The reason I`m asking is because my boss, which coincidently is as well my wife, wants us to use waterbased inks for printing onto dry fit tees.
Matsui pointed us now towards their EN-base/white. It`s their acrylic ink which apparently works very well on dark poly tops, especially if you add a small percentage of Fixer F. According to Matsui the EN base/white cures already at a lower temperature then their standard waterbased whites and with the Fixer F it can be cure at real low temperatures. How low, well I will try it out and report back.
