2. Description of the Related Art Conventionally, a general map, for example, a map in which a target subject is displayed on a topographic map of a scale of 1: 200,000 / 50,000 or 1: 25,000 published by the Geospatial Information Authority of Japan, That is, a theme map is created. Such a thematic map firstly takes a commercially available topographic map, for example, a topographic map published by the Geographical Survey Institute, creates a base plate film, prints this base plate film on diazo, and creates an original drawing for tracing. create.

In the line drawing of the theme map, the original drawing prepared as described above is arranged on the manuscript of the theme map, and the boundary line shown in the manuscript of the theme map is set against the background of the manuscript of the theme map. Alternatively, it is produced by tracing on the original drawing with a pen or the like. For the purpose of color printing, a line plate is prepared for each color unit so as to facilitate color plate making. In this case, a film that can be inked, that is, a mylar is prepared for each color unit, and a traced line is drawn with a pen or the like using black, for example, for each mylar for each color unit.

[0004] Writing of characters on the original drawing is performed by a note plate. The annotation plate is made by photo-typesetting on a different Mylar from the line plate, and the characters are entered on the original drawing by attaching the annotation film to the line plate. Annotation plates are made in color units, similar to line plates. The stencil plate and the note plate are combined to create an indigo ware, which is then inspected and corrected against the manuscript of the theme map.

[0005] In order to add colors to the theme map, a color separation model is prepared for each color of the original of the theme map, and a mask plate is formed by line printing. When a mask plate is formed using a peel coat with a light-shielding thin film that is easily adhered to a relatively thick transparent film, a linear plate positive film for each color unit is converted to a negative film. Flip,
Negative films for each color unit of the obtained line plate are placed on the peel coat for each corresponding color unit, and baked by daylight photographic processing for each corresponding color unit, and the light-shielding properties of the daylight peel coat are Form a cut in a thin film, peel off the light-shielding film of the part that needs coloring,
Make a mask plate.

[0006] The positive films of the line plate and the note plate are inverted to a negative film, and the pinholes of the negative film are filled with a light-shielding paint so as to prevent contamination, thereby producing an aluminum print. In producing an aluminum printing plate, a line plate, a note plate, and a mask plate of each density unit for each color are printed by register multiple printing. Next, a proof print of the same finish as the printing is created and proofread. Correction is made according to the correction of the line plate and the note plate and the change of the color, and the process from reversal of the positive film to the negative film to proof printing is repeated. After the proofreading is completed, it is printed and commercialized.

[0007]

However, according to the conventional handwriting method, when producing a theme for color printing,
The production of many line plates, note plates, mask plates, and the like for each color unit requires many fine manual operations, and requires a lot of labor, resulting in an increase in manufacturing cost and a problem. In addition, the number of line plates, note plates and mask plates also increases, and it takes a lot of space to store those plates. Has been considered as a problem.

Further, according to the conventional method of making a mask by performing raster conversion by reading an original figure copied by handwriting with a scanner, the size of the file becomes enormous as the size to be printed becomes large, making the copying operation difficult. It is. In addition, the data may be recreated depending on the change of the boundaries and colors of the theme map. However, each time the work must be started from the beginning, it takes a lot of time and is a problem. Furthermore, since it is used in combination with a copy of a manuscript of a theme map created by conventional manual drafting or a film of a base plate, there is often a problem of lack of consistency with the theme.

However, even in this method, the manuscript of the theme map is copied by hand, and a line plate for each color is created.
Each of the linear units for each color unit is read by a scanner, raster data is created, the raster data is vector-converted, and each color unit is converted based on a separation model created based on the manuscript of the theme map. A color separation model is prepared on the basis of the vector data of the linear plate, and a mask plate is prepared by adding a legend color and outputting the film.

