[0002]

2. Description of the Related Art In recent years, printing equipment has been remarkably developed, and full-color printing for reproducing various colors has been frequently used by general users. For example, when it is desired to print in the same color as a printed image such as a poster on a street corner, first, the printed image is scanned with a scanner or the like to obtain image data as a scanned image. Next, so that the image data is reproduced by the image forming apparatus,
The image data is converted into print data using the conversion data unique to the image forming apparatus. A print that reproduces a poster is printed by the image forming apparatus using the obtained print data.

[0003] With the spread of the Internet, various print systems using the Internet have been considered. For example, JP-A-2000-31
In the Internet print system described in Japanese Patent No. 6672, a printing device such as a copying machine or a printer obtains an HTML document on the Internet and a control driver of the printing device and prints them. Also, JP-A-11-1
According to the information processing method described in Japanese Patent No. 10393, a URL address is acquired from a facsimile document, and the URL
The original document is acquired by accessing the L address, and the document is transmitted to a predetermined destination. Further, in the information processing system described in JP-A-11-312064, a data icon and a print designation printer icon are embedded in an HTML document, and a printer attribute is acquired by dragging and dropping the data icon and the printer icon. To generate appropriate print data.

Image data of an image and correction data for correcting conversion data used for converting the image data into print data are obtained, and print data is obtained using the image data and the correction data. Further, a reproduced image for reproducing the printed image is printed by the printer unit using the print data. Since the image data and the correction data are obtained from the image information center located at the network address in the scanned image, not the scanned image itself obtained by scanning the printed image in this manner, the scanning noise is included. In addition, print data can be obtained from image data with higher precision than can be obtained by a normal scanner. For this reason, a reproduced image in which the printed image is reproduced with high precision can be printed.

In this image forming apparatus, image information including image data of a printed image and correction data for correcting conversion data used for converting image data into print data is received from the image information center. ing.
