摘要:
There are described a method and a device for finishing flexographic digital printing plates. The finishing device comprises: - an exposure chamber (5) hermetic to UV rays, wherein radiating of the plate (1) to be treated is carried out; - a plurality of UV-A LEDs and a plurality of UV-C LEDs, said LEDs being placed inside the exposure chamber so that that their radiating surface faces the surface of the plate to be treated and being suitable for radiating the plate to be treated; - means for relative movement between the plate being processed, said plurality of UV-A LEDs and said plurality of UV-C LEDs, suitable for moving the plate being processed or the plurality of UV-A LEDs and the plurality of UV-C LEDs along a feed direction (x).

L'invention concerne un procédé d'inscription d'une image source, dans lequel on réalise sous la forme d'une matrice de motifs élémentaires, une reproduction de l'image source. Le procédé comprend les étapes suivantes : - dépôt (401) sur un premier substrat (41) d'une première couche opaque (42) ; - gravure (402) de la première couche opaque (42), de façon à former une matrice de premières cellules (440) présentant chacune un parmi plusieurs premiers motifs prédéterminés ; - dépôt d'au moins une deuxième couche opaque (45) ; et - gravure de la deuxième couche opaque (45), de façon à former une matrice de deuxièmes cellules (470) présentant chacune un parmi plusieurs deuxièmes motifs prédéterminés, les motifs élémentaires étant définis par la superposition d'un deuxième motif et d'un premier motif. L'invention concerne également un support d'image obtenu à l'aide d'un tel procédé.
摘要:
A photoresist film and method of using the photoresist film is described. The photoresist film allows for fine-detail abrasive blasting of substrates without the use of organic solvents for development. The photoresist film can be formed without the use of a membrane or adhesive layer, both of which are typically used to secure one side of the photoresist film to a carrier and one side of the photoresist film to a substrate. The photoresist films of the present invention typically include an ethylene-vinyl acetate copolymer ("EVA"), a polyvinyl acetate ("PVAc"), and a photo polymer. Suitable photopolymers include polyvinyl alcohol photopolymers.

A method and apparatus for fabricating a vertical deposition mask capable of welding a mask sheet and a mask frame for preventing a large area mask from drooping due to the weight of the mask. The apparatus includes a tensioning device for tensioning a mask sheet and a welder for attaching a mask frame to a circumference of the mask sheet. The tensioning device includes clamps for supporting the mask sheet and tensioners coupled to the clamps for applying tensile force to the clamps and to evenly fix in place the mask sheet by the clamps.
