One possibility if you are not going to produce limited editions is to just date the print, possibly with a number for the N-th print produced on that date. That leaves your options open for later and uniquely identifies the print as it is sometimes important to future collectors *when* a print was made. There have been several discussions on where, and with what, to sign a print.
