    摘要: An aftertreatment apparatus, for printing plates which have been exposed imagewise comprises an exposure station and a heat station which are disposed one behind the other in the direction of conveyance of the printing plates along a conveyor track through the aftertreatment apparatus. The exposure station contains a regulable radiation source for the total area exposure of the printing plates. The housing of the exposure station has an exposure aperture 13 which faces downwardly and which is covered by a filter disc. The housing of the heat station is thermally insulated at three sides and is open downwards in the direction of a reflector table across which the printing plates are fed.

    摘要: A negative-working radiation-sensitive mixture comprising a binder and a polymer containing 1,2,3-thiadiazole groups is disclosed. The binder is a polyfunctional compound having functional groups that react with ketene. The polymer is a compound obtained by polymerization of a compound of the general formula I ##STR1## in which R is a polymerizable group. If the polymer is a copolymer containing comonomers having functional groups capable of reacting with ketene, the binder can be omitted. The negative-working radiation-sensitive mixture is particularly suitable for UV, electron beam and X-ray lithography.

    摘要: The invention describes a photopolymerizable recording material which comprises a photopolymerizable layer and a cover layer. The cover layer comprises a polymer which possesses low permeability to atmospheric oxygen and is soluble in water, and a water-soluble dye which absorbs light in the region from 300 to 700 nm and within this range has a non-absorbent region corresponding to the emission range of the copying light source.The material can be sensitized for various spectral regions, for example, for UV light, visible light or laser light and has a higher resolving power than a corresponding material which does not contain a dye in the cover layer, while its photosensitivity remains unchanged or is only slightly reduced.

    摘要: A laser exposure apparatus utilizing a laser, beam divider, modulator, beam expander, beam combiner, polygonal mirror and also a scanner lens, path-folding mirror and a reference mask. The laser beam is divided in the beam divider into a writing beam and a reference beam, both of which are brought together by means of two path-folding mirrors and a beam combiner. The writing beam is then guided through an exposure slit onto a printing form by a path-folding mirror. One additional exposure device is disposed upstream and/or downstream of the exposure slot, and in the direction of conveyance of the printing form. Only one of the additional exposure devices is switched on during operation, so that either a preexposure or an afterexposure is accomplished in addition to the laser main exposure of the printing form.

    摘要: The present invention relates to a process for preparing a multicolored proof, using a radiation-sensitive recording material which comprises a temporary, sheet-shaped layer support, a thermally transferable layer containing a colorant in one primary color and a radiation-sensitive layer. The process comprises the steps of: a) exposing the recording material imagewise b)developing the exposed layer with an aqueous-alkaline solution to uncover the thermally transferable image areas, and c) contacting the coated side of the recording material with an image receptor and transferring the transferable image areas to the image receptor, with the application of heat and pressure, to produce a partial image in the first primary color. The above-described process steps are repeated at least once, using a radiation-sensitive recording material which contains a colorant in another primary color in its thermally transferable layer. Depending upon the respective embodiment, the process of the invention yields a proof which can be produced by a positive, a negative or a digital method, without distorting the image thus generated by interjacent layers.
