The external storage device 93 is provided with a storage area for storing the print job transferred from the RAM 92, a storage area for storing the color table, and a storage area for storing the display method table.

FIG. 2 is a diagram showing an example of a color table stored in the external storage device 93.

The color table associates the predetermined color ranges D111a to D111d of the original document with the universal design colors D112a to D112d, and stores the color names D110 and the RGB values S120, respectively.

Here, in consideration of the variety of color vision, "Color Universal Design" is to convert colors that are difficult to recognize (color combinations) into visually recognizable colors (color combinations) for many color-impaired people. The color selected based on Color Universal Design shall be referred to as "Universal Design Color" in the present specification.

In the example shown in FIG. 2, for example, in D111a in which the color name D110 is "dark red of the original document", the RGB values D120 are R values: 128 to 255, G values: 0 to 75, and B values: 0 to. It is defined as 65.

The RGB value D120 of D112 whose color name D110 is "universal design color orange" is defined as R value: 255, G value: 153, and B value: 0.

That is, in the dark red of the original document in which the RGB value D120 is R value: 128 to 255, G value: 0 to 75, and B value: 0 to 65, the RGB value D120 is R value: 128 to 255 and G value: 0. It shows that the color can be converted to the universal design color orange having a B value of ~ 75 and a B value: 0 to 65.

FIG. 3 is a diagram showing an example of a display method table stored in the external storage device 93. In the display method table, rules are stipulated regarding the display method of the mark.

As shown in FIG. 3, the display method table has a character orientation D210 indicating the direction of the character data to which the mark is added, a description position D220 indicating the description position of the mark, and whether or not the character data is continuous. The continuous presence / absence description position D230 indicating the position and the registered color name description D240 indicating the name of the converted universal design color are stored in association with each other.

Here, the round point D211 and the arrow D212 are stored as marks.

The circle dot D211 indicates that the character data is used when the character data is not continuous because the same color character continuity at the continuous presence / absence description position D230 is set to "none" and the individual color characters are set to "individual". ..

The arrow D212 is used when the character data of the same color character at the continuous presence / absence description position D230 is set to "one place each at the beginning and the end" and the individual color characters are set to "none". It is shown that.

Returning to FIG. 1, the CPU 90 has a color conversion means 95, a character continuation determination means 96, and an addition means 97 in terms of its function.

The color conversion means 95 determines whether or not the color of the character data included in the color image data is within the color range based on the color table stored in the external storage device 93. Specifically, the color conversion means 95 determines whether or not the color of the character data is included in the RGB values D120 of the predetermined color ranges D111a to D111d of the original document of the color table. Then, when it is determined that the color of the character data included in the color image data is within the color range, the color conversion means 95 converts the color into a universal design color corresponding to the color of the character data.

For example, when the RGB value D120 of the character data of the original document is R value: 250, G value: 241 and B value: 0, the RGB value D120 corresponds to the predetermined color range D111b of the original document. The color is converted to the universal design color yellow, which is 250, G value: 245, and B value: 0.

The character continuation determination means 96 determines whether or not the character data of the same color converted by the color conversion means 95 is continuous. For example, when the characters "A", "B", "C", and "D" that have been color-converted to the universal design color orange are continuous in horizontal writing, the character continuous determination means 96 has continuous character data of the same color. Judge that it is.

The addition means 97 adds a universal design color mark to the character data converted by the color conversion means 95 based on the display method table stored in the external storage device 93. At this time, the addition means 97 may add marks to the beginning and end of the character data determined to be continuous by the character continuation determination means 96.

FIG. 4 is a flowchart showing a processing procedure in the inkjet recording apparatus 1 of the printer network system of the present embodiment.

As shown in FIG. 4, when the scanner unit 101 reads the original data (color image data) (step S101; YES), in step S103, the read color image data is written vertically or horizontally based on the user's specification. Set.

In step S105, the color conversion means 95 determines whether or not the read color image data includes character data other than black (step S105).

When only black character data is included (step S105; NO), there is no need for color conversion, so the process proceeds to step S127 as it is.

On the other hand, when character data other than black is included (step S105; YES), the color conversion means 95 changes the color of the character data included in the color image data based on the color table stored in the external storage device 93. It is determined whether or not it is within the color range (step S107).

