[X-Men:DOFP] What could Trask have learned from Ink?

Ink isn't a mutant. All of his powers come from tattoos given to him by a mutant. If those tattoos should fade, or the mutant who gave them to him wakes up, it's very likely he'd return to being a regular human.

With that being said, what could have Trask learned from experimenting on him? Or would the ink from the tattoos be more useful?

Ink in x-men days of future past isn't stated he is anything similar to the ink introduced in 616 so it can be deduced that in this universe he is a mutant, one that which probably gets power from tattoos similar to the other one but not because his tattoo artist is a mutant.
