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.

A liquid crystal dispersion display including an opaque first conductive layer including developed silver crystals and having a plurality of first openings for transmission of light; a water permeable coated layer having dispersed liquid crystals in a binder over the opaque first conductive layer; an opaque second conductive layer including developed silver crystals coated over and coextensive with portions of the opaque first conductive layer and formed with second openings which are offset from the first openings; and a structure for changing the electrical potential between the first and second conductive layers so as to effect a change in the dispersed liquid crystals which in a first state causes light which passes through the first openings to be absorbed by the second conductive layer and in a second state which causes light to be scattered and passed out through the second openings in the display.

摘要:
A method for microfluidic printing comprising pumping and mixing colored inks which comprise a mixture of colorants, fluids, and gel-forming or gel-initiating ingredients to form ink pixels and to transfer such ink pixels to a receiver transferring position; and transferring the ink pixels to a reflective receiver which contains gel-forming or gel-initiating ingredients so that the ingredients in the transferred ink pixels and in the receiver react to form a gel and the viscosity of the transferred ink rapidly increases to limit the flow of ink pixels whereby such ink pixels are fixed to the receiver and overprinting of colors is minimized.
摘要:
An ink jet receiver which provides variable dot sizes, comprising a substrate, an ink-receiving layer disposed over the substrate, and a removable ink delivery layer which, in response to a droplet of ink, absorbs a portion of the ink and delivers another portion of the ink to the ink receiving layer so that a dot is formed in the ink-receiving layer.
摘要:
A drop-on-demand ink jet printing apparatus for printing proof images and then producing at least one lithographic printing plate in response to an input image includes a computer adapted to receive the input digital image and a plurality of ink reservoirs for providing inks of different colors for printing proof images and at least one lithographic ink reservoir for producing a lithographic printing plate. First print heads coupled to a proof image receiver and responsive to the computer for transferring particular inks onto the proof image receiver for producing proof images; and a second print head responsive to the computer for transferring lithographic ink from the lithographic ink reservoir to form an image pattern on the lithographic printing plate.
摘要:
A precursor element for making a lithographic printing plate is composed of a support, an ink receptive thermal conversion inner layer and a sol-gel, ink repellent outer layer. The outer sol-gel layer containes crosslinked colloids derived from certain metal oxides or hydroxides. The plates produced from the ellements are long-running plates that require no post-imaging processing.
摘要:
A display apparatus responsive to an image file for displaying a plurality of pixels including a plurality of ink display chambers; ink channels for delivering melted inks to each ink display chamber; and first heater elements for melting solid ink which is to be delivered through the ink channels to the display chambers. The apparatus further includes second heater elements for melting solid ink in the display channels after an image has been displayed; and a computer for controlling the first heater elements for causing solid ink melted by the first heater elements to be delivered to the display chambers where it solidifies to form a display of an image and for controlling the second heater elements for melting solid ink in the chambers to discard ink in the display chambers whereby the display apparatus is conditioned to form a new display image.
摘要:
Apparatus for printing on a moveable receiver images corresponding to a digital image includes a re-inkable belt which includes a polymer support layer and an ink transfer layer having a plurality of colored patches provided over the polymer support layer wherein ink can be transferred to and from the ink transfer layer, the polymer support layer including heating elements disposed in the colored patches in the re-inkable belt which, when a potential is applied to them, heats their corresponding patch the ink transferable layer to facilitate ink transfer. The apparatus selectively applies potential to the heating elements in the re-inkable belt at an image transfer system and causes the moveable receiver to move into proximate contact with the re-inkable belt at an image transfer position. The apparatus further applies energy to selected heating elements to heat an appropriate patch of the re-inkable belt at the image transfer position to facilitate ink transfer and responsive to the digital image to imagewise transfer ink from the re-inkable belt to the receiver.
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. After removal of the non-imaged areas, the resulting imaging member can be used for lithographic printing. The fluid-receiving layer is designed to protect the resulting imaging member from fingerprints or other handling defects.