Therefore, in another method, a manuscript of a theme map is copied by hand, and a line plate is prepared for each color. The line plate and the base plate are input by a scanner to prepare raster data. This raster data is normalized, converted into vector data, and edited. After checking the consistency between the base plate and the line plate , the mask plate is prepared by inputting attributes such as line number, line type, and designated color.

However, since the work process proceeds by handwriting, the advantages of digital drafting cannot be utilized, and various restrictions are imposed by handwriting work, which still requires a lot of trouble, and requires a mask plate for each color unit. It must be preserved, which is a problem. When digitizing the above thematic maps, it is necessary to copy them by hand, and then read each of the copied figures with a scanner to produce digital data. It is. In addition, it takes a long time to obtain consistency between the transcribed drawing of the manuscript of the theme map and the base plate version, which poses a problem. SUMMARY OF THE INVENTION An object of the present invention is to solve many problems relating to manual work and problems relating to film preservation in the production of a theme map by a conventional method.

It is also easy to make the width of a line relatively thin and relatively wide. Therefore, in the present invention, for example, even if a vector is input with a low-resolution thick line, it is easy to print as a high-resolution thin line. It is.

In the present invention, the thematic map manuscript and the base map are respectively scanned by a scanner connected to a computer.
The digitized digital data of the thematic map manuscript and the digital data of the base map are digitally processed, respectively, and displayed on a display connected to a computer. The same digitized theme map document image is superimposed on the digitized base map image displayed on the display screen, and a digital code portion for displaying a white background portion of the digitized theme map document image is made transparent. The processing is performed so that the base draft manuscript located below the subject map manuscript image can be seen on the display. When the base draft located below the subject map draft image is made visible in this way, the reference topography of the base draft is confirmed, and the topographic image is distorted due to the expansion or contraction of the paper surface or film, and the image is displaced by deformation. Is preferred because it is possible to reduce When an integrated image of the subject map manuscript image and the base image is created, the integrated image includes
Since the terrain image appearing in the thematic map manuscript and the reference terrain image appearing in the base map are displayed at the same time, it is preferable to display one of the colors differently from the other. In this case, since the terrain of the base map is represented in black, the terrain of the base map is displayed in gray scale or the like, and the terrain and the visual image of the theme map document can be seen at a glance in red and other noticeable differences. It is preferable to express colors.

Many of the thematic maps are made in multicolor printing,
On the base plate for printing, a register mark, such as a register mark, is attached to a registering position. In order to do so, the integrated image is registered with a high-resolution base image of a base plate, and a subject image such as a boundary line shown in a thematic map original image appearing in the integrated image is tracked by, for example, a cursor. Then, an image of a subject such as a boundary line is input as a vector to create vector data. The vector data obtained in this way is
At the time of printing, vector data of a subject image such as a boundary line is converted into raster data, subjected to color separation and separation in accordance with multicolor printing, and output to a film for producing a corresponding color plate. In the present invention, in addition to the base plate, a number of color plate films corresponding to the multicolor printing are prepared, and the theme map is based on the base plate raster data and the raster data of the subject image such as each boundary line.

It is stored in the digital data storage as a file for the base plate film output. The digital image of the thematic map manuscript has a low resolution, e.g., 200 dpi, so that lines such as field lines in the thematic map can be easily tracked with a cursor.
The image is displayed on a display and checked, and then stored in a digital data storage different from the base version digital data storage. The digital image of the file created in this manner can be subjected to image processing as it is. For example, conversion to encapsulated PostScript format page description data facilitates subsequent image processing. preferable.

