Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a method for printing color documents created in an information processing device such as a document creation device, and particularly relates to a color document printing method suitable for color printing. It is something.

[Conventional technology]

When trying to print a color document created and displayed on a display, the image color is a transparent color.

It is difficult to exactly match printed colors due to reflected light. However, with NEC's PC-PR406-12 (color copyboard), the hardware is configured to create a one-to-one correspondence between image colors and print colors, which is generally considered to be the closest approximation. Therefore, high-speed color conversion is performed. However, since the correspondence is approximate, documents may not be printed in the colors desired by all five users.

[Problem that the invention seeks to solve]

The above-mentioned prior art may also cause an intolerable mismatch between the colors of the video display document and the colors of the printed document for the user.

An object of the present invention is to enable the user to easily establish a correspondence between image colors and print colors.

The aim is to make printed documents more similar to the documents desired by users.

[Means for solving problems]

The above purpose is to provide a rewritable color correspondence table between video colors and print colors that are referenced when printing documents consisting of characters, figures, etc., and to display the video displayable colors and printable colors on the display. Furthermore, after displaying the correspondence data of an existing color correspondence table on the display L/I, this can be achieved by changing the correspondence of the color correspondence table using the input device.

[Effect]

When printing, the document is printed by converting the image colors into print colors using the color correspondence table specified by the user, so the user can print a color document with the colors desired.

Furthermore, by controlling the color correspondence table described above so as not to print the image colors, it is also possible to print only a portion of the document.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram illustrating an embodiment of the present invention, in which 1 is an input device, 2 is a processing section, 3 is a display for displaying documents, etc., and 4 is a printing device 12, which is a memory.

The processing section is mainly composed of three control sections, namely, a display control section 7, a color correspondence table rewriting control section 5, and a printing control section 8.

First, document data 9 input from the input device 1 is stored in the memory 12 and sent to the video display control section 7.

The video display control section 7 converts the color data of the document data 9 into video color data using the lookup table 10, and displays the document on the display 3 in the video color. In the color correspondence table rewriting control section 5, the color correspondence table 1
Read the data of 1 and select the colors that can be displayed in the image, the colors that can be printed,
In order to display an outline of the contents of the table data on the display 3, data for this purpose is sent to the video display control section 7.

Further, the user writes the newly associated relationship between the video color and the print color into the color correspondence table 11 via the input device 1. Finally, the print control unit 8 reads one document data 9, converts the color data into image color data using a lookup table 10, further converts the image color data into print color data using a color correspondence table 11, and prints the The color data and document data 9 are sent to the printing device 4 to control printing.

It goes without saying that during this printing, the image color data may be converted when the document is displayed for the first time, and the image color data stored may be used to directly convert the image color data into print color data.

Next, as a specific example, R (red), G (green), B (blue)
8 colors based on 5 colors (red, green, blue, yellow [R+
Displays 3 and Y that can display images (G], magenta [R+B], cyan [B+G], white [R+c+B], black)
(yellow)% M (magenta), C (cyan) 8 colors (yellow, magenta, cyan, purple [M
+C]・Green [y+c:l・Red [Y1M]・Black [y+u+
A method of printing a color document containing characters and graphics displayed on the display 3 using the printing device 4 capable of printing white [paper color (control not to print)] will be described. Before explaining this processing operation, the structure of the color correspondence table stored in the memory 12 used in the present invention used for this processing operation will first be explained.

FIG. 2 is a table showing the correspondence between displayable colors on the display 3 and printable colors on the printing device 4.

By rewriting 50 to 37 in this color correspondence table, it is possible to change the subcolor of the mark when printing the display color.

Now, the processing operation in this embodiment will be explained using FIG. 3. FIG. 5 is a flowchart showing processing operations in one embodiment of the present invention.

The process begins at block 40. First, data in the color correspondence table 11 is read out according to the user's instructions (block 41), and the correspondence is displayed on the display 5 (block 42). 4 and 5 are examples of the correspondence displayed on the display 3.

In FIG. 4, 50 is a display field for the image display color;
59, eight displayable colors are displayed.・5
1 is a printing color display column, and 60 to 67 display eight printable colors. Each of these eight colors may be associated with a display color to a print color using an input device, and then displayed by connecting them with a line as shown in 68. (Block 43). Also,
In FIG. 5, 282 to 89 are display columns for image display colors;
Each can display eight displayable colors. 80 is the print color display field, and %98 to 105 display the printable colors. The user may select the video color to be printed using the input device and display it with a mark like 92, or other display methods may be used. In both Figures 4 and 5, a one-nil correspondence is created from the image color to the print color. Further, since the display of printed colors is inaccurate when displayed by video, a removable printed color sticker may be pasted on the display.

The printed color stickers are printable colors printed on paper, and by pasting them on the 8 printable color fields on the display using a suction plate or similar material, the actual printed colors can be shown. Be able to make a correspondence.

The color correspondence table 11 shows the color correspondence changed by the user according to the display display as described above.
is rewritten by the function of the color correspondence table replacement control unit 5 (block 44). In FIG. 2, image color A. For example, the printing color corresponding to ``Bo'' is changed to ``B''. In block 45, it is determined whether to continue or terminate the rewriting of the color correspondence table 11 based on input data from the input device 1 input by the user. At block 46, rewriting of the color correspondence table 11 is completed. When printing a color document, the print control unit 8 converts the color data of the document data 9 into print color data corresponding to the display display color using the color correspondence table 11, and uses the converted data to print the color data in the printing device. and print it.

By applying the embodiments described above, it is also possible to print any part of a document. A case in which printing is performed according to the correspondence shown in FIG. 5 will be described. 98-105
are the printing colors, white (paper color), cyan, magenta, purple, yellow, green, red, and black, respectively. (The printed color stickers are yellow.) 90 to 97 and 106 to 115 display image colors, black, blue, green, cyan, red, purple, yellow, and white.

If the user associates colors as shown in FIG. 5, the color correspondence table in FIG. 2 will become as follows.

Ao-A corresponds to the video colors shown in 90 to 97 as they are with symbols, and B0 to B correspond to 9 with a "V" mark.
Corresponding to 0-97, 106-115, Bo・B,・
B.

・B, ・B are assigned symbols corresponding to white printing color, and other symbols corresponding to black printing color. When printing is performed according to this r-pull, only the figures and characters drawn in green, red 2, or white on display 3 are printed in black, and the figures and characters drawn in other colors are printed in black. Figures and characters are not printed. In this way, it is possible to print parts of a document.

Although the two embodiments have been described above, it goes without saying that by combining these two embodiments, partial color printing of a document becomes possible.

〔Effect of the invention〕

According to the present invention, when printing a color document, it is possible to easily change the correspondence between the image color and the print color of the document, so that it is possible to print a color document that satisfies the user.

Also, when printing, there is a color simulator for printing colors! 1 is,
Another advantage is that it can be done easily without changing the color data of the document one by one. Furthermore, it is also possible to partially print a document that has been color-coded in advance according to the purpose.
