Bubbling stencil
Posted: Tue Jan 12, 2016 4:28 pm
Hi
I'm trying to expose a complex image on a 62t yellow
My light source is a single 1000w halogen, using a piece of clean glass to hold stencil tight with foam underneath the screen.
The film is cloudy A3 but has a crisp dark layer of ink
My emulsion is prochem dual plastisol/water based
I'm exposing for 9.30mins, usually no tacky feeling and stencil washes out under low pressure
Today I had a screen that wen very wrong, if anyone could tell me what the possible cause could be I'd be very grateful, I'll add a picture