According to the present invention, the manuscript of the theme map includes a topographic map portion and visual information serving as the theme of the theme map. In the present invention, the visual information is point data, line data, surface data, and text data, which are so-called vector data. Among them, the point data is, for example, a government office, a shrine, a temple, a school, a police station, a police station, And a display such as a building such as a hospital, a boring position in a geological map, a hot spring and a quarry, and the like. It is a position of an active fault line or the like in a diagram or the like, and surface data is, for example, a boundary line of various theme maps, for example, a geological boundary,
It is the location of boundaries such as topography, vegetation, and soil, and the location of lines such as commercial, industrial, and agricultural land in land use maps, and the text data consists of letters indicating the names of roads, railways, government, and buildings. Shape. In the present invention, since the manuscript illustration of the theme map and the base version must overlap, the file of the digital image of the manuscript of the theme map and the file of the digital image of the base map are processed by a computer.
Normalized to the same size. By normalizing this file, it is possible to avoid the disorder in the figure due to the inclination of the image or the expansion and contraction of the paper at the time of inputting by the scanner. In the present invention, in order not to increase the data size of the digital image, the digital image of the base plate can be digital data of a monochrome binary image.

In producing the integrated image, the digital image of the base plate is converted to gray scale, and is assigned to one of a plurality of layers. The digital image of the original plate of the thematic map is converted into data in the RGB color mode. Is converted to the above layer, assigned to the layer above the layer, superimposed, and the digital code of the RGB color mode indicating the white color of the image of the upper layer is deleted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
It is not limited at all. FIG. 1 is a block diagram mainly showing a computer of a subject map producing apparatus used in a subject diagram producing process according to an embodiment of the present invention. FIG. 2 is a flowchart showing a process for producing a theme drawing according to an embodiment of the present invention. FIG. 3 is a diagram showing a file hierarchical structure of each layer in an allocation step of a production step of the theme diagram of the embodiment shown in FIG. FIG. 4 is a diagram showing the file hierarchical structure of each layer in the vector editing step of the production step of the theme diagram of the embodiment shown in FIG. 1 to 4, corresponding parts are denoted by the same reference numerals.

In one embodiment of the present invention shown in FIGS. 1 to 3, a central processing unit (CPU) 1 of a computer is connected to an input / output device 4 through an input line 2 and an output line 3 so as to be able to input and output. Also, the input line 5 and the output line 6 are connected to the display device 7 so as to be able to input and output,
Further, the input line 8 and the output line 9 are connected to the digital scanner 10 so as to be able to input and output, and the input line 11 and the output line 12 are connected to the data storage device 13 so as to be able to input and output. The central processing unit 1 of the computer
And by an output line 15, and input and output connected to the printer 16, also the input line 17 and output line 18, and input and output connected to the raster image processor 19, or even, raster image processor 19, an output A line 20 is connected to a film output device 21 so as to be able to output.

The input / output device 4 converts the base diagram 22 into a high-resolution monochrome binary digital data file 24 of the base diagram in a 400 dpi high-resolution scanning step 23 using the digital scanner 10. The high-resolution image digital data file 24 is normalized in a normalization step 25 by the digital scanner 10 to produce a high-resolution image digital data file 26 for a normalized film output file. Stored in the first storage unit. In this example, the digital data 26 of the normalized high-resolution image shown in the base diagram 22 can be produced with 256 gray levels, but the background of the figure is colored and the data size is small. Monochrome binary is adopted because it becomes large.

The high resolution normalized digital data file 26 for the base plate is instructed by the input / output device 4 and converted by the digital scanner 10 into a conversion step 27.
Then, the normalization of the digital data file 26 of the normalized high-resolution base image is fixed as it is, converted to the RGB mode, and the digital data file 28 of the high-resolution image converted to the RGB mode is obtained. Is stored in the second storage unit of the data storage device 13. Further, the digital data file 24 of the high-resolution image of the base map is instructed by the input / output device 4 to be used as a background image, and is converted into a normalized high-resolution image in the conversion step 27 by the digital scanner 10. The normalization of the digital image file 26 of the base image is fixed and grayscaled, and the digital data file 29 of the grayscaled high-resolution image is fixed with the normalization unchanged. The image is sent to the resolution reducing step 30 by the scanner 10 to reduce the resolution to 200 dpi. The digital data file 31 of the low-resolution image of the gray scale base map is stored and held in the third storage unit of the data storage device 13.
