<P>PROBLEM TO BE SOLVED: To prevent creation of a printed matter whose information can not be read from a woven pattern even when area usable for embedding the woven pattern is reduced by processing that the woven pattern is performed in an image. <P>SOLUTION: An image extraction part 3 extracts printing data before embedding an embedding image and woven pattern data for generating the embedding image from image data, an image processing part 4 processes the printing data based on a predetermined printing instruction, a woven pattern editing part 7 updates the woven pattern data based on the printing instruction, furthermore, the printing instruction includes the minimum values of dot size, pitch width of the embedding image, when the dot size, the pitch width based on magnification becomes equal to or less than the minimum values, the woven pattern editing part changes the dot size, the pitch width to the minimum values regardless of the magnification and an image synthesizing part 8 embeds the woven pattern data after update by the woven pattern editing part 7 to output reproduced image data. <P>COPYRIGHT: (C)2008,JPO&INPIT |
