An apparatus for capturing and recording the content, ownership, and/or bibliographic source of documents reproduced on a reprographic device, and more particularly for tracking the reproduction of specified information, especially copyrighted documents, is connected, preferably detachably, to any of various reprographic devices. The apparatus includes a digitizer for digitizing desired pages (such as those containing title and author information) output from a main portion of the reprographic device, a recording device and medium for storing said digitized pages, a counter for counting the number of reproductions made and optionally inferring the number of originals, a controller for controlling the operation of the apparatus and, optionally, a control panel for interacting with the operator of the reprographic device. When reproducing copyrighted information, an operator makes a reproduction of the pages containing title and author information, digitized images of these pages being stored on the recording medium. The counter counts the total number of copyrighted and other reproductions made, the counted number of reproductions also being recorded on the recording medium. The recording medium is then used to determine the number and nature of copyrighted reproductions made by the reprographic device. The device may also be used for other applications where reproduction of particular types of documents is restricted, or for storing document contents as part of an information storage and retrieval system.

Tracking the reproduction of documents on a reprographic device

Disclosed is a printing plate precursor which comprises a base layer, a layer of photohardenable material, and a layer of softenable material containing photosensitive migration marking material. Alternatively, the precursor can comprise a base layer and a layer of softenable photohardenable material containing photosensitive migration marking material. Also disclosed are processes for preparing printing plates from the disclosed precursors.

Camera speed printing plate with in situ mask

A process for depositing particles within a softenable layer to form a migration imaging member wherein the layer is softened by heating, exposed in a first deposition zone to a high impingement rate of vapors of selenium or selenium alloy moving along in a line of sight path from a selenium or selenium alloy source to form a sub-surface monolayer of spherical particles comprising the selenium or selenium alloy, removed from the first deposition zone prior to a substantial dropoff in transmission optical density, exposed to a lower impingement rate of vapors of selenium or selenium alloy in a second deposition zone to increase the size of the spherical particles while maintaining a narrow particle size distribution and achieving a high surface packing density thereby increasing the transmission optical density of the imaging member, and thereafter removed from the second deposition zone prior to a substantial dropoff in transmission optical density.

Multistage deposition process

A camera, processor and viewer is disclosed wherein the migration imaging system is utilized as the photosensitive element. The device is provided with the capability of recording an original image on the migration image film, instantly developing the image by means of heat application and also provides means for viewing the developed image immediately upon development without removal of the migration image film from the device. The device is semi-automatic in operation and is electrically powered alternatively by batteries located within the device or supplied with electrical current from an external source by means of a detachable cord.
