Abstract
An ink circuit particularly intended for pressurizing a pigment ink, for an ink jet printer, is disclosed. The main pressurization line (40) is connected to a first head (9) of a compressor (7), and the depressurization line (45) is connected to a second head (15) of the same compressor (7). Both pressurization and depressurization lines are totally independent from the ink circuits. Magnetic agitators means (3, 4) are provided at the base of the reservoirs (1 and 2) in order to avoid pigment settling. The ink circuit applies to the marking of media or supports, requiring an opaque white ink.
