摘要:
A method of storing an image produced by x-ray exposure and releasing the stored image is disclosed. It is disclosed to expose an x-ray storage screen, comprised of an isotropic storage phosphor and a polymer coated on a support, to x-radiation of a first wavelength in an imagewise manner to store an image pattern in the storage screen. The image pattern is retrieved from the storage screen by exposing the storage screen to radiation of a second wavelength, thereby stimulating radiation of a third wavelength. The polymer has an index of refraction which matches the index of refraction of the phosphor at the second wavelength, and the support is non-reflective to radiation of the second wavelength.

摘要:
A direct write lithographic printing plate includes a base layer; a metal light absorbing layer provided over the base layer; and a melanophobic layer provided over the metal absorbing layer and selected to have a thickness which minimizes reflection of light from the metal layer so that light which passes through a selected portion of the melanophobic layer and into the metal light absorbing layer, is absorbed by such metal layer to provide a heat source which causes the removal, at the selected portion, of the melanophobic layer.

摘要:
A lithographic imaging member has a support having thereon a melanophobic silicone copolymer layer and a contiguous surface melanophilic layer composed of an inorganic or organic polymeric matrix. Either or both layers includes a photothermal conversion material capable of converting irradiation, such as IR radiation, to heat in exposed regions. The imaging member can include in one or more layers a material capable of promoting adhesion across the interface of the contiguous layers. This imaging member can be digitally imaged, for example using a laser, and used for printing without wet processing.

A flexographic imaging element comprises a support having thereon a relief imaging layer and a multi-level writeable mask layer. This mask layer is capable of multi-level communication with the underlying relief imaging layer so that the resulting image has continuous tone densities corresponding to the information written on the mask layer.

摘要:
A method of printing human readable information on a CD having a substrate, a record layer over the substrate, and a reflective layer over the record layer includes the steps of providing a colorant donor element in transferable relationship with a surface of the CD over the reflective layer; raster scanning a light beam across the colorant donor element to cause the transfer of human readable colorant pixels onto such surface; and continuously raster scanning the light beam without any non-printing or free fly time during the transfer of such human readable colorant pixels.
摘要:
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, the colorant element support being configured to provide a surface having peaks and valleys; pressing the colorant element support surface against a rigid element so as to cause the colorant transfer layer surface to conformally have peaks and valleys; causing the peaks of the colorant transfer layer to engage the image-receiving element; and applying radiation to the colorant donor element to cause colorant to transfer in the space between the image-receiving element and the colorant transfer layer surface corresponding to the valleys in the colorant transfer surface.
