For the long-term archiving of digital images, a laser film recorder is being developed. It images color microphotographs on unperforated 35mm silver-dye bleach material in high resolution (pixel-size 3 micrometers).

The goal of the archiving process is to achieve a precise colorimetric reproduction. However, color gamut and dynamic range of the photo-material used is relatively small. Consequently, an “archival colorimetric transform” has been developed. Its purpose is to record a maximum of the original's information on the microfilm, using adequate gamut compression based on sensitometric measurements of the photographic material.

A modified IT8 scanner target is also recorded on the microfilm as a reference for the reconstruction of the archived color information.

More about this publication?
  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
