If you mean you want to do transfers for dark shirts...
Pigment ink and 3g or jet opaque 2 paper.
and the 7210 is fine.
People in the US like cobra inks pigment ink.
If you mean actual vinyl then you need to look into a veracamm or something like that which is designed for solvent or eco solvent inks.
A 7210 will not work with solvent inks, the ink will melt many parts as well as solvent inks need heaters to heat the vinyl to the correct temps.
