Abstract

Dispositif pour la détermination de la répartition de la densité sur la maquette d'une forme d'une machine à imprimer. Par zone 8 est prévu un certain nombre de cellules d'exploration 9 placées à une distance déterminée les unes des autres et de la maquette 4, ces cellules 9 étant insolées simultanément et raccordées chacune par un dispositif de réglage 10 à un amplificateur totalisateur 11 à la sortie duquel une valeur proportionnelle à la répartition de la densité est disponible.Device for determining the density distribution on the model of a form of a printing machine. Per zone 8 is provided a number of exploration cells 9 placed at a determined distance from each other and from the model 4, these cells 9 being exposed simultaneously and each connected by an adjustment device 10 to a totalizing amplifier 11 to the output of which a value proportional to the density distribution is available.
