Operation
On each print station, an ink circulating pump delivers ink from the tank to the print station. As the printing progresses, temperature of the ink varies over time. This variation in ink temperature results in higher solvent evaporation, which in turn means higher top-up solvent consumption. The ink flows through the inner spiral tube of heat exchanger to the print tray. The chilled water flows in the outer side of the tube and inside the shell, thereby cooling the ink. This ensures that ink temperature is maintained constant at set value.
