    Abstract: Device for exposing photopolymer printing plates consisting of: an under frame (1) with incorporated UV fluorescent tubes (7b), an obliquely mounted supporting plate (4) made of glass for supporting the printing plates, said supporting plate being provided with an orthogonal pattern (25, 26) of grooves - connected to vacuum pumps; a matt black sheet (9) arranged between the UV fluorescent tubes and the supporting plate; a lid (2) with incorporated UV fluorescent tubes (7a) which is pivotally connected to the underframe at a pivot (6) and which can be folded up on the one hand and laid flat on the underframe on the other hand; and a device (4) which moves back and forth on toothed racks (5) for fold- and bubble-free laying and simultaneous cleaning of a vacuum film (3), the printing plate being sealed from the supporting plate in a vacuum-tight manner by the vacuum film when the latter is laid on the printing plate.

    Abstract: O.Z. 0050/40603 An apparatus for exposing photopolymeric printing plates consists of a stand (1) having integral UV fluorescent tubes (7b), an obliquely arranged glass support sheet (4) ¢sic! for supporting the printing plates, the support sheet being equipped with an orthogonal pattern (25, 26) of grooves, connected to vacuum pumps, a matt black cloth (9) arranged between the UV fluorescent tubes and the support sheet, a lid (2) which is pivotable about a pivotal point (6), is connected to the stand and has integral UV fluorescent tubes (7a), the lid being capable of being swivelled upward on the one hand and laid flat on the stand on the other hand, and a means (4) which moves to and fro via toothed racks (5) and is intended for fold-free and bubble-free positioning and simultaneous cleaning of a vacuum film (3), the vacuum film giving a vacuum-tight seal against the support sheet when the printing plate is placed on top.
