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.
