Abstract

PURPOSE:To reduce a waste as much as possible and to check the decomposition quality of each document by providing a decomposed image data input means, a trimming graphic form data input means, a trimming graphic form assigning means, an assignment area generating means, and an image data layout means. CONSTITUTION:Decomposed image data is inputted from the decomposed image data input means 11 and stored in a 1st image data storage means 19. When graphic form data showing a trimming range is inputted from the trimming graphic form data input means 2, the trimming graphic form assigning means 3a assigns a specific assignment area and the assignment area generating means 3b generates a new assignment area by dividing the assigned area by a line nearby an assigned graphic. Then a next trimming graphic form is assigned and this operation is repeated to complete assignment. Further, the image data layout means 16 decides the layout of image data stored in the 1st image data storage means 19 and stores it in a 2nd image data storage means 20 and then the data is outputted by the image data output means 12. Consequently, the decomposition quality of each document can be checked.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automatic and simple assembly system that efficiently and automatically layouts and outputs image data of various manuscripts obtained by scanner input.

(Prior art) In recent years, along with the color separation of documents using scanners, printed matter 1
A layout system is used in the field of printing plate making that synthesizes one page's worth of image data through composite processing. This f-out system connects a computer with a page editing function to a scanner, and sends the image data captured by the scanner to the computer, and performs so-called make-up processing such as layout and halftone processing on each printed page. After that, it is output to a scanner.

By the way, in the above layout system, an original version for one page of printed matter with make-up is created, so if even one of the originals color-separated by the scanner has poor separation, one page of printed matter will be deleted. It is necessary to re-create the original plate for the first time, perform color separation again on the document with poor separation, and then perform makeup processing again. This not only increases the running cost of the expensive layout system, but also The created master plate is wasted, resulting in a large loss of exposure film used for creating the master plate.

Therefore, in order to avoid having to redo the makeup process due to poor document separation as described above, it is necessary to check the image data of each color-separated document before performing the makeup process.

To check the separation status for each document, the image data of the document that has been color separated and stored in memory is
A method of reading out each image one by one and outputting it on exposed film, or outputting the separated image data on exposed film at the same time as the scanner's color separation, and then checking the output film with a simple proofing device, a color printer There is a method of directly creating a color hard copy from the image data of each original document using a computer and checking it.

(Problems to be Solved by the Invention) However, in the method of outputting the image data of a document one by one onto an exposed film and checking it with a simple proofing device, the operator can arbitrarily select the document, and Since colors are output continuously, there is a problem that there is a large amount of unused area on the exposed film, which not only wastes the exposed film, but also requires time and effort to operate the simple calibration device. In addition, in the method using a color printer, the output size is fixed, so it is difficult to output each image of the original on a standard output paper, which requires expensive photographic paper.
There is a problem that output paper such as special paper is wasted.

The present invention has been made in view of the above-mentioned problems, and it is possible to efficiently arrange the images of each document to be output, minimize the waste of exposure film, etc., and check the decomposition quality of each document. The purpose is to provide a system.

The trimming figure allocation means 3a allocates one of the trimming figures inputted from the floppy disk drive 2 to a predetermined allocation area, and the allocation area generation means 3b allocates the area to which the figure has been allocated by the trimming figure allocation means 3a. The trimming figure allocating means 3a allocates the next figure to the generated new area, and by repeating this process, the floppy disk drive is allocated to the predetermined area. The trimming figures input from 2 are sequentially allocated. Then, the layout figure data created by the trimming figure layout means 3a is recorded on the floppy disk FD2 via the floppy disk drive 2. Reference numeral 4 denotes a console, which issues commands to the computer 3 to start operations, etc.

Reference numeral 11 is an input drum for taking in data from an original, 12 is an output drum for outputting color-separated image data of the original onto an exposure film, and 15 is an input/output computer.

An ink face 13 connects the input drum 11 and the input/output computer 15, and provides the input/output computer 15 with decomposed image data of the original read by a scanning head (not shown) disposed on the input drum 11. . 14

Next, the operation of the apparatus shown in FIG. 1 will be explained.

FIG. 2 is a flowchart for explaining the control operation of the computer 3 shown in FIG. 1, and the process of allocating trimming figures for each document will be explained below based on the figure.

First, trimming figure data corresponding to a specified document is read out from the floppy disk 21 port 1 via the floppy disk drive 2 (Sl), and pre-specified data is extracted from the read data (S1).
2). The data to be extracted can be specified when measuring the magnification with the magnification measuring device 1 or when the combinator 3 reads the floppy disk F.
The operator performs this after reading the data from the DI.

