A table editing unit 29, a conversion table storage unit 30, and a document data storage unit 31 are provided.

  The copy-forgery-inhibited pattern setting storage unit 21, the conversion table storage unit 30, and the document data storage unit 31 are configured using, for example, an HDD, and the user notification unit 28 is configured using a display unit. The storage determination unit 23, the copy-forgery-inhibited pattern setting conversion unit 24, the copy-forgery-inhibited pattern image generation unit 25, the synthesis unit 26, the locale acquisition unit 27, and the conversion table editing unit 29 are a program stored in a ROM, RAM, or HDD, or an ASIC (Application Specific IC). ) Or the like. The conversion table may be incorporated in the program.

  The background pattern setting storage unit 21 stores background pattern setting information such as the content, type, size, and color of the background pattern image. The copy-forgery-inhibited pattern setting information is taken into the client apparatus 2 via a recording medium such as a memory card or a CD-ROM, or a network such as a LAN or the Internet, and is stored in the copy-forgery-inhibited pattern setting storage unit 21. It may be created.

  The background pattern setting acquisition unit 22 acquires the background pattern setting information from the background pattern setting storage unit 21, and the locale acquisition unit 27 acquires the locale (environment locale) of the client device 2.

  The locale storage determination unit 23 determines whether the locale obtained from the background pattern setting information acquired by the background pattern setting acquisition unit 22 and the locale of the client device 2 acquired by the locale acquisition unit 27 are the same.

  The copy-forgery-inhibited pattern setting conversion unit 24 conforms to the locale of the client apparatus 2 with reference to the conversion table stored in the conversion table storage unit 30 when the locale storage determination unit 23 determines that the locale is dependent (the locale is different). The background pattern setting information is converted as described above.

  The copy-forgery-inhibited pattern image generation unit 25 generates a copy-forgery-inhibited pattern image formed of a bitmap based on the copy-forgery-inhibited pattern setting information converted by the copy-forgery-inhibited pattern setting conversion unit 24 or the copy-forgery-inhibited pattern setting information before conversion. The copy-forgery-inhibited pattern image is not limited to a bitmap.

  The composition unit 26 superimposes the copy-forgery-inhibited pattern image generated by the copy-forgery-inhibited pattern image generation unit 25 on the document data read from the document data storage unit 31.

  The document data storage unit 31 stores document data created by word processing software in the client device 2 and converted into PDL data by the printer driver. The document data may be captured via a storage medium such as a memory card or CD-ROM, or a network such as a LAN or the Internet.

  The user notification unit 28 notifies the user using the display unit of the PC or the like when the locale setting determination unit 23 does not match the locale of the tint block setting and the locale of the client device 2. Note that the user may be able to select whether or not to execute the tint block setting conversion using the input unit of the PC or the like.

  The conversion table editing unit 29 edits the conversion table stored in the conversion table storage unit 30 based on an input operation from the input unit by the user, so that the setting can be registered, deleted, and changed by the user. It is configured.

  FIG. 3 shows an example of a tint block image generated by the tint block image generation unit 25. 3A shows a copy-forgery-inhibited pattern image, and FIG. 3B shows a copy image obtained by copying the copy-forgery-inhibited pattern image 32 in FIG. 3A with a normal copying machine (printer). The copy-forgery-inhibited pattern image 32 shown in FIG. 3A is a binary monochrome image with 1 bit per pixel, and includes a background pattern 35 and hidden characters 33. The character “COPY” in FIG. 3A is an example of the hidden character 33 and is superimposed on a dot-like background pattern 35 (shown by hatching in FIG. 3A). Since the hidden characters 33 are actually set to the same density as the background pattern 35, they are not clearly visible as shown in FIG. 3A, but are drawn for easy understanding. FIG. 3C is an enlarged view of the portion 32a surrounded by the square frame of the hidden character 33. The white rectangle and the black rectangle represent a white pixel and a black pixel, respectively.

  As shown in FIG. 3C, the hidden characters 33 have relatively large dot patterns arranged relatively coarsely, and the background pattern 35 has relatively small dot patterns arranged relatively densely. The hidden characters 33 and the background pattern 35 are provided so that the average density (black pixel area per unit area) when printed on paper is the same. Accordingly, the human eyes cannot distinguish between the hidden character 33 and the background pattern 35, and the entire surface appears to be a uniform gray background.

