摘要:
Continuous tone black and white images are duplicated using laser thermal digital halftone printing. A continuous tone black and white image signal is provided by a source such as a medical imaging source. The image signal is screened with a digital halftone screen, such that each pixel of said image signal is represented by a predetermined matrix of micropixels, whereby to produce a digital halftone image signal corresponding to the continuous tone black and white image signal. A master is created by printing the digital halftone image onto a dye ablated medium by means of laser thermal recording. A duplicate of the master is produced by contact printing onto a duplicating medium.

This invention relates to a thermal dye transfer assemblage comprising:a) a dye-donor element comprising a support having thereon a dye layer and an infrared absorbing material associated therewith, andb) a dye-receiving element comprising a support having thereon a dye image-receiving layer having a given image area, the dye-receiving element being in a superposed relationship with the dye-donor element so that the dye layer is adjacent to the dye image-receiving layer,the improvement wherein spacer rails having a height of about 3 to about 50 .mu.m are located between the dye-donor element and the dye-receiving element, the spacer rails being located just outside the image area of the assemblage in such a location so as to separate the dye-donor from the dye-receiver across the entire image area; andthe dye-donor element support and the dye-receiving element support either being rigid and flat or being held rigid and flat in the assemblage so that there is no more than an insignificant sag at the area midway between said rails.
摘要:
A dye-receiving element for thermal dye transfer suitable for forming a slide for projection viewing comprising a polymeric central dye image-receiving section and an integral polymeric frame section extending around the periphery of the central dye image-receiving section, the frame section being from about 1/2 to about 3 mm thick and the central dye image-receiving section preferably being thinner than the frame section. Such integral receiver-frames do not require post-imaging framing and mounting assembly operations in order to be viewable in slide projectors, and are particularly advantageously used in laser thermal dye transfer systems.
摘要:
A migration imaging system using a laser-addressable thermoplastic imaging member. The imaging member comprises a supporting section and a thermoplastic imaging surface layer. A charged, uniform layer of marking particles is deposited on the imaging surface layer. An imagewise-modulated laser beam transforms selected volumes of the imaging surface layer in an imagewise pattern to a permeable state. Charged marking particles that superpose a transformed volume then migrate into the imaging surface layer so as to be retained. Unaddressed marking particles are cleaned away. The imaging member, or solely the imaging surface layer, may be transferred and bonded to a receiver such as a drum for use as an exposure mask, or to a receiver sheet to provide a hard copy reproduction. The processed imaging member is usable as a master in a xeroprinting system.
