    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: 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: 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.
