Problems solved by technology

However, since the support body of the lithographic printing plate is sometimes pre-cut into a plate shape, there is no specific proposal for forming a fine pattern on such a plate-shaped support body by the above-mentioned respective methods.
Therefore, it is practically impossible or extremely difficult to apply the structures described in the above publications to the plate-shaped support body, and even if it can be applied, it may lead to complex equipment or lower productivity.

Embodiment

[0068] The following examples illustrate the present invention in more detail, but the present invention is not limited to these examples.

[0069]In this example, the distribution, the diameter of the matting particles, and the matting height of the matting layer obtained by the matting treatment using the coating and drying device 12 of the above embodiment were measured.

[0070] First, as the coating conditions and drying conditions, set as follows:

[0071] Coating conditions:

[0072] Transport speed: 8m / min

[0073] Processing capacity: 6 pieces / min

[0074] Use spray gun: WA100-132P (made by アネスト Iwata)

[0075] Spray amount of coating liquid: 5.5 g / piece

[0076] Drying conditions:

[0077] Drying temperature: 80℃ (ambient temperature in the drying device)

[0078] Drying time: 15 seconds

[0079] As the aluminum plate 14, a test piece having a length of 200 mm and a width of 770 mm was prepared, and the test piece was coated in a range of 500 mm in the conveying directio...

Abstract

A coating / drying apparatus capable of certainly coating a sheetlike object to be coated with a coating solution by simple constitution to dry the coated object 14. The coating / drying apparatus 12 is provided with a bar conveyor 18 and an aluminum plate 14 is fed in a constant direction by the circulation of the bar conveyor 18. A coating device 30 and a drying device 32 are arranged above a frame 16 successively along a feed direction and the aluminum plate 14 is coated with the coating solution to be dried.

Description

Technical field [0001] The present invention relates to a coating and drying device for applying a desired coating material to a plate-shaped coating object and drying it. This coating and drying apparatus is used, for example, to provide a so-called matte layer to a flat printing plate. Background technique [0002] In printing using a flat printing plate, in the process of forming an image on the flat printing plate, most of the film manuscripts are stacked on the flat printing plate, and the flat printing plate is exposed through the film manuscript. At this time, it is best to make the film manuscript adsorbed on the lithographic printing plate to avoid the blur of the image when exposed to light. The film manuscript is adsorbed on the flat printing plate, and suction devices such as a pump are generally widely used to suck out the air existing between the flat printing plate and the film manuscript. Therefore, it is best to form a tiny pattern consisting of coated and non-co...
