I haven’t done any screen printing since last year. But I decided I want to make a few shirts as gifts. So I dug into the closet, and went through my screens. A couple have logos that I might want to print again sometime. But one screen had an image that I printed on a t-shirt for my nephew. So I pulled it out last night. I planned on reclaiming it this morning, but never got around to doing it. But tonight I took the time to clean it. I took it downstairs to the big wash sink in our utility room. I poured some of the stencil remover and brushed it around with a nylon bristle brush. Then I sprayed it with hot water. Very little of the emulsion came off. Well it has been on the screen for a long time! So I put some more stencil remover on the screen, and brushed it around. This time I left it to sit for a few minutes. Then I sprayed it again. This time most of the old emulsion came off. I sprinkled a little detergent on, and scrubbed it. I sprayed the screen again. I left the screen downstairs to dry. Hopefully tomorrow night I will be able to coat the screen.
Good to see you back in the screen printing scene mate

Hallo, not sure if you are still out there but I need some help. I am trying to screen print again after doing it for fun 24 yrs ago. I bought new emulsion, poly fabric & 250 w floodbulb BBA. Did several trials & the suggested 12″ above w/ lamp for 15 mins. Only a small little section came out. my transpariencies are very dark & new. The part of the screen that did not wash out look still a brown yellow, so not sure if underexposed or cooked brown??? No one in this town no anything about screening printing. called Speedball, they said raise lamp to 15″ for 15 mins. still no help. I’ve tryed a sample timing beginning from 4 mins to 15 mins, still parts sporically on the whole screen don’t wash out. I don’t know what else to troubleshot. Appreciate any comments or help, Monica

Hi Monica, check out my article here:
http://www.screen-printing-t-shirts.com/screen-printing-exposure-time-for-photo-emulsion-coated-screens.html
This will explain how to determine exposure time. Besides exposure time, you want to make sure you screen is evenly coated. Depending on how thick the coating is, the exposure time will change. I recommend using a scoop coater.

Let me know how this comes out.
