PURPOSE:To prevent a trouble caused by defective sticking of a positive film by coating the upper surface of a photosensitive layer of the photosensitive intaglio printing material providing a substrate and the photosensitive layer with a transparent plastic film having the thickness of 1-50mum. CONSTITUTION:The upper surface of the photosensitive layer of the photosensitive intaglio printing material providing the substrate and the photosensitive layer is coated with the transparent plastic film having the thickness of 1-50mum, thereafter by image-wisely exposing the photosensitive layer through the transparent film. The used transparent plastic film has <=10% turbidity measured by the film having 25mum thickness, and is exemplified by a polyester film and a polypropylene film, etc. Thus, the reproducibility of the image is not practically reduced, and the uniform sticking of the positive film is obtd., even when the surface of the photosensitive layer of the photosensitive intaglio printing material has sticking property. |
