How to EXPOSE AND DEVELOP A SCREEN FRAME 101A.
This video is Part 2 in our series following Coating Screens 101A.
Today, we’re using a BL1620 ExposureUnit w/UV Black lights. It has a simple on/off switch. You just have to add a
timer system; we use the timer on our phones.
EXPOSING
THE SCREEN FRAME
The first step is to have your artwork
ready. As you can see, we printed our artwork onto RhinoJet Film PositiveMaterial using an Epson 1430. We used this water-proof clear film material
because it provides a very dense film positive helping to ensure that no light
will penetrate the blacked out area.
Next, position the film positive
material onto the Exposure System.
Then, position the previously coated
screen frame over the film positive (the frame that we coated in the video Coating Screens 101A).
Add a pressure plate to ensure good
contact. We use one that is made of melamine board with foam (foam side down)
to ensure that the film is tight against the screen. We also add a few gallons
of RhinoMite adhesive to secure it even more.
Turn Exposure System on.
We know that it will take a 4-minute
exposure, because of previous test results. So…always test with a film positive
that has been pre-made for you using different filters. This will help you
narrow down variables due to type of Exposure System and type of emulsion
you’re using.
Once the screen is exposed, retrieve the
screen frame and get ready to begin the Developing Process.
THE
DEVELOPING PROCESS
The first step in the DEVELOPING PROCESS
is to move to the RhinoClean Washout Booth. Place screen in the booth and wet
screen on both sides.
Next, set Pressure Washer to wide fan
with low pressure (easily done with the RS 1500A) and with a smooth motion,
continue to wash frame – notice we’re working on the non-squeegee side of
frame. Be sure to flip frame and continue washing the other side.
Watch the design appear.
And, that’s it. You’ve just observed how simple it is to Expose and Develop a Screen Frame using the RhinoTech method.
Now, let the screen dry before you begin the Blocking Out process. And, because there are a few ways to do that, please watch for Part 3 in the series, Blocking out a Screen Frame 101A.
Thanks for watching the easiest way to
Expose and Develop a screen frame from RhinoTech. We look forward to working
with you.
