Abstract (en)
[origin: EP0712056A1] There is provided a device for direct electrostatic printing (DEP) on an intermediate substrate or on a final substrate, comprising a back electrode (105), a printhead structure (106) made from an insulating material comprising a control electrode in combination with printing apertures (107), a toner delivery means (101) presenting a cloud (104) of toner particles in the vicinity of said printing apertures (107), characterised in that said printhead structure (106) is thightly stretched over a frame by means of lateral forces applied to said printhead structure. The printhead structure (106) is thightly stretched over a frame by means of lateral forces exerted by resilient means (e.g. coil springs), so that the overall flatness of the printhead structure (106) becomes equal or better than 50 mu m. <IMAGE>
