Abstract:
A print head (24) is disclosed for use in a marking apparatus in which a propellant stream (A) is passed through a channel (34) and directed toward a substrate (38). Marking material (28), such as ink, toner, etc., is controllably introduced into the propellant stream (A) and imparted with sufficient kinetic energy thereby to be made incident upon the substrate (38). A multiplicity of channels for directing the propellant and marking material allow for high throughput, high resolution marking. Multiple marking materials (28C, 28M, 28Y, 28K) may be introduced into the channel (34) and mixed therein prior to being made incident on the substrate (38), or mixed or superimposed on the substrate (38) without re-registration. One example is a single-pass, full-color printer.
Abstract:
A marking apparatus is disclosed in which a propellant stream is passed through a channel and directed toward a substrate. Marking material, such as ink, toner, etc., is controllably introduced into the propellant stream and imparted with sufficient kinetic energy thereby to be made incident upon a substrate. At sufficient velocity, and with appropriate marking material, the marking material may be kinetically fused to the substrate. A multiplicity of channels for directing the propellant and marking material allow for high throughput, high resolution marking. Multiple marking materials may be introduced into the channel and mixed therein prior to being made incident on the substrate, or mixed or superimposed on the substrate without re-registration. One example is a single-pass, full-color printer.
Abstract:
The present invention is a novel multiple laser diode structure and method for using such structures to optically isolate the light from the different diodes. The novel structure comprises a submount on which the individual lasing elements are mounted and a back facet monitoring plate coupled to the submount. The back facet monitoring plate comprises a plurality of optically sensitive detectors that monitor the amount of laser light emanating from the back facet. Ideally, one detector should be mounted opposite a back facet for each lasing element. The submount is designed with an isolation bar that optically separates the light from individual lasing elements. The radiation thus detected by each detector emanates from the back facet of a single lasing element. The amount of back facet radiation captured by the detector is proportional to the amount of radiation emanating from the front facet of the lasing element. This information enables the system to individually monitor and subsequently control the spot power of the lasing element in a continuous closed loop fashion.
Abstract:
An imaging member comprising a substrate, an electrically insulating swellable, softenable layer on the substrate, the softenable layer having particulate migration marking material located at least at or near the surface of the softenable layer spaced from the substrate, and a protective overcoating comprising a film-forming resin, a portion of which extends beneath the surface of the softenable layer. This migration imaging member may be prepared with the aid of a material which swells at least the surface of the softenable layer to allow the film-forming resin to penetrate beneath the surface of the softenable layer.
Abstract:
PROBLEM TO BE SOLVED: To provide a method of leveling an ink on a substrate, and apparatus that is useful in printing and can generate quality printed images on many kinds of substrates.SOLUTION: The method includes a step of irradiating the ink 144 disposed on a first surface of a porous substrate 140 with radiation 122 emitted by at least one flash lamp. The radiation flash 122 heats the ink 144 to at least a viscosity threshold temperature of the ink 144 to allow the ink 144 to flow laterally on the first surface to produce leveling of the ink 144. The ink 144 is heated sufficiently rapidly, heat transfer from the ink 144 to the substrate is sufficiently small during the leveling, the ink 144 on a substrate interface is cooled to a temperature below the viscosity threshold temperature, thereby preventing any significant ink 144 permeation into the substrate 140 from the first surface.

PROBLEM TO BE SOLVED: To provide a chemical composition or the like which enhances the image quality when the composition is applied to a substrate before printing. SOLUTION: The method for treating a substrate for ink jet printing comprises applying a chemical composition for image quality enhancement to the substrate from a channel with a nozzle and discharging an aqueous ink, in a specified pattern, to the image receiving face of the treated substrate from an ink jet head so as to form an image which has a high optical density, a minimum extent of curling, long-lasting water resistance and light fastness.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for forming the electronic color photograph of a full process color by which perfect image registration is obtained at high speed. SOLUTION: This method is a color printing image forming method by a single pass in which two electronic color photograph producing engines 8 and 9 equipped with three developing housings respectively are used in tandem constitution. In the mechanism 8; two developed images whose potential levels are different and one virtual image are formed on an electrified intermediate transfer belt 102 by using a wavelength ROS device 24, and the developed images are respectively developed by developing stations C and D and a latent image is developed by a developing station G after modification and transferred to the belt 102. The same processing is performed in the engine 9. One kind of color ink used for development in the engine 9 is made the same as color toner in the engine 8.
