SYSTEM FOR APPLYING A PRINTING LIQUID OR PRINTING ADJUVANT TO A GRAVURE ROLLER

摘要

The present invention relates to an application system for applying a printing liquid or a printing auxiliary liquid to a rotogravure roller, comprising: a vat (B) containing the printing liquid (L) or printing auxiliary liquid; a closed-chamber doctor blade device (D) communicating with the inside of the vat (B) by means of conduits (C1 - C5) forming a closed circuit, which is configured and arranged so as to extract the liquid (L) from the vat (B) through a first conduit (C1) and to apply same on the outer surface of the rotogravure roller (R), and to remove the leftover liquid and return same to the vat (B) through a second conduit (C2); and a viscosimeter (V) arranged inserted in the closed circuit and in fluid communication with the inside of the conduits (C1 - C5) for measuring the viscosity of the printing liquid or printing auxiliary liquid flowing therethrough.
