BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic plate making system for producing a printing plate for printing.

[0002]

2. Description of the Related Art In the plate making process for producing a printing plate for printing,
Printing plates such as photosensitive lithographic printing plates (hereinafter referred to as "PS plates")
The image recorded on the original film is printed by a printing device such as a stencil printing machine. The PS plate on which the image recorded on the original film is printed is subjected to development processing, and then carried to the printing step as a printing plate for producing printed matter. There has been proposed a breeding system that automatically performs a series of processes from the printing of the PS plate to the development.

Generally, in a positive PS plate, if the peripheral non-image portion remains unexposed, ink adheres during printing, and this ink appears as print stains on the printed matter, impairing the finish of the printed matter. Will end up. In order to prevent such print stains on the printed matter, an erasing process for exposing the non-image portion of the PS plate is performed.

When such a treatment is carried out by a plate making machine, after removing the original film, the mask is largely moved,
Mask the printed area of the original film, and
The periphery of the image area on the S plate is exposed side by side.

Further, when performing multicolor printing by an offset rotary press or the like, it is necessary to prevent color misregistration on the printed matter. In order to prevent the color misregistration of the printed matter, in the plate making machine, a register mark is provided at a predetermined position of the non-image portion of the PS plate. In the printing machine, the register mark printed on the printed matter given to the PS plate is read by a scanner or the like, and when there is a deviation in the register mark on the printed matter, this deviation is fed back to the printing machine to cause color deviation in the printed matter. The registration is made so that the above does not occur.

However, if an image is printed on the PS plate together with the image-printing process and the register mark is applied by the breeding machine, it takes time to prepare one printing plate, and the plate is smoothly processed in a short time. Difficult to make a printing plate.

On the other hand, when the PS plate having the image printed thereon is mounted on the plate cylinder of the rotary press, it is necessary to make the top and bottom of the images recorded on the PS plate coincide. For this reason, marking lines are engraved on the top side and the ground side of the PS plate, and when the PS plate is wound around the plate cylinder of the rotary press, the marking line on the top side and the marking line on the ground side are aligned with each other. This prevents the printed matter from tilting in the vertical direction.

Further, in order to obtain a printed matter with good finish quality, it is necessary to apply an appropriate amount of ink according to the image printed on the PS plate to the surface of the PS plate (press plate) at the time of printing. For this reason, the area of the image portion and the non-image portion of the PS plate is calculated prior to the printing process, and the amount of ink used for printing is determined. Such an amount of ink is P when the development processing is completed by the pattern area ratio measuring device.
The surface of the S plate is divided into a number of areas, and the area or area ratio to which the ink adheres at the time of printing in each area is calculated and determined.

The marking line marking on the PS plate on which such an image is printed and the calculation of the ink amount are performed off-line in addition to the plate making process. Therefore, P after plate making
The S plate processing and the actual printing work in the printing process are complicated.
