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.

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.

A microfluidic printing apparatus responsive to an image file for printing a plurality of pixels on a display is disclosed. The apparatus includes a plurality of ink delivery chambers; ink channels for delivering ink to each ink delivery chamber; and heater elements associated with particular delivery chambers and effective for causing the transfer of heat to inks in such chambers for regulating ink flow from the ink delivery chambers to the display. The apparatus further includes a circuit for controlling the heater elements for regulating the ink flow in response to the code values of the image file.
摘要:
An imaging member can be prepared by imagewise application of a fluid onto a water-soluble fluid-receiving layer coated on a hydrophilic support. Application is preferably accomplished by ink jet printing. The fluid is dried or cured to form an oleophilic image on the fluid-receiving layer. The fluid-receiving layer must form a contact angle of at least 20.degree. with the applied fluid. After removal of the non-imaged areas, the resulting imaging member can be used for lithographic printing.

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 and pumping the inks through capillary microchannels by microfluidic pumps. The method further includes mixing the correct amount of colorless ink with the cyan, magenta, or yellow inks to produce mixtures of ink having a desired correct hue and tone scale; and transferring the pixels of the ink mixtures to the reflective receiver to form colored pixels on the receiver comprising a support, a layer formed over the support of an ink impermeable material and cavities defined in a surface of the ink impermeable layer and an ink absorbing material disposed in the cavities for absorbing a determinable amount of ink until saturated such that ink is not conveyed to adjacent cavities.

A method of stabilizing a thermal image in an image receiving layer, includes: adding a reactive plastisizer which is capable of being cross-linked upon the application of radiation to the image receiving layer; transferring the thermal image to the image receiving layer; and applying radiation to the image receiving layer sufficient to cross-link the plastisizer and thereby stabilize the image.
摘要:
Apparatus for color printing on a moveable receiver includes a re-inkable belt including an ink transfer layer where an ink can be transferred; a structure for causing the moveable receiver to move into proximate contact with the re-inkable belt at a nip position for transferring ink imagewise to the moveable receiver; and an interface capillary spaced from the re-inkable belt and for receiving ink and including pumping structure operating on the ink in the interface capillary for forming a meniscus in such space which engages the re-inkable belt so that ink will be diffused into the ink transfer surface. The apparatus further forms a meniscus when the re-inkable belt passes by the interface capillary to cause ink to diffuse into the ink transfer layer when the ink transfer layer is saturated with ink.
摘要:
A method for transferring colorant from a donor element to a dye receiving layer to form a desired label includes providing an embossed surface on the dye receiving layer having desired spacing to minimize mottling; positioning the embossed surface of the dye receiving layer in the focal plane of a focused laser beam with a colorant donor element being positioned in transferable relationship with the dye receiving element; and focusing a laser beam on the colorant donor element to heat the donor element to a sufficient temperature to transfer colorant to the dye receiving element to thereby effect the transfer of colorant from the donor element to the dye receiving layer. The method also includes providing relative movement between the dye receiving layer and the laser beam and modulating the laser beam in correspondence with a data record, thereby effecting laser thermal colorant transfer to the embossed surface on the dye receiving layer from the donor element in correspondence with a desired label so that the embossed spacing provides a high quality mottle free label.
