Can someone tell me what went wrong with this screen? Its the second screen we've done and I'm not exactly sure what I did wrong? The words stared to smear right after the pressure washing. Thanks. I'll attach the pic...I hope!
From the bubbling to the right of the text It appears that it took too long to wash out.... if you spray even the most perfectly exposed screen long enough it will wash out like that and the film will also blister as yours has....
As for why it took so long to wash out I dont know.... film not opaque enough, to little pressure during washout... However you say it did it after washout??? then perhaps you need to do a post exposure...you might be under exposing to get a clean washout then the standing water continues to dissolve the emulsion... A post exposure will finish locking the emulsion molecules.... Good luck with your screen making....
I don't have years of experience or a trouble-shooting background, so take this with a grain of salt. If I had to guess my guess would be this:
You coated the screen with too much emulsion, especially at the edge. You dried the screen with what is now the right half in this photo at the top, and it dripped down (this happens, and isn't necessarily a problem). After exposure you pressure washed the screen. The sections with large pieces of dried in emulsion from the drips offered more resistance for the pressure washer to catch on and got caught (plus they may not have been hardened all the way through to the screen) - it blasted the drought pattern effect into the screen. The smearing around the words is either from semi-wet emulsion (wasn't exposed long enough) or from the pressure washer. Pressure washers can blast out emulsion even without stencil remover (it won't clean the screen, but it can ruin one if you weren't intending to clear the stencil). If you're just washing out unexposed emulsion after a screen exposure you don't need to use a pressure washer.
Maybe I'm way off, but it might be an idea if you're getting desperate.
From the looks of that photo. Looks like you washed out the screen, and it seems that it was set sideways to let dry, and some kinda liquid or something dripped down and caused it to crack and in the end messed up your image.
In anycase it's time to reclaim that one and do it again.
Almost looks like you didnt degrease the screen well enough or rinse the screen enough. If anything is left on the screen before coating youll get funky results.
So its safe to assume that if we are leaving it to dry for 24 hours we are in good shape? I think I may have over rinsed using my pressure washer.
an average dry time at normal room temp is around two hours if you put a fan on it..... a normal cheap box fan will do just fine... Just aim it across the screen instead of directly at it...
Look at the screen and when it is dry it will have a dull matted look instead of the shine you started with....
It looks as if something got on the screen before coating and interfered with emulsion sticking to the screen.
As for drying, depending on the emulsion it varies but I've had best results with letting in dry for 6 hours with no fan. Fans have a lovely little tendancy to form pinholes in your screen.
I can dry a screen in about 10 mins by putting it under the flash dryer.
I dont know if I would suggesat doing that. I would think the that amound of direct heat would hurt the mesh. You can also sit the screen in the sun which wilkl dry quicker than that (as long as its sunny outside) Just dont do it when its windy as dust & dirt will get all over the mesh.
After burning we dry all our screens this way. Conserves energy at least a tiny bit.

Wouldn't exposing light-sensitive emulsion to the sun to dry defeat the purpose of even coating the screen?
Smeared Screen?
