Abstract
In prior art, there are some occasions where functions of a copy-forgery-inhibited pattern are impaired when printed on a sheet after rotation because of the level difference appearing between the density level of a latent image portion and the density level of a background portion of a copy-forgery-inhibited pattern. To cope with the problem, the image processing apparatus which has a generating unit for generating copy-forgery-inhibited pattern image data and a rotation unit for rotating the generated copy-forgery-inhibited pattern image data, wherein the generating unit generates the copy-forgery-inhibited pattern image data to be rotated by the rotation unit in accordance with a rotation angle in the rotation unit.
