Abstract (en)
[origin: EP0422365A2] A control system for operating at least one set of nozzles (30) on a spray bar (26) and at least one set of plungers (408) on an ink injection device for a printing press. The control system has a memory for storing at least damp rate curve data and ink rate curve data which is utilized to control operation of the nozzles (30) and plungers (408), respectively. A processor is connected to the memory and provides a damp rate control signal as a function of the damp rate curve data and an ink rate control signal as a function of the ink rate curve data. A first interface for connecting the set of nozzles (30) to the processor is responsive to the damp rate control signal to control operation of the nozzles (30) and a second interface for connecting the set of plungers (408) to the processor is responsive to the ink rate control signal to control operation of the plungers (408). A communication bus system is connected to at least the memory and is operable in response to a received rate curve message to alter the damp rate curve data and the ink rate curve data stored in the memory.
