Hey John! Albany tattoo shop owner here. Two questions.
Are you looking at the difference between the EU certified inks and US brands that choose not to certify, or feature different product lines for the continents? Ex. Dynamic
Second, do you have thoughts or a goal on how your research can be used to improve industry or product standards?

We haven't differentiated really between EU and US inks. Most of what we've looked at are what is available in the US and the same product seems to be available overseas. In chatting with ink manufacturers, my sense is that they don't really have alternatives to many of the banned pigments (e.g., blues and greens) and will likely just pull those inks from the market.
In terms of industry, a major project we are working on right now is just understanding what's in the ink bottle versus whats on the label (if it is labeled). We are finding a pretty high number of discrepancies, some of which are probably minor (e.g., using ethyl alcohol instead of the listed isopropyl alcohol) but in other cases we are finding different pigments in the bottles or one additive swapped for another. As a starting point, a complete and accurate listing of ink ingredients seems like an important first step. -JRS

Thank you for the reply! In your follow up to one person about people not understanding the common pigments, we go through that a fair amount. Something like “I’ve had a reaction to blue ink do you use a different brand that wouldn’t give me a problem”. Or carbon black pigment being carbon black everywhere.

No buy any China "certified" ink that for sure.
