Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic printing method for automatically printing an original image by superimposing an original on a printing material, for example, a printing material coated with a photosensitizer.

[0002]

2. Description of the Related Art Generally, a printing apparatus used in a printing plate printing process is required to position an original plate and a material to be baked (for example, a plate material coated with a photosensitizer) with high accuracy. A lot of work relies on manpower. 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 conventionally proposed in order to solve this problem.

Specifically, a single original plate is attached to a translucent base member, and a pin provided in the original plate arrangement portion is fitted into a hole formed in the base member to form a base. The member is positioned. On the other hand, at the baking position, the material to be baked is adsorbed and supported, and the holder member provided with the adsorbing means adsorbs and holds the base member to superimpose the base member on the material to be baked supported at the baking position. The printing process is performed corresponding to the original plate under the biasing action of the exposure section.

[0004]

It has been pointed out that, in the above apparatus, when a plurality of different original plates are printed on a single material to be baked, the work becomes considerably complicated. That is, a description will be given of what is called four-type four-sided imprinting, in which four different original plates are baked once on a single material to be baked. First, the first base member to which the first-type original plate is attached is the original plate. It is placed in the placement section. Next, the holder member sucks and holds the first base member, superimposes the first base member on a desired portion of the material to be baked, and performs a baking 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 conveyed to the original plate discharge unit, while the second base member to which the second type original plate is attached is arranged in the original plate arrangement unit. It Then, the second base member is held by the holder member, superposed corresponding to a desired portion of the material to be baked, subjected to the baking process, and then conveyed to the original plate discharge part. Further, a third base member having the third type original plate adhered thereto is arranged in the original plate arrangement portion, and after the baking process is performed corresponding to the third type original plate in the same manner as described above, the third base member is printed. The member is discharged to the original discharge unit, and then the baking treatment is performed on the fourth base member to which the fourth type original is attached.

Therefore, in the above-mentioned prior art, when carrying out four kinds of four imposition on a single material to be baked, it is necessary for the holder member to reciprocate four times to the original plate disposing portion, the baking position and the original plate discharging portion. However, it takes a considerable amount of time and effort.
As a result, an efficient automatic printing work is not performed, and in reality, it depends on the manual work of the worker.

The present invention solves this kind of problem, and enables a plurality of different original plates to be easily and quickly printed on a single material to be printed, and the efficiency and automation of the entire printing operation can be improved. The purpose is to provide a possible automatic printing method.

[0007]

In order to solve the above-mentioned problems, the present invention provides a process of arranging at least two or more original plates in an original plate disposing section, and the two or more original plates through a holder member. , And a process of transporting the material to be baked to a baking position where the material to be baked is moved, and the two or more original plates and the material to be baked are relatively moved, and a desired original plate of the material to be baked is Repeating the process of performing the baking process in a state of overlapping the corresponding part and shielding the part of the material to be baked other than the part corresponding to the desired original plate, and the baking process according to the number of the original plates. According to the above, a step of performing a baking process on the material to be baked corresponding to all of the two or more original plates is provided.

[0008]

In the automatic printing method according to the present invention, at least two kinds of original plates are superposed on the material to be baked arranged at the printing position while being integrally held by the holder member. Then, after a desired original plate is overlaid on a predetermined portion of the material to be baked and the desired original plate is subjected to the baking process, the baking process is continuously repeated according to the number of the original plates. Therefore, it is possible to efficiently and automatically perform printing on various different original plates.
