This document applies to
—     critical evaluation of and comparison between transparencies, backlighted signs, reflection photographic or photomechanical prints and/or a reference object or image,
—     appraisal of the tone reproduction and colourfulness of prints and transparencies at illumination levels similar to those for practical use, including routine inspection, and
—     critical appraisal of transparencies which are viewed by projection, for comparison with prints, objects, or other reproductions.
This document is not applicable to soft-proofing displays, for paper manufacture, and other applications outside of graphic technology and photography.
