Abstract
Abstract Process and apparatus for printing a plurality of imposed pages in which proofs of said pages are manufactured, the proofs then being confined in co-planar, predetermined relation by engaging the sheets solely along selected edges thereof, and while holding the sheets thus confined manufacturing a printing plate or other reproductions therefrom. In one embodiment the proofs are on opaque or light impermeable sheets, while in a second embodiment they are on light permeable sheets. In the case of the opaque proofs used to make a printing plate, the plate is produced from a photo negative of the proof, whereas if the proofs are on light permeable material a plate may be produced directly by passing light through said proofs onto the sensitized surface of the plate material.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
103 words
The process of printing a plurality of imposed pages comprising: a. manufacturing proofs of each page on sheets of material on which the matter to be printed is positioned in predetermined areas thereof, b. confining said proof sheets in a co-planar and predetermined relation to each other by engaging the sheets solely along selected ones of the sheet thickness edges thereof, whereby the entire upper surfaces of said sheets are unobstructed, and c. simultaneously reproducing on a single surface the subject matter of all of said proof sheets while maintaining them confined and related to each other as set forth in (b) above.
Claim 2
Dependent Claim
103 words
The process of printing a plurality of imposed pages comprising: a. manufacturing proofs of each page on sheets of material on which the matter to be printed is positioned in predetermined areas thereof, b. confining said proof sheets in a co-planar and predetermined relation to each other by engaging the sheets solely along selected ones of the sheet thickness edges thereof, whereby the entire upper surfaces of said sheets are unobstructed, and c. simultaneously reproducing on a single surface the subject matter of all of said proof sheets while maintaining them confined and related to each other as set forth in (b) above.
Claim 3
Dependent Claim
98 words
The process of claim 1 in which said proofs of each of said pages are printed on sheets of light permeable material, which sheets are confined in said co-planar and predetermined relation to each other as set forth in (b) of claim 1, above, and utilizing said confined sheets to manufacture directly therefrom a printing plate by superimposing said sheets relative to the treated surface of a plate and exposing the same to light, thus preparing the plate for subsequent chemical treatment to produce a printing plate which may be used to reproduce the matter on said sheets.
Claim 4
Dependent Claim
33 words
The process of claim 1 including the further step of producing a photographic film of the entire array of said sheets while so confined, and utilizing said film to produce a printing plate.
Claim 5
Dependent Claim
45 words
The process of claim 1 in which the said proofs are manufactured on sheets of opaque material, and including the further step of producing photographic film of the entire array of said sheets while so confined, and utilizing said film to produce a printing plate.
