Abstract: A method of ink-jet printing is carried out by focusing a light beam from a quantum generator onto an expendable liquid printing material in a jet from the direction of the open end of the jet, with an information carrier placed in front of the open end, in order to generate a pressure pulse ensuring the expulsion of a droplet of the liquid onto the carrier. The method is carried out by directing the light beam onto the material in a jet either at an angle to its surface between the jet and the carrier, or through a carrier which is transparent to the wavelength of the beam. An ink-jet printing head has rows of jets, each with one blind end formed in the body of a driving drum.

Abstract: A photoconductive layer is formed on the entire outer peripheral surface of a light transmissive drum, and a conductive layer is formed on the photoconductive layer and is made up of a plurality of strip-like conductive portions. Provided around the drum are a tank for storing thermo-melting ink, a blade which removes surplus ink on the outer peripheral surface of the drum, a drier for drying the ink filling the gaps between the conductive portions in the conductive layers, a platen roller which presses against the outer peripheral surface of the drum with a sheet of recording paper in between, and a light source which is provided inside the drum, facing the inner peripheral surface thereof.

Abstract: A new printing system for drop on demand printing divides the printing process into two stages: a drop selection stage to select drops to be printed which generates a difference in meniscus position between selected drops and unselected drops of fluidized ink; and a drop separation stage, attracting the ink of the drops to a substrate, the attraction being insufficient to overcome the surface tension of drops in an unselected meniscus position but being sufficient to overcome the surface tension of drops in a selected meniscus position so as to cause movement of the drops to the substrate. The drop selection stage produces a difference in meniscus position in the absence of the drop separation stage. The separation of the drop selection stage from the drop separation stage significantly reduces the energy required to select which ink drops are to be printed. Only the drop selection stage must be driven by individual signals to each nozzle.

Abstract: During the recording where a liquid dye 22 supplied through a dye passage 27 is supplied to a vaporizing means 17 due to the capillarity of many small columns 21 within a vessel formed by coupling of a glass base 14 and a Teflon protection plate 290, the liquid dye in the vaporizing means is vaporized by irradiation of the laser beam L and the vaporized dye is transmitted to a photographic paper 50 passing a vaporization hole (aperture) 23 for the purpose of recording. The protection plate 290 has a critical surface tension against the liquid dye which is smaller than a surface tension of the liquid dye.Since the critical surface tension of the protection plate 290 is set smaller than a surface tension of the liquid dye, wettability of the liquid dye against the internal wall surface of the vaporizing hole 23 is low and the liquid dye left unvaporized at the vaporizing hole 17 at the time of recording is never deposited on the internal wall surface of the vaporizing hole.
