All prints for show or otherwise put on sale are mounted, over-matted and framed with the cheap Nielson black anodized aluminum frames. I trim the prints after attaching the mounting adhesive in order to achieve a "perfect" mount with no adhesive showing. I need this because the over-mats are cut to reveal about 1/2 inch of the mat board. I have done some commissioned work with the bottom relief 3/4 inch to allow for a title, date and signature. I perform the mounting but I have the mats professionally made. In my opinion, glazing is essential for any work for sale or display, however I have entered competitions where frames and glass were disallowed.
