screen printing > Newbie
printed my first job on the auto- came out horrible
BBB:
I think that your right. Flashing that much got those pallets pretty hot. I'm doin fine, (not worrying about a job due tomorrow)lol. You'll get it right, just start out on something easier, and dont try black with no UB. Angle of squegee varies job and screen to job and screen. Thats why its adjustable. Like I said, use your manual experience to guide you. I rember trying more upright, the better. Just watch the flood bar doesnt push thru the screen...Nothing to do about this job, but at least watch it the first few shirts, and if you have problems, fix them or go to manual, before 150 are done...will write you on email. Nice to hear from you
Printhouse:
I would love to see a manual to auto thread! I have been so busy I have not even been able to move my javlin into place yet. Hopefully I will have some downtime this week to start setting things up.

Screen printing ink is designed to stay put - this is why you can turn a bucket upside down, and the ink won't pour. Slow shearing force doesn't help the ink spread across the shirt to produce a uniform deposit.
Many drug induced printers, grasp for a chemical additive that reduces viscosity - BUT that defeats what the ink designer was aiming at because the ink will penetrate the shirt and you won't get a film or coating.
Fast blade speed, low off-contact, high mesh tension and a blade that stands up to the resistant forces (thick ink and mesh tension).

Thanks... I'll be trying a faster blade speed. I've been guilty of reducing ink and also of double stroking to get the mesh cleared.

Give me a call Shane.... (580-748-0601) No need to reinvent the wheel. We've all been there and I made a few calls myself along the way.
