ABSTRACT:
An improved approach to printshop paste-up operations involves a vacuum table having a grid of closely spaced air passage apertures in the top surface, a mounting member for receiving sheets carrying text and illustrative material comprising a sheet apertured to match the grid of said top surface having an imperforated border facilitating vacuum positioning on said top surfaces with apertures aligned, arranging and rearranging sheets of text and illustrative material on said mounting member while preventing unintended movement thereof by the vacuum effect at apertures covered thereby until desired composition is achieved, and then bonding a transparent plastic sheet over the mounting member and arranged sheets of text and illustrative material to provide an assemblage which is durable for transport, printshop use and extended storage. The expendable mounting members are provided in a number of standard sizes, and the vacuum table includes adjustable baffle means to confine effective vacuum to the size mounting member in use. In a preferred adaptation the vacuum table is superimposed on a light source and both the top surface and the mounting member are translucent, facilitating a combination of back lighting and incident lighting during such paste-up operations.
