I didn't think an ink would withstand the the temperature (thinking
along the lines of markings either being etchings or printed then
encapsulated) but I have found an ink that could withstand the temperature,
can even be used on ceramic materials, only problem is it has the be air
brush stenciled, manufacture states it's not suitable for stamp or roller
application.
Okay so I've got no idea why such an ink isn't used to directly print to
the capacitor,