Next, sort the extracted trimming shapes in order of size (S3), and search for a portion (hereinafter referred to as "margin") on the left side of the entire area where the shapes are to be allocated (S4), if there is a margin. It is determined whether the area exists (S5), and if it does not exist, the area is updated (S6).
, if it exists, search for a figure that fits in this margin (S7),
It is determined whether the corresponding figure exists (S8).

In this case, since the figures are sorted in order of size in step S3, the determination can be made quickly. If the corresponding figure does not exist, the process ends (S9); if it does exist, the corresponding figure is allocated to the margin found in step S4, and then a new margin is generated (SIO). A new margin is generated by dividing the area by lines that are close to the allocated figure and parallel to its outline. It is determined whether or not the smallest figure among the figures that have not yet been allocated can fit into this generated new margin (S11).
If it does not fit, merge this new margin and create a new margin (S12), and if it does, do not merge,
The margin generated in step SIO is registered as a margin for allocating the remaining figures (513), and the process returns to step S4 to allocate the next figure.

FIG. 3 is a schematic diagram showing an example in which trimming figures are allocated to allocation areas as described above, and the step operation shown in FIG. 2 will be specifically explained below based on the figure.

First, in step S3, as shown in FIG. 3(a), figures 11 to F50 are sorted in order of size. Now, suppose that the figure F1 is allocated to the partial area E1 of the allocation area, and no figures are allocated to the partial areas E2 and E3, as shown in FIG. is found, and in step S7, figure F2 is found, and in step SI
In O, the figure F2 is allocated to the partial area ε2 as shown in FIG. Then, partial area E2 is further divided into partial areas B2a 5E2b and ε2C by lines jl and f12 that are close to figure F2 and parallel to its outline line, and the area to which figure F2 is not allocated is wiped in step 313 as a new margin. be registered. In addition, as shown in Fig. 3(e), figure FX is allocated and partial area EX is
and BY are generated as new margins, but if the partial area BY is too small to fit the remaining figure, step S12
Accordingly, partial areas EX and BY are merged, and a new partial area E2 is registered as a new blank space in step S13.

FIG. 4 is a schematic diagram showing an example of allocating trimming figures as described above, and as shown in the figure, drawn figures of different sizes are arranged without gaps in a predetermined area 3.

The trimming graphic data of each document laid out in this manner is recorded on the floppy disk FD2 via the floppy disk drive 2, and provided to the layout computer 16 via the floppy disk drive 5.

The layout combiner 16 uses the trimming figure data recorded on the floppy disk FD2 to
The image data of the corresponding document is read out from the image data of each document stored in the magnetic disk 19, and its layout is performed. The laid out image data is once stored on the τ air disk 20, then read out by the input/output computer and output onto the exposure drum 12 via the interface 14 to create an original. Here, it is assumed that the image data of each document is stored in the magnetic disk 19 in approximately the same size as the trimming range, and in the layout computer 16, the center point of the trimming figure and the center point of the image of the corresponding document are stored. By matching the images, the image data of each document is positioned.

Note that in this embodiment, the floppy disk FDI
The trimming figures recorded in are rectangular, and each trimming figure allocated by the computer 3 is parallel to the reference line, but in the present invention, the shape of the trimming figure is limited to that of the above embodiment. Instead, it may be a circle, a polygon, etc., and the trimming figure may be laid out at a certain angle with respect to the reference line of the trimming figure.

However, if the allocated trimming figure is not a rectangle parallel to the reference line, in the trimming figure allocation process shown in Figure 2, each trimming figure is will be allocated.

Further, the image data output means of the present invention is not limited to the means for creating an original shown in the above embodiments, but may be a color printer or the like.

(Effects of the Invention) As described above, in the present invention, a photographic original is color-separated at a predetermined magnification ratio and separated image data is input from the separated image data input means, and the input separated image data is used as the first image. The data are sequentially stored in the data storage means. When graphic data indicating a trimming range for a plurality of documents is input from the trimming figure data input means, the trimming figure allocation means allocates the input trimming figures to a predetermined allocation area, and generates an allocation area. The trimming figure allocation means generates a new allocation area by dividing the area to which figures have been allocated by the trimming figure allocation means along lines close to the allocated figures, and the trimming figure allocation means applies the trimming figure allocation means to the new allocation area generated by the allocation area generation means. assigns the next trimming figure, and by repeating this process, a plurality of trimming figures are efficiently arranged without gaps, and the image data layout means arranges the first image based on the layout figure data created by the trimming figure allocation means. After the layout image data created by the image data layout means is stored in the second image data storage means, the image data output means outputs the layout image data to the second image data storage means. Since the stored image data is output, the images of each document to be output are efficiently arranged without any gaps, and the effect is that it is possible to check the decomposition quality of each document while minimizing waste of exposure film, etc. .
