I have a small screen i need to do a very small print for. Screen is about 12 inches by 12 inchs.

I do not have a place to burn the screen (ie. a real lamp). Is it possible to burn a screen with photo emulsion using the sun, or a home lamp??? Please let me know how I would do it.

Also, once i do actually put the paint on the material, am I supposed to heat cure it? How do i do that with a regular iron?

Thanks much....appreciate all your help peeps.

Sure you could. UV light cures the emulsion.
The only question is how long to leave it in the sun..... With a light its been tried and true.

I really hate to rain on your parade but I dont believe your going to find a quick easy answer. Even with a commercial vacume exposure unit exposure tests must be done to find the correct exposure time when changing mesh colors, materials and or emulsions... If you google "How to screen print" you should be able to find quite a few sites that will give you an understanding of the Basics to help you start out with... it will also explain the inks envolved with textile printing with this under your belt we may be more able to answer your questions that you will still or might have....
Heres one to get you started http://www.silkscreeningsupplies.com...34/page/513584
Good luck with your project.... Chuck

Hey Cposch
Heres some info that might help.
When i first started, i used a commercial Halogen 500w lamp. You know, the Work Lights.
I used it at 13" from the Emulsion surface, for 12 minutes.
I cosistently got great results form this distance. No wash out around the edges, and no over cooking the screens.
Remember to put some glass on the artwork to keep it flat, { it does get hot form this distance} A local glass shop can get you a 20" x 24" sheet of NON uv blocking glass for less than 10$
And yeah, wash it out with cold water for about 5 mins, and if its sunny, i will prop it up outside, and in 10 mins shes ready to tape up.
Also if its night time{ my fave time to work} i just lay it on the ground under a flash unit to speed up the drying time.
Hope this helps.

As others have said, possible but unreliable.

Yes you are.

If you're using plastisol: you don't. If you're using waterbased ink: you let the ink air dry (you can speed it up with a hairdryer, etc. if you want), then iron over the print for the time the manufacturer recommends, normally supplied with the ink.

we use two 500w halogen lamps 12" high and leave for 7 mins, and never have any screens mess up!
