Hi Guys
I have recently migrated away from my normal sphere of t-shirt decoration (vinyl, sublimation etc) into screen printing. The job is a basic white print going onto a red tshirt. I am using union plastisol ink py2k 1026 bright white. I am using a heat press to cure, as I have one, and was told that this would do. The problem I seem to be having is when I cure the t-shirt (170 degrees c for 15 secs ) I seem to have residue of ink on the silicon paper after pressing. Any ideas or suggestions would be great. Many thanks
i am also using a heat press for right now but i do mine at 325 degrees for about 5 seconds, try that and see if it works, the temperature on the ink has to reach 320 degrees in order to cure!
thanks Joe, I have tried this since, and with various different culminations of settings, but I have the same result. I have scoured previous listings, and I think it could be a pressure related problem. I am using a swing press with light pressure, but it seems that I will have to rig smething up so that the platen does not touch the t-shirt at all.
thanks guys for the info. I have since tried putting a stopper on the bed of my press, so that there is no contact at all with the ink when pressing. It seems to work just fine, but I am in the middle of doing a wash test just to make sure.
effective curing of plastisol inks?
