I'm looking at producing some larger fine art pieces printed on metal (there are a few pro vendors which do this). If I wanted to sign these pieces (on the front, in the corner), does anyone know of a type of pen that could be used which won't damage the art and will hold up over time?

A metal print? A Graver! Seriously, once reading @rfusca's comment to @cabbey's answer, I am not sure that these fit, but I have Sharpie Industrial Super Permanent Ink pens, that's supposedly non-erasable/unwashable under extreme chemicals and environmental conditions. UPDATE: According to @rfusca, this specific type is acidic and should not be used to sign a print. |
