A method for the preparation of a lithographic printing plate comprises forming an oleophilic image on the surface of a hydrophilic support by depositing, preferably by ink-jetting, the desired image on the surface using an aqueous emulsion of an organic film-forming polymer which has been prepared by emulsion polymerization, whereby the polymer adheres to the surface of the printing plate forming an oleophilic film. The polymer preferably has functional groups such as sulphonate that bind the polymer to the hydrophilic surface. Preferably the polymer has a glass transition temperature of not greater than about 105&deg; C. and where the glass transition temperature is above 50&deg; C. the polymer, after deposition on the plate, is preferably subjected to a heat treatment to assist in film formation.

Lithographic printing plates and method for their preparation

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.

Ink jet receiver sheet with removable ink delivery layer

A method for making a lithographic printing plate comprising exposing a support, a melonophilic layer and a melonophobic layer, the latter containing crosslinked colloids to a laser beam having an intensity greater than 0.1 mW/.mu..sup.2 for a time sufficient to give a total exposure of about 200 milliJoules/cm.sup.2 or greater. Good printing steps and long running plates are produced.

Method of imaging lithographic printing plates with high intensity laser

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.

Imaging and printing methods to form fingerprint protected imaging member

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.

Imaging and printing methods to form imaging member by fluid application

An imaging member can be prepared by imagewise application of a mixture of a sol precursor in a liquid to a suitable substrate. Application is preferably accomplished by ink jet printing. Upon removal of the liquid, such as by drying, an insoluble, crosslinked polymeric sol-gel matrix is formed that will accept a lithographic printing ink. The resulting imaging member can be used for lithographic printing.

A direct write lithographic printing plate comprises a support, a melanaphilic layer, a melanophobic layer with a non-ionic crosslinker and a melanophobic layer with an ionic crosslinker. The plates are long running plates,

Direct write lithographic printing plates

A method of producing a radiation-induced colorant transfer image on a support, includes the steps of: providing an image-receiving element comprising a support having thereon an image-receiving layer; providing a colorant donor element having a colorant transfer layer on a colorant element support and wherein colorant can be transferred from a transfer surface of the colorant donor element to the image-receiving element in response to selectively applied radiation; providing a uniformly reflecting opaque element that is sufficiently opaque to radiation at the wavelengths of the radiation source; causing the image-receiving element to be contacted with the colorant donor element and these elements to be positioned between the radiation source and the uniformly reflecting opaque element; and applying radiation to the colorant donor element to cause colorant to transfer to the image-receiving element.

Uniform background for color transfer

A method of making black matrix grid lines for a color filter array for use with a liquid crystal display device or the like, comprising providing a photo-thermally sensitive black layer over a support layer; exposing a pattern of electromagnetic radiation onto the photo-thermally sensitive black layer corresponding to the desired pattern of the black matrix grid lines; and peeling off the unexposed portions of the photo-thermally sensitive black layer to thereby form the grid lines.

Method of making black matrix grid lines for a color filter array

A method for preparing a color filter array element is diclosed which includes the steps of forming an assembly by providing a support on which is coated a polymeric dye image-receiving layer; a stencil pattern on the dye image-receiving layer with holes corresponding to the desired color pixel array pattern; and a dye donor sheet over the stencil. The dye donor has a support film overcoated with a mixture of color dye, polymeric binder, and light absorber. The method further includes exposing the assembly to high intensity light to briefly heat the dye layer and thereby transfer the dye from the donor to the polymeric dye receiving layer so that a colored pattern of pixel elements are formed in or on the image-receiving layer.
