SEQUENTIAL DISPLAY MOSAIC FABRICATION FIXTURE AND METHOD OF MAKING MOSAICS

摘要

An exposure system for creating a single frame transparency or mosaic having an enlarger rack with a transparency fixture (50) including a light obscuring exposure mask (22) and a multi-axial table (100) for relative movement therebetween during an exposure process which results in a single transparency having four independent images, each of the images having spaced apart groups of pixels interlaced with the group of pixels from each of the other images, each of the images being selectable for projection by a movable grid mask. A method for preparing multiple images from a single transparency is also disclosed. The transparency is formed by sequentially exposing portions of a sheet film (240) overlaid by a gridlike mask (200), and correspondingly repositioning the film after each exposure such that a new interlaced area of film is exposed.
