Abstract

L'invention concerne un système de solution d'encrier pour presse à imprimer, capable de filtrer, de régler la température et de réduire au minimum le moussage de solutions d'encrier. Le système de solution d'encrier permet de filtrer (620, 630) la plupart des particules contaminantes de la solution d'encrier. Le système de solution d'encrier peut contenir un ou des échangeurs thermiques (580) pour régler la température de la solution d'encrier. De plus, le moussage de la solution d'encrier est limité par des dispositifs de démoussage et un système de réservoir double.
