Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a layout device for printing plate making, and particularly to a device that performs layout according to the contents of a mount.

[Conventional technology]

In recent years, something called a layout computer has been used for layout work in printing plate making, and for example, a layout scanner device equipped with an input/output scanner has been commercialized.

FIG. 6 is a block diagram illustrating the configuration of a conventional layout device for printing plate making shown in, for example, Japanese Patent Application Laid-Open No. 62-239664, where A is a plotting machine and B is a diagram using the plotting result of the plotting machine A. This is a device that performs trimming layout.

The drawing machine A includes a tablet digitizer 50 and a CPU 51 that operates in conjunction with the tablet digitizer 50.
．． Floppy disk device 52° plotter 53. Consists of a mask cutter 54, etc., and a tablet digitizer 5.
0 consists of a cursor 50a, an input surface 50b, and the input surface 50b has a mount area 50c, a first menu area 50d,
It has a second menu area 50e, where various commands are input.

l. The rimming layout device B includes an input drum 61, an output drum 62 . A scanner unit 65 with a linear encoder 63° and a rotary encoder 64, an interface circuit 66 and 67, a computer 6th, and a magnetic disk device 69
．． It consists of 70 mag.

Next, the general operations of the drawing machine A and the trimming layout apparatus B will be explained.

First, regarding plotting machine A, Tablet Digitizer 5
If the layout is set to 0, set the mount. The layout of the mount coincides with the mount area 50c in the figure, and has ruled lines indicating the area to be trimmed of the document and a simple figure indicating the outline of the picture.

Therefore, position data is input by aligning the cursor 50a with the ruled line of the trimming range. However, if the trimming range is one of several predetermined shapes, such as a rectangle, simple position data input can be performed.

In this way, when the input of the trimming range and the position data of the specific point is completed, the pattern assignment is input while touching the cursor 50a to the specific point of the reference person, for example, the inner corner of the eye.

Input using the tablet digitizer 50 is performed by the CPU.
5.1, it is stored in the floppy disk device 52. The stored contents are also given to the plotter 53 and mask cutter 54 and used for photographing and printing characters.

In the trimming layout device B, a computer 68 receives position data and layout data stored in the floppy disk device 52 of the drawing machine A, and processes image data from the input drum 61 of the scanner section 65.

A document is set on the input drum 61 of the scanner section 65,
The aim of a magnifying glass (not shown) is matched with a specific point on the document image. At this time, the outputs of the linear encoder 63 and rotary encoder 64 are the coordinates of the specific point on the original image,
Thereafter, when output is extracted by scanning by the scanner section 65, the specific point coordinates are used as a reference. That is, the image data taken out from the input drum 61 of the scanner section 65, together with the position signal from the linear encoder 63,
It is applied to a computer 68 via an interface circuit 67. The computer 68 processes the image data from the scanner section 65 based on the position data etc. from the floppy disk device 52, extracts only the image data included in the trimming range, and further makes corrections based on the layout data. The image data that has undergone these processes is written to the magnetic disk device 70.

The image data stored in this magnetic disk device 70 is
The output drum 62 is read out based on a read command from the computer 68 and sent to the output drum 62 via the interface circuit 66.
given to. A film is mounted on the output drum 62 in advance, and exposure is performed based on image data stored in the magnetic disk device 70. As a result, a film original plate with a trimmed layout has been created. This original film includes the original image, halftone dots,
Live lines etc. are printed.

In this way, plate-making work has become complicated. For example, a manuscript is submitted to the workshop with a rough mount (one that does not require as much precision as a sketch), and the magnification and angle of the manuscript are measured based on this rough mount. Processing is performed, and this document information is stored in the magnetic disk device 69. Until the mount is submitted, the formal layout of the images that will become the material for the printed matter is in progress, and the disk number where the input image data exists (contains multiple magnetic disk units 69), etc. Information necessary for proceeding in subsequent processes and completion information at the time of work completion are stored in the magnetic disk device 69. Next, when the official mount (layout is a mount) is entered, accurate layout position information is stored in the magnetic disk device 69 of the trimming layout device B using the drawing machine A or the digitizer attached to the layout system, and the trimming work is performed sequentially. finish.

In this way, when all the materials for the printed matter are prepared, the page make-up processing process is started. Here, the page make-up process refers to the process of accurately trimming the input image page by page based on the submitted position data and storing it in the magnetic disk device 70. Operators take turns to perform arbitrary page make-up on the same printed material by inputting necessary commands from an input section (not shown) of the trimming layout device B.

[Problem to be solved by the invention]

In this way, in the conventional layout device, the layout placed on the drawing machine A is done as desired by associating specific points on the mount with the image information of the document input from the input drum 61 of the trimming layout device B. It was configured to easily process and examine images of manuscripts.

However, the original images used in printing plate making are not always images parallel to the sides of the printing paper, but are often rotated in a predetermined direction or enlarged at a predetermined magnification of the original input image.

For this reason, conventionally, an operator has performed positioning processing and magnification processing of the input original image at a specified angle with respect to the input drum 62.

For this reason, there have been serious problems such as measurement errors by the operator affecting the input image and significantly deteriorating the print quality.

This invention was made in order to solve the above-mentioned problems.The layout is performed by specifying and inputting a plurality of specific points from a mount, and from the coordinate information of these plurality of specific points, angle information and magnification information necessary for layout processing are obtained. It is an object of the present invention to provide a layout device for printing plate making that can automate magnification/one-rotation layout processing of a document image input at a fixed position by automatic calculation.
