Print signing question

I've Googled myself into confusion on this matter, so I figured I'd ask the experts. I'm going to plaq mount some prints, so no borders, and I'm wondering the best way to sign them. Right on the front, I'd guess. What type of pen/marker would I use for luster paper? Do you folks use a full signature or just initials. or ..? I'd appreciate any advice you can offer.
Thanks,
Paul

I use a fine tipped sharpie for my lustre prints...works fine. You can use silver or black depending on the print. I use full signature but that's just a preference. Sometimes I think initials would be less obtrusive. Also, I always practice my signature on a small piece of paper until I feel I have it the way I want it before signing the actual print.

Sorry I missed you at Flatirons last Saturday. I didn't decide to go there until about 10:00 p.m. on Friday night. I've got to stay in touch better. Did you get any shots you can post?
And, I wish someone would order a print so I can have to make the decision you are having to make.

I also use a fine point sharpie, you can get them in a variety of colors but I most always use black. I use my initials and last name, i.e. D.J. Gerth. I also date it. On matte paper I use a pilot precise V5 RT (very fine point).

I usually use a fine-point acid-free silver-metallic pen, cause it shows up on almost any photo and looks kinda cool to boot. You can find them at Michaels or online. They're not usually as fine point as black pens, so you can also use black if you have a light part of the print you can sign on.

I'm with Grant on the acid-free pens. I use black, silver, and gold pens depending on the colors in the image. I have multiple sizes for each, depending on the size of the image/signature. The various pens can be purchased at Hobby Lobby, Michael's, Meininger, and, of course, Amazon.

I've been wondering about this same thing for some time, so it is helpful to hear what others do. Thanks for posing the question and providing responses!

You should not be using a Sharpie! They are not acid free and the black can fade to an off brown plus affect the image. Use acid free pens. I use these:

Though I am not sure that the last is acid free! I only use that for signing on dark prints. To be honest I digitally sign stuff and use "actions" in PS for standard sizing with signatures.

I signed my name over and over until it was perfect. Took a picture of it with my macro lens, processed it in PhotoShop. During the processing I removed the background and then created a black and silver copy. I then added it as a signature in LR3. It works great 99% of the time. The image was big enough that i just tell LightRoom that i want my signature to be scaled at 3%. This gives me a nice clean signature with no pixelation. 3% seems to make it about the right size for everything I have printed.

It is not quite as nice as a real signature though.

Great tips everyone. Thanks!
