hello, we are just starting out and trying to get our first screen ready. we have done everything according to instructions but when we let the emulsion dry overnight and come back the next day there are bubbles all over the bottom (non t-shirt side) of the frame. this has happened 2 days in a row now. we cleaned, degreased, etc. all according to the instructions, using yellow bug lights and all that. can anyone help??? i have attached a pic of the frame. thanx!
p.s.: the photo just shows the front (image side) of the screen.
Ok well, I can almost guarantee that its because too much emulsion is going on the screen.
If you lay the coat too thick, it begins to goop up, and drip like water does from a ceiling.
Try this, when coating the screen with you scoop coater, coat once, then go over again, and give it a little more pressure. this usually cleans up any left over emulsion.
Key point, is that you want a think even coat of emulsion. Thick doesn't pay off! {Unless your doing High Density, but I don think that is what your faster!}
Good luck!
I use a heater to make my screens dry quicker too!
City water or hard water can cause similar bubbles. When this happened to me, i saw it 5 minutes after coating and no matter how thin the ink, the contamination was causing the problem.
I always degrees, scrub, thoroughly rinse and use compressed air to remove the rinse water out of the screen. Not everyone has compressed air and similar results can use a shop vac or just shaking the screen in the air.
