Image forming apparatus

Abstract

Provided is an image forming apparatus that can reliably conceal character information of a concealing area even if the printing rate of a see-through preventive image is reduced. The image forming apparatus for printing print data on recording paper includes a concealing area determination part for determining a concealing area including a concealing character string in the print data; a character discriminating part for discriminating character attribute of the concealing character string; a see-through preventive image generation part for setting a see-through preventing area whose shape and size are the same as the concealing area, randomly generating multiple characteris of the character attributed discriminated by the character discriminating part, and generating a see-through preventive image obtained by configuring the generated multiple charactersto random positions in the see-through preventive area. The image forming apparatus generates the print data for see-through prevention obtained by configuring the see-through preventive image at overlapped positions in the same direction with the concealing area during enclosure and prints the print data on the recording paper.
本发明提供即使降低透看防止图像的印字比率也能够可靠地将隐匿区域的字符信息隐匿的图像形成装置。为此,作为将印刷数据印刷在记录纸上的图像形成装置,其具备:隐匿区域确定部,其在印刷数据中确定包含隐匿字符串的隐匿区域;字符判别部,其对隐匿字符串的字符属性进行判别;以及透看防止图像生成部,其设定形状及大小与隐匿区域相同的透看防止区域,并且随机地生成由字符判别部判别出的字符属性的多个字符,生成将所生成的多个字符分别配置在透看防止区域内的随机的位置而得到的透看防止图像,图像形成装置生成将透看防止图像配置于在封入时与隐匿区域以相同朝向重叠的位置而得到的透看防止用印刷数据,并印刷在记录纸上。
