Title: Body heat active screen print inks
Post by: 3Deep on June 01, 2021, 04:34:08 PM

Customer looking for body heat active shirt's, but I told them it's not the shirt it's the ink on the shirt that reacts to body heat, so anyone know where to find this inks? use them Pro/Cons...I heard about them years ago but never really looked into it, when I was looking for the light activated color inks.  Just found out it's sweat activated

Hey D!

search for thermochromic inks. We used it one time and the body temperature needed to produce the change was pretty high. Magna might be better though.

So far it looks like it needs to get wet from sweat, thanks for all the info
