Abstract:
A printing device according to the present invention includes a dye tank for containing a powdered vaporizable dye, an entrance section for liquefying the powdered vaporizable dye and a vaporizing section for radiating a laser light beam onto the liquefied dye transported to it by the entrance section for vaporizing the liquefied dye for thermal transcription of the vaporized dye onto a photographic paper. In this manner, printing may be made without employing an ink ribbon or a thermal head and hence the saving in power and the reduction in size and costs of the printing device may be achieved. Besides, the printing time may be shortened, while the size of the printing paper may be set freely. A photographic paper according to the present invention includes a light absorbing layer between a receptor layer and a photographic paper base. Since the light absorbing layer is capable of absorbing the light efficiently for evolving heat efficiently, the receptor layer may be heated directly to assure a high quality of the printed picture.

Abstract:
A color video printer having a printer head portion and a cartridge detachable for supplying a solid dye to the printer head portion. The head portion vaporizes the solid dye and transfers the vaporized dye to a substrate. The cartridge is attached to the printer head portion when the supply of the dye is necessary. When the dye is supplied from the cartridge, the solid dye in the cartridge is liquefied and the liquefied dye is supplied to the printer head portion by capillarity.
Abstract:
An ink sheet (3) is wound around rollers (6), and a recording sheet (4) is placed with a space (d) between the ink sheet (3) and the recording sheet (4) and is advanced. The thickness of the space (d) is a value in the range of 1 to 100 .mu.m. The ink sheet (3) is irradiated with a laser beam (L) emitted by a laser (5) to transfer the dye contained in a dye layer formed on the ink sheet (3) from the ink sheet (3) to the recording sheet (4) for printing. The dye layer of the ink sheet (3) is replenished with the dye (30, 30A) heated and fused by a heater (9) by a dye supply unit (7) at a position other than a position where the ink sheet (3) is irradiated with the laser beam (L). Since the ink sheet and the recording sheet are held with the space (d) having a thickness in the range of 1 to 100 .mu.m, the dye once transferred to the recording sheet is not transferred from the recording sheet to the ink sheet, so that a clear picture having a comparatively high density can be printed. Since the dye layer of the ink sheet is replenished with the dye, the ink sheet can be repeatedly used, so that no waste is produced.
Abstract:
A laser sublimation type color video printer includes a plurality of dye tanks for accommodating solid powder form sublimating dyes. The dye tanks are communicated with liquid dye vaporizing sections via respective accommodating passages which are formed as capillary tubes provided with heating elements for liquefying dyes introduced from the dye tanks. The heating elements may also be active to heat the surface of photographic paper via a protective layer of the head portion of the printer. Each of the vaporizing sections comprises a plurality of vaporizing pores having a light-heat converting element projected thereinto from a head base of the printer. A laser source is mounted over the light-heat converting element, which may comprise a heat resistant light transmitting portion having a light-heat converting layer disposed on a lower end thereof. The vaporizing pores allow a sufficient amount of liquid dye to be adhered to the lower side of the light-heat converting element to be vaporized and adhered to the surface of the photographic paper upon irradiation by a laser beam from the laser source. An area of the light-heat conversion element is limited to an area which may be covered by the vaporized dye according to an irradiation operation.
Abstract:
A recording method of ink jet system which employs a recording solution composed of a dye which vaporizes more than 90 wt % upon heating at a temperature above 300.degree. C., leaving residues in an amount less than 10 wt %, and a solvent having a boiling point higher than 150.degree. C. which dissolves or disperses the dye more than 5 wt % at a temperature below 50.degree. C., the recording solution being heated at the time of recording by the recording solution heating unit which has a porous structure formed thereon which is composed of fine parts whose dimension in the plane direction is 0.2-3 .mu.m and whose dimension in the direction perpendicular to the plane direction is 2-15 .mu.m. This recording method makes use of the advantage of both the thermal transfer system and the ink jet system. Thus, it realizes a high resolution and a gradation within a picture element, produces high-quality images promptly, permits the printer to be made small and light, involves no waste materials, permits printing on plain paper, and needs a less amount of power and running cost.
