Track image registration system

Image registration apparatus for photosensitive media comprising;

• a) a resilient mat having an elongated aperture exposed through a media support surface of said mat;
• b) a track defining a slideway mounted within said aperture;
• and
• c) media registration means including a registration pin for mating with an aperture in media supported on said mat, wherein a base member is supported along said track and has a cavity and an open end thereto, which open end receives said registration pin, and wherein said aperture includes a region where the open end is exposed through the media support surface such that said registration pin may be inserted or removed from said track and through the media support surface without disturbing said mat.

Image registration apparatus comprising:

• a) means including a table and a transparent cover which mounts to said table for imaging photosensitive media exposed through said cover;
• b) means for creating a sealed cavity between said cover and table and wherein said cavity contains the media;
• c) vacuum means for evacuating air from said cavity;
• and
• d) media support means for supporting said media on said table and including 1) a resilient mat having an elongated aperture, which is exposed through a surface that supports the media, and a track mounted within said aperture, wherein said track includes a slideway and a registration pin mounted to the slideway to project above said mat and mate with the media and 2) inflatable means for inflating and engaging the media with the cover prior to engaging the vacuum means.
