the edges are sharp. say if i have an A, the middle part comes off with the rest of it. so you get nearly a triangle. same thing with an e. really, nearly anything with an "inside" to it. ive ended up doing some touch up with acrylic and it doesnt look too bad, and the acrylic wont wash out if it is set properly.
Thanks.
Thanks.

I have a couple things to say that may help.. First, I've used that emulsion and its not very good. You need to find one that is a little more light sensitive and exposes in light faster. You may need to spend $5-$10 more than you are now, but it's worth it. You can just speak with someone at whatever screenprinting supply place you go to, and they'll help you. Also, the longer exposure you do, the more light will get under the film and bounce between the film and the screen. This will cause exposing slightly under that dark part of the film that is not to be exposed. I think if you get stronger light to cut down exposure time, and a better emulsion you can prevent this. Try going up to atleast a 250watt bulb, but a 500watt would be ideal. You can get one at a hardware store. This will cut exposure time down to minutes rather than hours.
libprints: thanks for the advice.
i dont go to any screen printing supply store. i go to united art and education, just because i happen to work in there warehouse. unfortunately, it is the only place in town that offers screen printing supplies. also, the diazo is the only stuff that we sell.
so, going from there, does anyone have any advice on what kind of emulsion i should use? would i be able to order it online?
I will try a bulb w/ higher W.

Try calling Screenworks supply, they are very helpful. Just type in screen printing supplies on the net and a ton of companies will come up. It's really not very hard to find someone near you. And of course you can order supplies online, but if you don't know much about stuff than it is best to talk with a sales rep.
