Ink coming off in the was is uncured. When you try a new ink, you need to give it the stretch test at least when it comes off the belt. If it cracks, more heat please. Someone mentioned that this ink is reflective? Like parabolic reflective, or just because it's "metallic"? And, yes, the better the dryer, the better the cure. A lot of infra-red only dryers need to be checked even with just different colors of ink... crappy lesson, but effective, yes?
