Printer with micro-tunnel print head

摘要

the printer has a recording surface (26a), a print head (132) positioned next to the recording surface and with at least one micro-tunnel (150). Each micro-tunnel contains an anode (160) placed next to the recording surface and a cathode (162) which is further from the recording surface than from the anode so as to form a gas plasma between the anode and the cathode. A lower layer (26b) at a constant voltage is arranged beneath the recording surface. The recording surface consists of a dielectric material and moves in a direction which is perpendicular to a number of adjacent micro-tunnels. A current source alters the anode voltage to enable the image to be recorded on the recording surface.
