Exposing and Developing a Screen Frame is a vital part of the screen printing process. In this step-by-step instructional video (that follows Part 1 – Coating Screens 101A), you’ll be energized with the tips and technique to simply achieve this necessary step. To begin with, note that we are using a BL1620 Exposure Unit with UV Black lights. It has a simple on/off switch that, in combination with using the timer application on your phone, will enable you to perfect how to expose and develop a screen frame with finesse.

Exposing and developing a screen frame begins with an Exposure system.

EXPOSING and DEVELOPING the SCREEN FRAME. The first step:

The first step is to have your artwork ready. We printed our artwork onto RhinoJet Film PositiveMaterial using an Epson 1430 inkjet printer. We used this water-proof clear film material, because it offers 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 coated screen frame over the film positive (see 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. And, as you can see in the video, we topped it with a few gallons of RhinoMite Screen Frame Adhesive to secure it even more so.

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.

DEVELOPING the SCREEN FRAME:

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 and that simple. Now, let the screen dry before you begin to block out the frame. And, because there are a few ways to do that, please watch the next video, Part 3 in the series, Blocking out a Screen Frame – 101A.

Thanks for watching our video tutorials. The RhinoTech Team appreciates your interst and looks forward to helping you be wildly successful or even more so.
