Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an automatic trimming layout method for printing plate making, and in particular, 11! This invention relates to a method of trimming and laying out data at a desired position.

[Technical background]

2. Description of the Related Art In recent years, layout apparatuses that use computers to perform layout work necessary for printing plate making have come into widespread use. In this device, a document is generally attached to a zero-drum type scanner, the document surface is scanned, and the image data read is temporarily stored in a memory such as a magnetic disk, and the stored contents are used for subsequent layout processing. conduct.

That is, first, the image data that has been imported into the memory in advance is retrieved and displayed on the display screen, and the cursor representing the trimming range and the image of the document are arbitrarily moved on this screen to the position specified on the layout sheet. The images of a predetermined manuscript are sequentially inserted. As a result, the necessary range of the original image is trimmed, and this is allocated to the designated position on the image surface of one page.

However, in this method, specifying the position on the display screen is difficult and requires skill and time, and furthermore, positional errors are likely to occur. Therefore, accurate layout is difficult, and a display device with special functions for layout is required, which tends to result in an expensive device.

In addition to the above method, there is also a method in which, when reading the original image with a scanner, the size data of the part of the original to be trimmed and the position to be trimmed on the scanner are specified in advance using a keyboard, etc., and then the image data is read. Are known.

However, this method also has the drawback that it requires a great deal of skill and time to measure dimensions and specify positions.

[Purpose of the invention]

The present invention has been made by reconsidering the above-mentioned points, and an object of the present invention is to provide an automatic trimming layout method that can perform simple and accurate layout in a short time without requiring a special layout display.

[Summary of the invention]

In order to achieve this objective, in the present invention, a layout mount is set on a data tablet, and layout information including the image layout position 3 and the position data of the trimming range, as well as the magnification according to the required hair, is input, and this layout 1i [Based on the above, cut out the mask film with a mask cutter or plot on a transparent film plate with a plotter to create a mask plate that is the same as the input size of the original, and paste the original onto this mask plate while referring to the layout sheet above. , Paste this mask plate with the pasted original on the scanning drum of the scanner, input the input start point, use this input start point and the above layout information to determine the trimming range of the original, and use this trimming range to calculate the image data of the original. The present invention provides an automatic trimming layout method for printing plate making that takes in data, performs layout processing according to layout designation information given in advance, and stores the result in a memory.

〔Example〕

The present invention will now be described by way of example with reference to the accompanying drawings.

FIG. 1 shows an example of a configuration for carrying out the method of the present invention, in which 1 is a scanner and an original 2 is placed on its scanning drum.
Set and import um+II data.

A rotary encoder 3 is attached to the scanning drum. A linear encoder 4 for forming the axial position data of the scanning drum is associated with the scanning head 13 of the scanner l, so that the rotary encoder 3 and the linear encoder 4 can retrieve the scanning head position data on the scanning drum. It has become. This position data is given to the control device 5 together with the image data from the original.

In addition to this scanner, a memory 6, a data tablet 7, and a mask cutter 11 are connected to the control device 5. The image data extracted by the scanner 1 is stored in the memory 6. Further, a layout board 8 is set on the data tablet 7, and position data on the layout board is input using a cursor 9, and a magnification ratio is inputted using a numerical data input element in a menu area 10 and provided to the control device 5. Further, a mask original 12 is set in the mask cutter 11, and cutting is performed based on data from the control device 5 to create a mask.

Here, the signal that the control device 5 gives to the mask cutter 11 is:
It is formed based on layout information containing positional data and scaling factors input using the cursor 9 and numerical data input elements on the data tablet 7.

Next, the present invention implemented using the configuration shown in FIG. 1 will be described in detail.

First, the layout mount 8 is set at a predetermined position on the data tablet 7 at a predetermined angle. Then, the position data of a predetermined point on the layout board 8 is inputted to the control device 5 using the cursor 9 .

For example, when trimming a document into a rectangle, position data is input for two points, the upper left corner and the lower right corner of this rectangle. Thereafter, the magnification ratio is input using the numerical data input element in the menu area IO.

These input data are given to the control device 5 and stored, and after being subjected to arithmetic processing, are given to the mask cutter 11, which cuts the mask film set in the mask cutter 11 and cuts the trimming range inputted by the data tablet 7. Prepare a mask plate 12 with the cutout. At this time, multiple masks can be cut into one mask film.

Further, instead of the mask cutter 11, a plotter may be used to plot the trimming range on a transparent film plate to create a mask plate.

On this mask plate 12, a manuscript such as a photographic film is pasted while referring to the layout mount 8.
Create.

Image data is then captured by the scanner 1.

For this purpose, the mask plate 12 with the original pasted thereon is pasted on the scanning drum of the scanner 1. Needless to say, at this time, care should be taken regarding the direction of the mask plate 12.

In this state, the input starting point 8F is inputted using the rotary encoder 3 and linear encoder 4 provided in the scanner 1, as shown in FIG.

In the illustrated case, since the rimming range is rectangular, the input starting point is the upper left corner point. Once this input starting point 8F is determined, the trimming range of the document can be determined based on the input starting point SP and the layout information that has already been input to the data tablet 7 and has been processed by the control device t5. Furthermore, even when multiple manuscripts are pasted on a mask plate, if there is one input starting point SP for each mask plate, the relative positions of other manuscripts on the mask plate from the input starting point SP can be calculated. Therefore, the trimming range can be adjusted.

Then, the scanner l (2) scans the original 2 pasted on the mask plate 12 and captures image data only when scanning within the trimming range.This allows the image data of the trimmed original to be captured. can.

This image data is stored in the memory 6, and layout processing is performed in the control device 5 based on layout designation information and layout designation information previously stored in the memory 6 as well as the image data, and the geographical result is stored in the memory 6. By using the contents of the memory 6 in this state, automatic plate making can be performed.

[Effects of the Invention] As described above, the present invention sets the layout mount on the data tablet, inputs the layout position of the image and the position data of the trimming range, or further layout information including the magnification ratio, and calculates the layout tI? :Create a mask plate with the same input size as the original by cutting it out with a mask cutter or plotting it on a transparent film with a plotter based on step 4. Paste the original onto this mask plate and attach it to a scanner to find the input starting point. Since the input data is input, one image data is captured for each trimming range that is defined by the input start point and the layout information, and layout processing is performed. There are no problems such as the need for skill, and the layout can be easily trimmed.

That is, trimmed image data is written in the memory, and plate making can be easily performed based on this. Furthermore, since the original is pasted on the mask plate instead of the scanning drum, handling operations such as when exchanging the original from which image data is to be taken are significantly easier than when the original is pasted on the scanning drum.

By pasting the original onto this mask plate, on the one hand there is an advantage that there is no need to prepare multiple scanning drums, and on the other hand, there is the advantage that multiple originals can be pasted on one mask plate, which improves productivity. have
