Hey there people. So I've only recently started printing posters (t-shirts for a few years), and have had a few bumps so far. I'm sure there will be many more to come, but here are a few questions I'm still unclear about. So far I've built a 4x4' vacuum table (everything's bigger in TX?) w/a foot pedal, using 230 mesh 30x40 screens (manually), using Speedball Acrylic inks..
1. Can too much off contact cause a print to bleed out? I had a tiny 2 letter print to do, and had a hell of a time getting it to come out clear. Black ink, 3" normal durometer (70?) squeegee. I noticed if I flooded the image too hard after the print, it was a definite mess the next time around. But it was just super inconsistent. One pull would be fine, the next, a blobby mess. Put masking tape on the print side and peeled off a couple times between prints to get the excess off, then tried again. Finally wound up removing the quarters I was using for extra off contact and this seemed to help, a little. Any ideas? I had put them there because my 1st print had too little off contact, and the paper kept sticking to the screen after my pull..
2. Registration. Using DYMO Embossing tape to create an upper left "L" and a lower left "L" for registration. It seems to be fairly accurate, but not as exact as when I use my t-shirt press, obviously. I'm a perfectionist, so it's really hard to just accept 'ballpark' registration. I know some artwork does not need to be perfect, but then I see some Flatstock shit that makes my brain crawl. Looks like perfect damn registration. I want to eventually offer damn good prints to my customers, w/very little inconsistencies. Do I need to just suck it up and keep practicing, or is this something I just need to get used to? Or is there something I'm missing? Is there any tape that's thicker than this DYMO one?
3. Registration between colors. Right now, I print one poster w/the 1st color, then do the whole run of that color. Then I re-position the original poster in my "L's", bring the 2nd screen over, eyeball the registration over that print, then clamp it down into place. Is that the normal way to register between colors?
Those are the biggies for now. I really appreciate any tips or feedback..
