Ecotex PWR - Pre-Sensitized Water Resistant Screen Printing Emulsion (1 Quart)

love this ready to go emulsion.

Good emulsion provides fine detail for my halftones. Very fast exposure time. Tough stencil that holds up to cleaning with a pressure washer after it has cured. I like that it is shelf stable. Have some screens that I coated 5 months ago, the exposure time was nearly twice as long, but still turned out great.

Don't follow the package timings, you'll be wasting your time and materials. The solution is very sensitive, and hard to manage, I got best results at 28 seconds with a 500 watt halogen light, and not the 8 minutes prescribed on the package. I suspect if I use the UV light, time are going to be less than 10 seconds.

Follow the curing time suggestions on the box. Works great for me.

I'm new to screen printing and when I first tried to use this emulsion, I failed miserably in so many ways. After much trial and error and so many messed up screens I have a system that works for me perfectly every time and I wanted to share it to hopefully save people some headaches. 1. Apply emulsion in a dark room, making sure it is smooth without drips. I use a headlamp with a red light setting so I can see. 2. Let the emulsion dry in a dark place where it will see no light. I usually go for 24 hours, but as long as it is not sticky to the touch it should be fine. 3. Print your image on transparency paper. I print it twice and put the papers together to make sure light does not get through. 4. Put the transparency paper on the side of the screen you will put against the shirt (or whatever you are printing on) and make sure the image is backwards so it will be correct when you flip the screen over. This is also a good time to think about the orientation and placement of the image on the screen so it will be easy to screen print later. Once the transparency paper is in place, set something clear over it, I use a piece of glass I got from a picture frame. Make sure your images are lined up and you did not bump them. 5. Put something black under the screen so you don't get reflection. 6. Using a 500 watt halogen yellow construction light (the standard yellow light you see everywhere) 18" over the screen and make sure it stays in place. Turn on the light for 4 minutes. 7. Before exposing the screen to any light put the screen under a shower or sink and get the areas wet where the images should be and let it sit for about 5 minutes to help it soften. Now you can run water over the screen and very lightly use your fingers to rub the areas to clear out the image. I do this on both sides until the image is very clearly clean of emulsion. I don't like to use a pressure washer, the sink works perfectly. That's it!
