Best waterproof pen for matte/satin/gloss prints? Best thickness?

[chadpowell]

Hi guys,

I've just received several large prints that I will be signing, I'd like to find a suitable black pen that won't rub off a satin/gloss surface. Any ideas? Also what is the best thickness? A friend uses a 0.5mm but it seems a little too thin.

Thanks in advance,
Chad

Sakura 0.7 mm pigment pens are v good for this

If you sign on lab C-type prints, any silver / gold pen will do. Don't worry about buying waterproof - the photos are not! Inkjet pigment based prints are far more resistant and could be worthy a better pen.

Sharpie do a silver felt tip which has a reasonably fine tip