When it is determined that the color of the character data is within the color range (step S107; YES), the color conversion means 95 converts the color into the universal design color corresponding to the color of the character data (step S109).

In step S111, the character continuation determination means 96 determines whether or not the character data of the same color converted by the color conversion means 95 is continuous in the same column or in the same row.

When it is determined that neither the same column nor the same row of character data of the same color is continuous (step S111; NO), it means that only one non-consecutive character is color-converted.

Therefore, in step S113, the addition means 97 adds a circle point on or beside the character data as a mark based on the display method table stored in the external storage device 93.

FIG. 5A is a diagram illustrating the addition of a mark when the character data of the same color converted by the color conversion means 95 is not continuous, and FIG. 5B is a diagram showing the same color converted by the color conversion means 95. It is a figure explaining the addition of the mark when the character data of is continuous.

The character data G110 shown in FIG. 5A indicates the character “A” written horizontally. In the example shown in FIG. 3, at the round point D211 the horizontal writing position D220 is "upper". Therefore, as shown in FIG. 5A, when the character data is written horizontally, the addition means 97 adds a round point G111 on the upper side of the character data G110 of the horizontal writing "A".

Further, the character data G120 shown in FIG. 5A shows the character “A” written vertically. In the example shown in FIG. 3, at the round point D221, the vertical writing position D220 is “right”. Therefore, as shown in FIG. 5A, when the character data is written vertically, the addition means 97 adds a round dot G121 to the right side of the character data G120 of the vertical writing "A". This makes it clear which character data has been color-converted. The circle dots G111 and G121 are described in the same color as the modified universal design color, as shown in the upper left of FIG.

Returning to FIG. 4, when it is determined in step S111 that the character data of the same color are continuous in the same column or in the same row (YES), the entire continuous character string is color-converted.

Therefore, in step S121, in the case of vertical writing, the additional means 97 specifies the character at the top (start) of the same column and the character at the bottom (end) of the continuous character data, and writes horizontally. In the case of, the leading character (starting) of the same line is specified and the last (ending) character is specified from the continuous character data (step S121).

In step S123, the additional means 97 uses characters as marks at the beginning and end of the character data determined to be continuous by the character continuation determination means 96 based on the display method table stored in the external storage device 93. Add an arrow to point inside the row.

The character data G210 shown in FIG. 5B shows the character strings G210a to G210d of the horizontally written "ABCD". In the example shown in FIG. 3, in the arrow D212, the horizontal writing position D220 is “up”. Therefore, as shown in FIG. 5B, when the character data is written horizontally, the addition means 97 puts a character string on the G210a indicating the first "A" in the character data G210 of the horizontally written "ABCD". The arrow G211a is added so as to face the inside (here, the right side) of.

Further, the addition means 97 adds an arrow G211b so as to face the inside of the character string (here, the left side) on G210d indicating the end "D" in the character data G210 of the horizontally written "ABCD". ..

The character data G220 shown in FIG. 5B shows the character strings G220a to G220d of the vertically written "ABCD". In the example shown in FIG. 3, in the arrow D212, the vertical writing position D220 is “right”. Therefore, as shown in FIG. 5B, when the character data is written vertically, the addition means 97 is on the right side of the character data G220 of the vertically written "ABCD", which indicates the leading "A", on the right side. The arrow G221a is added so as to face the inside of the character string (here, the lower side).

Further, the addition means 97 adds an arrow G221b to the right side of the character data G220 of the vertically written "ABCD" indicating the last "D" so as to face the inside (here, the upper side) of the character string. do. The arrows G211a, 211b, 221a, and 221b are described in the same color as the modified universal design color, as shown in the upper left of FIG.

Next, the addition means 97 adds a registered color name (step S125). For example, the addition means 97 describes the color name of the color-converted universal design color on a part of the paper.

In step S127, the CPU 90 controls the printer unit 102 to print based on the color-converted color image data.

Further, in the inkjet recording device 1 according to the embodiment of the present invention, an inkjet line color printer that prints in line units has been described as an example, but the present invention is not limited to this, and is a serial type inkjet recording device. You may. That is, any printing device that prints on paper based on color image data may be used.
