"He who marches out of step hears another drum." ~ Ken Kesey
I'm a noob .Screen printing aluminum signs with nazdar 9700 inks and catalyst and I'm having a terrible time. Lots of globbing and I'm really not sure what I'm doing wrong. I've done a couple of jobs where everything turns out great and the next job , ink has spread under the screen. I made a vacuum table and my off contact is somewhere around 1/8". As far as my print stroke, I'm pulling printing and push flooding. I suspect that I may be pushing down too hard but sometimes when I try and do a lighter pull, I don't have enough ink coverage.
Try S-mesh it will make a big difference when print by hand. Also make sure your doing a hard flood. You could raise your offcontact where the blurred print is happening in the front.

If it works, the OP ought to know.@ Doug, I agree the 59000 series might be a better choice than 9700. But I knew a guy that printed EVERYTHING with 9700 and their catalyst for decades. (His shop always smelled like 9700, even in the office.) (He has now gone all UV and is quite happy.) Do you think the 9700 would actually "creep" more than 59000? Also 59000 offers easier clean up, or at least I always liked it better. We only used 9700 for printing on PVC sheet goods, like Sintra. 59000 on all aluminum signage.
