In a doctor-blade system consisting of a strip of flexible material supported by a blade-holder fitted with resilient means for applying the free marginal portion of the doctor-blade against the screen during printing, at least one internal longitudinal passageway is formed within the blade-holder body and communicates at intervals with the internal blade face and with the resilient means, any trace of ink which may have infiltrated into the system being discharged to the exterior by means of an external supply of fluid under pressure.
