Abstract

a. L'invention concerne une installation de commande pour optimiser le rapport entre l'humidité et l'encre dans un duplicateur lithographique comportant un cylindre porteur d'original. b. Cette installation est caractérisée en ce qu'elle comporte des moyens de commande agissant par signaux sur le débit d'humidité, des moyens d'amenée de l'humidité au cylindre, ainsi que des moyens de contrôle, des moyens d'amenée d'encre au cylindre, les moyens de commande recevant des signaux d'entrée en fonction d'au moins une condition physique liée à l'historique des états de travail et de repos de l'encre. c. L'invention est applicable aux duplicateurs lithographiques.at. The invention relates to a control installation for optimizing the ratio between humidity and ink in a lithographic duplicator comprising an original bearing cylinder. b. This installation is characterized in that it comprises control means acting by signals on the humidity flow, means for supplying humidity to the cylinder, as well as control means, supply means for ink cylinder, the control means receiving input signals as a function of at least one physical condition related to the history of the ink working and idle states. vs. The invention is applicable to lithographic duplicators.
