摘要:
A dye-receiving element comprising a support having thereon a laser-induced thermal dye transfer image and spacer beads of such particle size and concentration that effective contact between the dye-receiving element and a dye-donor element is prevented during transfer of the laser-induced thermal dye transfer image.
摘要:
Photographic elements, assemblages and processes are described for producing a monochromatic dye image. The assemblage comprises:(a) a photosensitive element comprising a support having thereon a layer of nondiffusible dye image-providing material, a stripping layer, an opaque layer and a silver halide emulsion layer;(b) a transparent cover sheet; and(c) opaque processing composition for application between the element and cover sheet. A dye mordant layer may also be present on the element or cover sheet.After exposure and processing, the layer of nondiffusible dye image-providing material on a support is stripped away to provide a monochromatic retained dye image without the need for bleaching and fixing.
摘要:
An apparatus for offset lithographic printing including an offset lithographic printing press including a printing cylinder having a surface including a mixture of cationic colloidal silica, fumed alumina, and a polymeric amine; and an inkjet printhead disposed to print a digital image on the printing cylinder with an ink jet fluid including a pigment and a polymeric dispersing agent, which ink jet fluid dries to produce a surface active to oleophilic lithographic printing inks.
摘要:
An ink jet printing apparatus having a cleaning station that cleans the orifice plate with a cleaning liquid. The cleaning liquid includes a hydrophobic additive that has a strong affinity for the orifice plate material and which coats the orifice plate to form a protective coating. If a portion of the protective coating is removed, that portion will be repaired by the additive.
摘要:
A method for preparing a lithographic plate which can react with an imaging fluid to form an image, including providing a hydrophilic support; forming a fluid-receiving layer that includes a water-soluble material which is chemically reactive with the imaging fluid; imagewise applying the imaging fluid to the fluid-receiving layer; and drying or curing the applied fluid to form an image in the fluid-receiving layer.
摘要:
An ink jet print head is provided that includes a nozzle plate having an outer metal layer having nozzles for ejecting ink drops, and a coating of a non-wetting polymer chemically bound over the outer surface of the metal layer of the plate. Preferably, the polymer is a block polymer having a head that includes the chemical group that chemically bonds with the outer metal layer, and a tail that is hydrophobic. The resulting polymer coating prevents inks from pooling, drying, and creating deposits which would otherwise impede or clog the ink jet nozzles. The chemical bonding between the non-wettable polymer and the metal surface creates a highly durable polymeric layer that resists being wiped off during both printing and head cleaning operations.
摘要:
A display for presenting selected images to a viewer, including a transparent substrate; a transparent, electrically conductive coating formed over the transparent substrate; a light modulating layer formed over the transparent, electrically conductive layer; and a patterned conductive layer formed over the light modulating layer which provides viewable and conductive images, the light modulating layer being effective in two conditions, in a first condition to prevent the viewing of the viewable and conductive images and in a second condition to permit the viewing of the viewable and conductive images.
摘要:
A cleaning fluid for use with an inkjet printer having orifices for injecting ink, the surface of the orifices at the injection point being formed by a predetermined material includes a liquid for cleaning the surface of the orifices, such liquid including a di or trihydroxysilane which acts as a biocide, surfactant, and humectant.
摘要:
Apparatus for color printing on a re-inkable belt, the re-inkable belt being moveable along an endless path and trained about a transport roller and including an ink transfer layer where an ink can be transferred to a moveable receiver and the moveable receiver moves into ink transfer relationship with the re-inkable belt at a nip position for transferring ink imagewise from the re-inkable belt to the receiver. The depleted ink is replenished and the re-inkable belt is arranged so that ink will be diffused into the ink transfer surface, and tension is adjustedly applied at two spaced locations to the transport roller and including two spaced steering actuators which, when actuated, apply tension to opposite positions on the transport roller, a sensor for determining the position of the re-inkable belt, and a computer coupled to the sensor for selectively actuating the steering actuators so as to apply tension to the transport roller which compensates for lateral distortion of the re-inkable belt.
摘要:
A method for microfluidic printing continuous tone color pixels on a reflective receiver by using cyan, magenta, and yellow inks including supplying a fourth, colorless ink along with the cyan, magenta, and yellow inks needed for color printing; pumping the inks through capillary microchannels by microfluidic pumps; mixing the correct amount of colorless ink with the cyan, magenta, or yellow inks to produce both the correct hue and tone scale for each colored pixel; and transferring the colored pixels of mixed ink to the reflective receiver to form colored pixels on the receiver.
