Abstract
Abstract An apparatus is disclosed for printing a border on a photographic print. The apparatus is particularly useful for printing black borders which have always been difficult and costly to produce. The apparatus includes a light source within an enclosure having a translucent flat top surface to emit light and a straight edge at one side thereof, the enclosure having sides formed from opaque material. A further flat surface is positioned in the same plane as the translucent surface extending from the straight edge, a platen is formed from opaque material extending over the translucent surface with a sealing and pressure strip over the straight edge, a right angle corner frame positioned on the translucent surface with one arm having an edge parallel to the straight edge, an adjustable guide means for the corner frame and a locking means for locating the corner frame in a position on a linear path.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
152 words
An apparatus for printing a border on a photographic print comprising: light source within an enclosure having a translucent flat top surface to emit light and a straight edge at one side thereof, the enclosure having sides formed from opaque material, further flat surface in the same plane as the translucent surface and extending from the straight edge, platen formed from opaque material extending over the translucent surface, preventing light emitting from the enclosure, the platen being removable and having a sealing and pressure strip extending along the straight edge, right angle corner frame having an edge of one arm parallel to the straight edge for aligning a photographic print, adjustable guide means for moving the corner frame in a linear path such that the edge of the one arm is always parallel to the straight edge, and locking means for locating the corner frame at any position on the linear path.
Claim 2
