The ink pH is measured by a dedicated sensor, which sends the measurement with electronic control, which operates with a reference set by the operator of the base liquid valve and the water valve.
The system of control and correction of the ink pH G31, is composed of detector pH specially developed, one per color, pneumatic valves and management software.
A pH probe, which can be integrated in the detector viscosity, measure the ink pH. The G31 automatic system, according to the pH value determined previously by the operator during the calibration, regulates the flow of the base liquid and water, so as to maintain a pH stable ink during the printing process.
