Thus, for example, when the user issues a print instruction for the original document of "document name: copy invisible", the client terminal 3 displays the file name of the print document of the user, that is, "document name". : Copy invisible "is recognized, and the correction value information (color:" ** color ", density:" cyan 10% "corresponding to the recognized file name (" document name: copy invisible ") is recognized. “Magenta 13%” “Yellow 14%”) and pattern information (pattern: “no enclosure” “angle 0 °” “position center”). Next, as a result of this search, the color or density and the pattern of the additional image to be added are corrected based on the detected color or density correction value information and the pattern information. After that, the additional image thus corrected is added to the image of the original document.

That is, according to such a configuration, the additional image (stamp) is automatically corrected according to the content of the file of the original document, so that if the additional image is designated, other designation is required. It is possible to instruct to print the additional image (stamp) without the need, and the usability for the user is improved.

Further, the present invention is not limited to the above-mentioned configuration, but rather than performing correction, an additional image in which each color, each density, and each pattern are determined in advance is stored in association with the above-mentioned file name. Then, the additional image corresponding to each user may be selected from them.

In this case, each file name is registered in advance in association with an additional image having a determined color, density or pattern.

When the user gives a print instruction, the file name of the user's print document is recognized, and an additional image having a color, density or pattern corresponding to the recognized file name is retrieved. To do. Next, as a result of this search, the detected additional image is added to the image of the original document.

That is, according to such a configuration, the additional image (stamp) is automatically added according to the content of the file of the original document, so that the usability is further improved.

Further, in the above-mentioned configuration, the file name such as the document name or the extension has been described as an example to be recognized as the content of the file, but the present invention is not limited to this, and is included in the document name of the original document. You may make it recognize also from the content of a character and the kind of image.

Further, the server 1 side, rather than the client terminal 3 side, is provided with a configuration for changing the color, density, or pattern of the additional image according to the above-mentioned login ID or file contents, so that the client terminal 3 can operate the server. It may be realized by instructing 1.

With the configuration described above, it is possible to realize a printing form as shown in FIG. 9 for preventing abuse of an illegally copied printed matter. That is, when an original document (a) printed with an additional image adjusted in color or density to be erased when copied is copied, the additional image portion is erased as shown in FIG. 9B. Since it is printed in the state, it is easy to see that it is not a legitimate original document.

That is, a predesigned certified logo mark or the like is printed in a color or density that disappears when it is copied in color or black and white, and the document with the certified logo mark is specified as the original document. By identifying what has disappeared as an illegal copy document,
It is possible to recognize at a glance that the original document is illegally copied by copying it with a copying machine or the like.
