Inkjet system, method of making this system, and use of said system

摘要

An inkjet system including a printhead with an ink-fillable chamber operatively connected to a piezoelectric actuator and provided with a nozzle for the ejection of ink drops in response to the energization of the actuator, which actuator is connected to a measuring circuit for measuring an electrical signal generated by the actuator in response to the deformation thereof, wherein the system is configured such that a natural frequency of said system corresponds substantially to a natural frequency of a disturbance in the system.
