We didn't have too much trouble printing shirts. Even using discharge ink and a heat gun. I read the books and the forums here on GP and everyone seemed to be indicating that posters were even easier. I guess anything is easy when you know what you're doing.
But we don't.
Freddy built a poster press from Andymac's plans. We didn't completely finish it since we couldn't seem to find the carriage bolts, but we will. Soon. It worked well and held the paper great. But the other equipment was not so good.
To start with...bad squeegee. We didn't notice until we had ruined about 150 sheets of paper, but the one we got had a big dip in one side of it. Note to self: Always check squeegees for straightness.
Even though I've been doing graphics for longer than I care to admit and really, really know better, I still managed to go insane and design a poster that was almost impossible to register. I still can't believe it. Note to self: Don't forget everything you know.
We had clamps that would loosen up and let the screen shift, even when tightened with pliers. We ruined even more paper.
We couldn't figure out what we were doing wrong here:
I called a friend and he said it might be too much off-contact. Or maybe the ink was too thick. I still don't know. But we tried fixing both and it helped. We had less trouble with the black ink.
I was glad I bought 250 sheets of paper (Cougar 100 lb) to try to get around 100 prints. We needed them. It took us 2 weekends of frustration to get about 80-90 posters done. Only about a 3rd of those are registered really well. I'm only selling the good ones, by the way. lol.
But we took them to the Misfits show and they were a hit with all. Jerry Only liked them a lot and signed a few for us.
But if anyone has any advice or helpful suggestions for us, it would be much appreciated. We can't wait to do the next one.
cheers for sharing - I swear a lot when printing about 30-40% of my screens, the others are a dream and a pleasure - but I can empathise wholeheartedly
see your penultimate shot there with the ink smearing over the text...
this happens to me from time to time - but much less often than it used to...
if I can, I put small detail like that at the top of the screen (so in your case, print the red screen up the other way, 180degrees) - not sure why, but along with varying squeegee angles and pressure, very light flooding etc, it seems to help.
That big reverse that close to the bottom edge is always going to be trouble.
Wants to be 230-250 mesh
Be really aware of your print angle and flood and amount of ink, and where the puddle is at the bottom of the stroke - if it gets back on the stencil image before you flood you are screwed. it only take one print sequence to screw it up and get the ink underneath.
If it happens (bleeding) print off on scrap without flooding.
You just have to keep printing. You will have better luck printing areas that aren't big reverses, at least starting.
but fuck it, you did it, what's next?
- I think there are some 'register' threads in the archives - controlling registration is a lot more than a set of clamps.
