Claim 0:
1. A system for regulating ink supply to injectors of a print head with ink recirculation system, characterised in that the system for regulating ink supply comprises at least one measurement assembly installed parallel to the flow of ink to the injection head emulating the conditions of said injection head, where the measurement assembly of the system for regulating ink supply comprises at least:
a pressure measurement point to which a pressure sensor is connected;
a first connection of the pressure measurement point in an ink supply inlet circuit of the print head; and
a second connection of the pressure measurement point in an ink supply outlet circuit of the print head;
where the first and second connections of the measurement point to each of parts of an ink supply circuit have identical characteristics of hydraulic resistance to ink flow; and
where each connection of the measurement point to each of the parts of the ink supply circuit includes at least one or more conduct segments and connection elements to the ink supply circuit, where the hydraulic resistance to ink flow from the point of connection of the measurement assembly at the ink inlet circuit of the print head to the pressure measurement point is identical to the hydraulic resistance to ink flow from the pressure measurement point to the connection point of the measurement assembly at the supply outlet circuit of the print head.
