PURPOSE:To permit high-speed printing, high-density printing and high-picture- quality printing by a method wherein ink solution is absorbed or adhered to the liquid retaining film of a reticulated structure in a mist generating unit to generate ink mist by vibrating it. CONSTITUTION:The liquid retaining film of a reticulated structure, which is employed for an ink mist generating mechanism, is braided so as to have reticulated configuration by a fibrous substance 11 and accumulates ink drips 13 in cavities by the effect of capillary phenomenon when the ink solution is supplied. The ink drops 13, accumulated in the parts of the cavities, are discharged as ink mist by subjecting them to vibration. Accordingly, when lipophilic ink solution and hydrophilic ink solution are used for forming a picture under mist state, ink mist, small in the grain size thereof and sharp in the grain size distribution thereof, can be obtained in a big amount. On the other hand, the generating amount of the same may be increased whereby high-speed printing, high- printing-quality printing and high-picture-quality printing can be effected as a result. |
