The holders can be easily installed because of the two-way clamps; besides, it can be adjusted in different heights and angles to satisfy different exposing demands. The equipped countdown timer makes it easier for exposing time controlling. The equipped black rubber subplate can reduce the ultraviolet reflection during exposing, which can guarantee a better exposure effect. * UV Exposure Unit is an important tool in screen making. At present, we have two patterns for your choice. Working principle: screen printing screens are coated with a light sensitive emulsion using a scoop coater. When the emulsion is dry, place a positive print of your image on the screen. Once you burn the screen, the emulsion that did not get any UV will wash out of the screen exposing the tiny pin holes. The surrounding areas that were exposed to UV will be cured. Hence the ink will pass through screen onto your substrate. * The equipped glass can guarantee a closer contact between the transparency film and the screen plate; besides, because of the glass sucker, glass taking is safer and much more convenient. The equipped transformer can change the 110V into 220V, which makes it much more suitable for Canada & US customer. The equipped universal switch plug can guarantee the two exposure unit working simultaneously. Equipped with package list and operation video; besides, we can also supply other technical supports.