  When print data obtained by combining the copy-forgery-inhibited pattern image 32 of FIG. 3A with document data is once printed by the printer 3 and the printed paper is copied by another general-purpose copying machine or the like, the hidden character 33 having large dots is faithfully displayed. However, the background pattern 35 with small dots is not reproduced faithfully. Therefore, the area of the background pattern 35 is white, so that a copy image 34 as shown in FIG. 3B in which a hidden character 33 appears on the document image is obtained. Thereby, unauthorized copying can be suppressed. Note that what is actually printed on the sheet is an image obtained by synthesizing the document image from the document data storage unit 31 with the copy-forgery-inhibited pattern image 32 of FIG. 3A by the synthesizing unit 26, but in FIG. For ease of explanation, the document image is not shown.

  FIG. 4 shows another example of the background pattern used for the tint block image. In FIG. 3, a dot pattern is used as the background pattern 35. However, as shown in FIGS. 4A and 4B, a background pattern 35 having a diagonal pattern can be used. The background pattern 35 in FIGS. 4A and 4B can represent digital data such that one is “0” and the other is “1”, and these are used to prohibit copying. Etc. can be embedded to control the printer 3.

(Operation of image processing system)
Next, the operation of the image processing system 1 will be described with reference to the flowchart of FIG.

  First, the user operates the input unit of the client device 2 to set attribute information to be added to document data to be printed. The attributes input here include document data specification information to be printed, information for controlling document data copy, background pattern type to be superimposed (background pattern information), hidden character string, font, font size, There are character decoration, character string angle, hidden character superimposition position, hidden character information such as width, height and color.

  Next, when the user operates the input unit to instruct generation of print data, the CPU of the client apparatus 2 will explain print data generation control according to the print data generation program stored in the ROM as described below. Do.

  The locale acquisition unit 27 acquires the locale of the client device 2 such as the language and region from the current setting information (S101). Further, the background pattern setting acquisition unit 22 acquires the locale of the background pattern setting from the background pattern setting information stored in the background pattern setting storage unit 21 (S102).

  Next, the locale preservation | save determination part 23 compares the locale of the client apparatus 2, and the local locale of a tint block setting, and judges whether both are in agreement (S103). For example, if the hidden character 33 of the background pattern setting information is in Japanese and the locale of the client apparatus 2 is also in Japanese, it is determined that the locales match (Yes), and one is in Japanese and the other is in English Determines that the locales do not match (No).

  If the locales match (S103: Yes), the background pattern image generation unit 25 generates a background pattern image from the background pattern setting information stored in the background pattern setting storage unit 21 (S104).

  If the locales do not match (when there is locale dependency) (S103: NO), the user notification unit 28 notifies the user to that effect (S105), and determines whether to convert the tint block setting information to the user. Select (S106). When there is a change instruction (S106: YES), the background pattern setting conversion unit 24 refers to the conversion table stored in the conversion table storage unit 30 to convert the language of the background pattern setting information into the language of the client device 2 and newly The background pattern setting information is generated (S107).

  When the user does not instruct the change in step S106 (S106: NO), the background pattern generation unit 25 generates a background pattern image from the background pattern setting information acquired by the background pattern setting acquisition unit 22 (S104).

  The composition unit 26 converts the copy-forgery-inhibited pattern image generated by the copy-forgery-inhibited pattern image generation unit 25 into PDL data, superimposes (combines) the PDL document data read from the document data storage unit 31 with the synthesized image, and Print data is output to the printer 3 via an interface (not shown) in the client apparatus 2 and the NW 4.

  The printer 3 converts the PDL print data from the combining unit 26 into bitmap data and prints it on a designated sheet. The image on the printing paper is a composite of a copy-forgery-inhibited pattern image composed of hidden characters and a background pattern and document data.

(Effects of the first embodiment)
According to the first embodiment, the following effects are obtained.
(A) Even when the locale of the background pattern setting information is different from the locale of the client device 2 that interprets the background pattern setting information, the original purpose of the background pattern image can be achieved and unauthorized copying can be suppressed.
(B) Even when printing is performed in a locale not intended by the document creator, the illegal copy suppression pattern is printed. Therefore, it is possible to suppress unauthorized copying regardless of the printing environment.

  In step S103, if the locales do not match (S103: NO), the background pattern setting information may be converted without allowing the user to select whether to convert the background pattern setting information. The user's operation can be saved.

  After step S105, the conversion table editing unit 29 edits the conversion table stored in the conversion table storage unit 30 based on the input operation from the input unit by the user, and the background pattern setting conversion unit 24 performs the editing. The tint block setting information may be changed based on the conversion table. Thereby, even if there is a character string that does not exist in the conversion table, it can be dealt with.

  Also, what if the background pattern setting language is not in the conversion table? The copy-forgery-inhibited pattern image may be generated by converting it into a specific character such as a character or a Δ symbol. For example, when the background pattern setting language is Chinese in the conversion table between Japanese and English, the hidden character is converted into a specific Japanese character. Thereby, garbled characters can be avoided, and a specific character can perform the function of a hidden character.
