Doe's any one knows where to buy a silkscreen (for fabric) exposure unit for home use on the entrnet?
I will be more than happy for a good link to it!
not used, but cheap.....here's how to make a cheap compression exposing system. It will get you going and be good for most bold graphics. You might have trouble with halftones, you really need a vacuum frame for that.
Buy a 1000 w metal halide lamp from a hydroponics outfit, or a 500w halogen lamp from the hardware store (not the best but it will work for home use)
-metal halide needs a transformer and a rectangular shade, universal bulb, mount it so the bulb is horizontal
-halogen, get rid of the filter glass and the cage.
Get a 2" foam pad slightly smaller than your inside of the screen
Get a piece of thick (1/8-1/4") glass the size of the inside of your frame.
get a piece of black cloth to cover the foam pad.
Mount the lamp over a work table 1.5x the diagonal distance of your screen
When you are ready to expose, place the positive face down on the back of the screen.
Place the glass over it.
lay the screen and the glass over the cloth and the foam pad.
Expose. (you need to test for time, do a step wedge with a nice detailed posi, move a black sheet 1" every 20 seconds. Your time will be anywhere from 1.5 minutes up to 7-8, depending on mesh color and stencil material)
metal halide needs to warm up first.
Don't look directly at the lamp when it is on.
