect.
5, the screen tension is slightly lower, the network distance is also adjusted to some, and reduce the scraping pressure of the blade, otherwise it will destroy the formation of the mirror effect.
6, mechanical printing, the use of ink-jet knife can not use hard aluminum or stainless steel, but should use glial ink knife, to ensure that the screen printing mirror ink coating evenly, so that the mirror effect is consistent.
7. The mirror effect of mirror ink is related to the drying method. In terms of mirror effect, natural drying is not as good as heating and drying. Note that the heating temperature and drying time should be the same, otherwise the mirror performance and color saturation will also be There are differences.
