20"x24"UV Exposure
Unit UV Exposure Unit is an
important tool in screen making.
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.
Note: The maximum outer
sizes of your screen frame must be within 24.8" x 20.9"x1.5" (63*53*3.8
cm). If exceeded these sizes, our exposure unit cannot be covered well,
which will affect your exposing effect. |
