glossy ink Precautions

1 , since the mirror silver ink dilute water, it should choose a high mesh screen , not only that, squeegee hardness should be more rigid .
2 , mirror ink must stir before using it with aluminum powder mixed resin to fully ensure the emergence mirror effect , otherwise , masterbatch glow in dark the produce mirror effect .
3 , printing ink mirror when temperature and humidity are very important, because the ink on the screen easy to dry, so we can not screen in air circulation , otherwise very easy to block network , when the air humidity, mirror effect backward , so in the screen printing to prevent air flow and moisture as possible.
4 , screen tension slightly lower , the net transfer from also nearer, and appropriate pressure reducing scraping blade, otherwise the mirror effect will undermine the formation .
5, printing machinery , which can not be used to back blade with a hard aluminum or stainless steel , while the gum back blade should be used to ensure Photoluminescent Ceramic ink coating uniformity mirror , the mirror effect is the same.
6 , mirror effect mirror the way the ink is drying on the mirror effect in terms of heating and drying naturally dry less good , and note should be consistent with warming temperatures and drying time , otherwise the mirror performance and color saturation will differ.
7 , we must first understand the dilute water mirror ink printing technique is the key, when the printing speed is slow, on the one hand , dilute the ink will leak water shed mirror screen , on the other hand , mirror ink easy to absorb moisture from the air , after printing mirror effect was not good , for at the time of printing, the ink mirror inverted version must be continuous and rapid network printing , printing to complete successfully , that is, the printing side of the workpiece edge to check this rate, will give the effect of impact printing , such as blocking network , printing ink does not go on the screen slagging Orchestra.
