Their website sucks, even calling them is a gamble but it's your better option.
They only sell it in powder form then you mix it with clear, you have to use a lot but it'll make your eyes burn.
I wish someone else would make a good water based ink. I used to love the Ink Dyzyne water based till fucking Nazdar bought'em out and discontinued it. Union had one...discontinued. Why spend a bunch of money on water based when you can make your employees huff chemicals?
apparently the paint department at Home Depot stocks a brand of WB...
Yeah, there were a bunch of WB inks in the late 80s from all the major ink mfg., but the problem is non of it works very well on plastics, and plastics are the main material screen inks get printed on. Everybody has gone to UV because of ease of handling, but even it has limits. A bit expensive to get into for a small shop.
So no big market, no makee inkee for it. give TW credit, they pioneered it and they have stuck with it.
Does Sericol or Colormix make any in the states? We used to sell Coates Weiderhold (pre-colormix) and they had a nice WB, similar to the ink Dezyne Hydroplus.
