Abstract

L'invention concerne un appareil destiné à analyser un organe portant une image, par exemple un film photographique portant une image à imprimer. Selon l'invention, la transmission lumineuse est mesurée dans différentes positions de colonnes du film correspondant à des colonnes à imprimer, ainsi que dans des zones parfaitement transparentes, parfaitement opaques et ne portant pas le film afin que les données de transmission lumineuse obtenues dans les différentes parties des colonnes puissent être corrigées, avant utilisation pour le réglage des clés d'encrage d'une presse d'impression. Application au réglage automatique des machines d'impression
