Abstract:
1. A system for setting up a printing station, the printing station comprising at least one adjacent pair of printing rollers, said at least one adjacent pair of printing rollers including at least one ink transferring roller and an impression roller, the system comprising: a camera for detecting the partial presence or absence of a representative impression printed on a print material, said representative impression being printed on said print material by transferring a print liquid from an ink tank to said print material, through said printing rollers; an actuator interface, coupled with at least one actuator, for directing said at least one actuator to move at least one printing roller of said printing station, to change the distance between rotation axes of said at least one adjacent pair of said printing rollers; and a processor coupled with said camera and with said actuator interface, for at least one of said adjacent pair of said printing rollers, said processor receiving an output from said camera, said processor determining a no-print threshold distance according to said output from said camera said no-print threshold distance being a minimal distance between said rotation axes of said at least one adjacent pair of said printing rollers, at which no print liquid is transferred to said print material, which is a minimum distance increment which the actuator can controllably adjust from a maximum distance between said rotation axes of said adjacent pair of printing rollers at which a partial presence of said representative impression is generated, said processor directing said actuator via said actuator interface to set the distance between said at least one adjacent pair of said printing rollers to a respective working distance, the respective working distance being at a predetermined displacement from said no-print threshold.
