At first I shared your hesitation to sign the print, and I messed up a few for being a silly goose about it. I got over it. After about 200 prints.
But, you HAVE to manually sign each print, just inkjetting your name etc is pure tackola. It will scare collectors away for sure.
Personally, I think imposing a white border around the print just for you signature etc is over-the-top, hyper-retentive BS. I just sign the damned print, people love it. Just say NO to stupid prissy white borders. Use Micron 03 or 05 marker for RC and light colored areas on canvas, medium soft pencil for all others. Sometimes I do inkjet my last name at lower right in small type in a color closely related to what's underneath , but then I also sign my illegible authentic signature nearby. Put the name and sequence number on the back.
