Definitions

  • This invention relates to a process of digitising Sapp and Rackwell encoded films plus other suitable film systems which may be capable of a similar application.
  • Sapp and Rackwell encoded films were primarily designed in the early 1980' s and late 80' s to be production systems within the publication production procedure. More recently, the production systems that are used have changed to digital systems, and the older Sapp and Rackwell encoded films are no longer used. In fact, no Sapp systems and very few Rockwell systems are capable of further production. Due to the very singular use of these systems it became apparent that transferring the stored data to a digital format was not something that was a natural development step, so companies have been left with an unusable back catalogue.
  • a further object of this invention is to provide practical and usable methodology for digitising film systems .
  • Another object of this invention is to provide a cost effective method for digitising film systems.
  • a yet further object of this invention is to provide a method for digitising film systems which maintains image resolution.
  • Another object of this invention is to provide a method of controlling of image positioning.
  • a still further object of this invention is to provide a method for digitising film systems which allows image enhancement when required.
  • a final object of this invention is to provide control of encoded Sapp and Rackwell film for imposition purposes.
  • a method of converting Sapp and Rackwell films into a digitised format comprising the steps of scanning the hard copy image, identifying the encoded image on the file and creating a digitised record of the said image.
  • a basic stream fed scanner is used to scan the hard copy image.
  • the scanning resolution may be 200, 300 or 400 dpi.
  • a drive mechanism is used to accommodate the various types of gauges which enabled the Sapp and Rackwell films to flight through the scanner head.
  • the drive mechanism comprises specially constructed spindles.
  • the loading of encoded films is via a sprocket driven loader which allows the flow of work to be constant and controlled.
  • the film may be l ⁇ mm or 35mm roll film.
  • a further option is that the film may be l ⁇ mm cartridges.
  • linear edge technology is used to enable Sapp and Rockwell systems to be controlled in one direction.
  • a template overlay is added to the hardware being used to provide control of the images in all directions.
  • the process has a speed of 200+ images converted to digital format per hour.
  • a final file format is used which lends itself to the consistency and quality required of the system.
  • any number of images may be digitised and file formatted in 1 complete segment.
  • newly created digital files are routed to a printer and the image resolution status is checked.
  • the digitised files are stored on CD-ROM or on the Internet.
  • the electronic transfer method of the present invention provides an online process for digitising back catalogues of Sapp and Rackwell files.
  • a Sapp or Rackwell encoded film is scanned using a basic stream fed scanner with a resolution of 400 dpi.
  • the film is fed through the scanner using a drive mechanism comprising specially constructed spindles, and the film is loaded via a sprocket driven loader.
  • the feeding of the film allows the flow of work to be constant and controlled.
  • Both the vertical and horizontal positioning of the film is controlled.
  • the positioning is controlled using both linear edge technology and a template overlay which is added to the hardware which is being used.
  • the combination of the two technologies provides control in all directions of the images being digitised.
  • a final file format is used which allows the digitised images to be viewed on a computer.
  • the format that is used provides both consistency and quality.
  • the newly created digital file is then routed to a printer and the resolution of the image is checked.
  • the digital files can then be placed in a database or provided in an online format for viewing over a computer network such as the Internet.

Abstract

L'invention concerne un procédé de numérisation de film du type « Sapp and Rackwell » codé. Le procédé comporte les étapes consistant à scanner l'image sur papier, à identifier l'image codée et à produire un enregistrement numérisé de cette image. L'avantage de ce procédé est de permettre la conversion de films du type « Sapp and Rackwell », auparavant inutilisables, en un format numérique utilisable.
