[Prior art and its problems]

(1) In the platemaking field, an intaglio printing machine is used that prints an image of an original plate on a printing plate (an example of a photosensitive material) such as a PS plate or a photosensitive film in multiple faces. In this type of plate-making machine, an image portion is masked and a blanking process of exposing a blank portion of the image can be performed. When the burn-out process is performed, the margins are exposed, and the ink does not reach the margins during printing. Therefore, the amount of ink consumption can be suppressed and the printing cost can be reduced. Further, when the exposure and baking are completed, the development and gumming processing according to the type of printing plate are performed.

Conventionally, the burning-out is carried out by a plate-making machine. However, in the case of the plate-making machine, since the size of the original plate holder is relatively smaller than that of the printing plate, the burning-out work is troublesome and troublesome. In addition, various print management marks may be printed on the margin before the burn-out work, which further complicates the burn-out work. In particular, the print management mark is extremely smaller than the image of the original plate on which the printing plate is made,
It is inconvenient to handle the original plate in the same manner as a normal original plate, and the auxiliary plate for the original plate is wasteful.

An object of the present invention is to make it possible to easily carry out a burning operation and a printing operation of various mark images. (2) The printing plate, which has been exposed by the intaglio printing machine to form an image, is sent to an automatic developing machine and subjected to development processing and gumming processing. There are various developing methods depending on the type of printing plate, but conventionally, only one type of printing plate can be developed on the automated line, and many types of plate are handled on the automated line. It is difficult.

Further, although there are cases where various processes such as a burn-off process and a marking process are required prior to the development process for the plate after exposure, a structure in which a dedicated device for carrying out these processes is installed. Then, it is not easy to construct an automated line. Another object of the present invention is to facilitate line automation of plate processing.
