@Roger2005 I found another way that might be useful! Instead of tattoo like transfers, something like vinyl could work.
Printable HTV (Heat Transfer Vinyl), you can print on these in your inkjet then cut them out of the template then use a iron or heat gun to apply to the MD.. I think the transfers come with heat protective film.
Im going to try this myself on a few MDs, just waiting on the sheets to arrive.
