"He who marches out of step hears another drum." ~ Ken Kesey
In reading this and other forums, I hear people refer to "HSA" WB inks, which I understand to mean "High Solids Acrylic" inks. I also hear mention of "Traditional" WB inks, or "Non-HSA" inks. But I cannot find any references to specific inks which are "non-HSA". Can anyone provide specific examples of "Non-HSA" inks? It seems like maybe there is a range of inks. For example, I asked a vendor about the Permaset Aqua inks, and I was told these inks are "semi-opaque". What would be an example of a "completely transparent" ink? How is the chemistry different in these inks? Are we talking about the difference between chemical dyes and (acrylic) pigments? TIAChris

TIAChrisYou are correct, that HSA is high solid acrylic ink. Traditional waterbased ink, and discharge ink are low solids ink. They aren't as opaque. The difference is the amount of solids inside the ink chems.i have a pretty cool vid. from a magna seminar i can send you, if you want to dm me.
Yes, amount of solids. But the notable difference here is how each ink is intended to work. Traditional or regular WB inks wick into the fabric. HSA inks are coatings and need to be built up to a film thickness that works for the application, just like plastisol. I don't see too many traditional/regular WB ink prints these days so it might be confusing without a physical reference. Think of a print that, like discharge, cannot "crack" when you think of traditional WB. Think of a coating, a printed film on the fabric, when you think of HSA. When sourcing product, clarify if it is intended to print on or in the fabric.
Not trying to hijack the post here, but this seems like a good place to ask this questions. Are HSA inks meant for printing on fabric blends? For my shop, I use regular water base for light garments and discharge for darks. The only time I will use HSA is when printing on blends. Also, when underbasing your water based prints, do you usually prints HSA on top? Or will regular water based inks do the job since they're getting printed over an underbase?
Exactly what Eric just said. And on blends it is our go to. Throw in some warp drive and you can have a potential winner of a print.
