I have a friend who owns a t shirt business and is interested in getting started with silkscreening. I went to school for graphics like 8 yrs ago and did some silkscreening but it was complicated. I was wondering if there is any equiptment out there for a small business that would be affordable and easy to do. Or is there any special paper you can buy for the printer to make a screen? We're only looking to do one color printing. Any info would be great! thanks

When I did screen printing, we didn't use paper stencils, instead it was a photo-sensitive emulsion. It's probably a little more expensive, but the results are drastically better. Unfortuantely, it also requires a sort-of dark room and a light table. What you have is an emulsion that is squeegeied onto the screen in a thin even layer (applied to both sides). It is light-sensitive, so as soon as it has been applied (it can be out in the light safely for 5-10 minutes while it is applied), let it dry (or blow dry) in a light-free room (about 45 mins to an hour air dried).
Design your print pattern any way you wish, but the final product needs to be black print on white paper or transparency. The black print should be the art you want printed, not the negative.
This is where the light tray comes in(i would suggest finding some professional consult on it's construction), probably the most expensive thing. Put your artwork down first, then the emulisfied screen over it (screen side down). Inside the frame, lay something down that will both cover the backside of the screen, and weigh it down (or both separately). expose it to the light for about 1/2 hour if the art is on paper, 15 mins if on transparency.
After that 1/2 hour is up, spray the screen with a garden hose or pressure washer (on LOW). The emulsion behind your black artwork should flush out, leaving you with a perfect stencil.
(to wash the screen completely, you'll need to buy emulsion remover as well, and will most likely need to be scrubbed out, and pressure washed).
Pro printers use these kinds of screens over paper stencils. Also, if you're printing t-shirts, or other washables, make sure you specifically buy inks made for cloth.
so yeah, costs besides paper and tshirts will be:
Screens (10 to 60 dollars)
emulsion: about 18 dollars, good for 3 to 4 screens. only efffective a month after opening.
Emulsion remover: about 15
Scrubbers (the same ones you'd use for floor washing)
The Pressure washer, and accompanying facility (or maybe outdoors) for washing, as well as the light table, and making a room lightproof will be your biggest costs to start.
Hope this helps...
