writing on the back of prints

Anybody have any advice or "dos or don'ts" for writing on the back of prints? Particular kinds of pens that bleed through or that don't bleed through?
Thanks

It might help to consider the use of labels?

Don't.

A lot photographers sign and date their work. Surely we have some here that do?

Soft pencil.

Many do including myself depending on the circumstances. I normally use a label on the back and I will put my signature in the image via Photoshop on the front if that is what I want. On very large prints I hand sign but use gold foil that you lay on the image and then sign over it which transfers your signature into the print. No ink is ever transferred to the image. The gold foil (which is also available in silver) can be bought at photo stores that service the professional market.

I wouldn't suggest ever using an ink on the image. I've seen people use the so-called permanent markers and let the ink dry real good. Once the images were stacked and got into a more humid climate some of it transferred. Labels or using photoshop is your best bet in my opinion.
