Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scanner input preparation for preliminarily creating magnification, angle and trimming information when a color transparent original or a reflective original for platemaking is read and image data for printing is created. The present invention relates to a device and a print image data creation device.

[0002]

2. Description of the Related Art It is necessary to carry out printing plate making in accordance with the request of a client (client). Usually, this client draws the design image of the printed matter drawn in his head, that is, the layout information on the layout-designated paper in a freehand manner, and requests the printing on the layout-designated paper. Therefore, a gap is often inevitably formed between the finished printed matter and the design. As a result, the client often sees the printed product (generally, a proof-printed product) to make a design correction. In the end, the printing company cannot get the completion (without proofreading) only by the first school (first proof printing)
It is often necessary to make modifications by changing the design of the school and the client.

Further, a color original is submitted to the printing company together with the allocation designation. In the past, a printing company had to measure and determine color separation conditions such as magnification, angle, and trimming in order to perform color separation of an input manuscript, and the preparation process for color separation was troublesome. The scaling factor is the scaling factor for the finished size of the submitted manuscript.
The angle refers to the inclination angle of the document with respect to the horizontal and vertical lines of the finished page, and the trimming refers to the disassembly range of the document.

On the other hand, the client also determines the magnification, angle, and trimming when making the layout-designated paper, but nevertheless, the color separation of the measured magnification, etc. The actual situation is that the conditions are not reflected in the printing company as data for printing plate making. Therefore, both the client and the printing company performed the same work for the measurement of the magnification and the like.

The measurement of color separation conditions such as magnification, angle and trimming of a color original is generally performed by a magnification / angle / trimming measuring apparatus (hereinafter referred to as magnification measuring apparatus) using an optical system as shown in FIG. Is used. In this measuring apparatus, the color original is projected by the light source of the light projecting unit 10, and the designated allocation paper 12 is placed on the table 11. The upper and lower positions of the light projecting section 10 are adjusted so that the layout image and the projected image on the designated paper 12 are matched, and the image reading magnification is measured by the vertical position at this time.
Further, the original is rotated, the layout image and the projected image are aligned, and the angle is measured from the rotation angle. Also, the trimming range is measured by comparing the images.

In the above-mentioned magnification measuring device, if the light source is brightened, the measurement can be carried out accurately, but there is a limit to brightening the light source. It had to be done in a dark room. Such a dark room or a semi-dark room cannot be freely installed, and there are restrictions on the area and environment. Also, in the dark room,
Since it is a closed and dark space, it is not preferable in terms of working environment.

Further, since the magnification measuring device uses an optical system, it has a high magnification (for example, 2000% to
In order to perform measurement of 3000%), the size of the device itself must be increased, which makes development of the device difficult. That is, if the apparatus itself becomes large in this way, the dark room and the like must be naturally made large,
This is because the size and the environment are limited as described above, and thus the size cannot be freely increased.

[0008]

SUMMARY OF THE INVENTION Therefore, a technology that enables a client to create layout information that is not separated from printed matter, and a printing company uses the magnification, angle, and trimming information of a print document created by the client. There is a demand for a technique for obtaining the above and a technique for making it possible to measure the color separation conditions of the magnification, the angle, and the trimming of the printed document without using an optical system. There was a problem that no proposal was made.

When performing color separation based on the color separation data and layout data, a scanner preparation sheet (a sheet that indicates the position of the document to be read by the scanner with holes provided in the sheet) is created. The preparation of the scanner preparation sheet is a complicated work together with the layout paper preparation, but conventionally, there was no technique capable of eliminating this work.

The present invention has been made in view of the above-mentioned conventional problems. The client can create layout information that is not separated from the printed matter, and the magnification, angle, and trimming information of the print original measured by the client. To provide a scanner input preparation device that can be used by a printing company and can measure magnification, angle, and trimming without using an optical system.
And the subject.

A second object of the present invention is to provide a print image data creating apparatus which can create print image data without creating a scanner preparation sheet.

[0012]

According to the present invention, in a scanner input preparation device, means for creating image data of a print original at a resolution lower than that of plate-making data, and the created image data are displayed on a screen. Means for displaying,
A means for instructing a layout of created image data and color separation conditions such as image magnification, angle, and trimming with reference to an image on the screen, and processing the image data in accordance with the instructed layout and the color separation conditions. By providing a processing unit, a unit for displaying the processed image data on the screen, and a unit for outputting the layout and the color separation condition data determined based on the display image, the first It solves the problem.

Further, according to the present invention, in the print image data creating apparatus, the print image data is created from the image read from the print original based on the layout data and the color separation condition data output from the preparatory apparatus. Means are provided to solve the second problem.

[0014]

According to the present invention, in a scanner input preparation apparatus, image data of a print original is created at a resolution lower than that of print image data, the created image data is displayed on a screen monitor, and the displayed image is referred to. Then, the layout of each image and the color separation conditions such as magnification, angle, and trimming of each image are instructed. The instructed layout data and color separation condition data are output.

Therefore, the print requester can create the layout information while checking the image laid out in a state close to the finished state. Therefore, as compared with the conventional freehand designed layout paper, there is almost no separation from the printed matter. Therefore, it is almost unnecessary for the printing company to make a correction by changing the design of the client, and the plate making operation is extremely speeded up.

Further, if the color separation conditions are used in the printing company, the work of measuring the color separation conditions in the prior preparation for the printing and plate making becomes unnecessary, which also reduces the load of the plate making work and Efficiency and speed can be improved.

Since it is possible to determine the layout and the color separation condition while confirming the image data according to the specified layout and the color separation condition on the screen, a projection type optical system measuring device should be used. Without, the color separation condition can be determined. Therefore, since it is not necessary to prepare a dark room or a semi-dark room, it is possible to design without being restricted by the area and the environment, and the work environment is not deteriorated.

Further, since the color separation conditions can be measured without using an optical system measuring device, the necessity of enlarging the device itself at the time of performing high-magnification measurement is reduced, and problems in device development do not occur.

In the present invention, if the image is read from the print original and the print image data is created according to the output layout data and the color separation condition data, the layout and the color separation created by the client in the printing company. Regarding the conditions, the print image data can be created as it is without creating a so-called preparation sheet.
Therefore, the plate-making work is further speeded up.
