The front side of a picture frame moulding when viewing the frame's profile directly head on.
Profile Face refers to the front-facing surface of a picture frame moulding when the frame's profile is viewed directly head-on. It is the visible plane of the moulding that is most directly seen by the viewer once the frame is mounted on the wall. The profile face is critical to both the aesthetic presentation of a frame and its functional integration with the artwork it surrounds.
