reimerron, The art judges do have a point. Any print will hold more value if the print itself is signed rather than the matt or overmat. In addition - some collecters also like to see the print dated and feel that also can have an effect on the prints ultimate value. There are archival inks as well as pens for that matter that can be used for signing the front and as has been mentioned, pencil is the standard if signing on the back (on verso). Check out any photo auction site and see how the value of even well know work changes depending upon if the print itself is signed or not. This does not mean that you can not still sign the overmat as was suggested. I should also mention that "bleeding" a print to the edge of the paper is generaly not an excepted gallery standard. Its best toleave 1/2 to 1 inch white boarder around your image area.
