2. Description of the Related Art In general, a printing apparatus used in a printing plate printing process is required to position an original plate and a material to be printed (for example, a plate material coated with a photosensitive agent) with high precision. Significant work relies on human labor. For this reason, it has been pointed out that the efficiency and automation of the entire printing plate printing process cannot be achieved, and various devices have been proposed to solve this problem.

More specifically, a single master is attached to a light-transmitting base member, and a pin provided in the master arrangement portion is fitted into a hole formed in the base member so that the base is fitted to the base. The member is positioned. On the other hand, a material to be baked is adsorbed and supported at the printing position, and a holder member provided with a suction means sucks and holds the base member and superposes the base member on the material to be baked supported at the printing position. A printing process is performed on the original under the urging action of the exposure unit.

[0004]

In the above-mentioned apparatus, however, it has been pointed out that when a plurality of different original plates are printed on a single material to be printed, the operation becomes considerably complicated. That is, a description will be given of a so-called four-type four-imposition method in which four different originals are baked once on a single material to be printed. First, the first base member to which the first type original is adhered is the original. It is arranged in the arrangement part. Next, a holder member sucks and holds the first base member and superimposes the first base member on a desired portion of the material to be printed, and performs a printing process corresponding to the first type original plate. The first base member after the completion of the printing process is held by the holder member and transported to the original discharging portion, while the second base member to which the second type original is adhered is arranged in the original disposing portion. You. The second base member is held by the holder member and is superimposed on a desired portion of the material to be printed, and after being subjected to a printing process, is conveyed to the original discharge section. Further, a third base member having a third type of original attached thereto is disposed on the original arrangement portion, and a printing process is performed for the third type of original in the same manner as described above. The member is discharged to the original discharge section, and then a printing process is performed on the fourth base member to which the fourth type of original is adhered.

Therefore, in the above-mentioned prior art, when performing four types and four impositions on a single material to be printed, it is necessary to make the holder member reciprocate four times between the original placement portion, the printing position, and the original discharge portion. And it takes considerable time and effort.
As a result, there is a problem that an efficient automatic printing operation is not performed, and the operation is actually dependent on a manual operation of an operator.

The present invention solves this kind of problem. It is possible to easily and quickly print a plurality of different masters on a single material to be printed, thereby improving the efficiency and automation of the entire printing operation. It is an object to provide a possible automatic printing method.

[0007]
