The EleJetTM print technology is an example of a direct electrostatic printing (DEP) process specially adapted for industrial digital printing applications.The key characteristics include a source of charged toner particles with narrow charge to mass distribution and well behaved fluidity, a global back electrode that attracts the charged toner particles from the toner source to the paper or intermediate receiver, and a particle modulator (printhead) in between the toner source and the (intermediate) back electrode. The modulator is made of a plastic body with passing holes surrounded by control electrodes.In this electrostatic process the distance between the toner source, toner modulator, and (intermediate) image receiver is kept constant by dynamic adjustment. Pulse width modulation is used in combination with rather low addressability to achieve high image quality.The combination of sufficient printing speeds with dynamic distance control and good toner design makes EleJetTM printing an excellent technique for Industrial Wide Format applications.
