Viewing conditions -- Graphic technology and photography

This International Standard specifies viewing conditions for images on both reflective and transmissive media, such as prints (both photographic and photomechanical) and transparencies, as well as images displayed in isolation on colour monitors. Specifically, it shall be used for:

  • critical comparison between transparencies, reflection photographic or photomechanical prints and/or other objects or images,
  • appraisal of the tone reproduction and colourfulness of prints and transparencies at illumination levels similar to those for practical use, including routine inspection,
  • critical appraisal of transparencies which are viewed by projection, for comparison with prints, objects, or other reproductions, and
  • appraisal of images on colour monitors which are not viewed in comparison to any form of hardcopy.

This International Standard is not applicable to unprinted papers.
