The invention relates to a circuit for supplying liquids with different characteristics for a multinozzle spray head. This supply circuit comprises four separate main devices: - two identical supply devices (37 and 38), each managing a liquid with defined characteristics for supplying the spray head (46); - a device (39) for distributing and recovering the liquid supplying the spray head (46), which device is connected to the outlet of the supply devices (37 and 38); - a device (40) intended to manage, on the one hand, the quality of the liquids by monitoring their viscosity and their pressure, and, on the other hand, the rinsing of the other three devices (37, 38 and 39). The invention applies to ink-jet printers. <IMAGE>
