Patent number: 7480413Abstract: An image processing device is structured such that an appropriate judgement of an image, at which blurring or disappearance or the like will occur, is possible. When pixels, which form a line image at which there is the possibility that blurring or disappearance will occur at the time of printing by using a printing plate, are extracted, a line image warning function gives notice by displaying a warning message on a monitor of a client terminal. Thereafter, image converting and print setting are carried out such that an extracted line image is clarified. In this way, when a proof is prepared, an image, at which there is the possibility that blurring or disappearance will occur on a printed matter obtained by using a printing plate, is clarified, and appropriate proofing is possible.Type: GrantFiled: December 29, 2006Date of Patent: January 20, 2009Assignee: Fuji Xerox Co., Ltd.Inventors: Ryuichi Ishizuka, Mari Kodama, Yasushi Nishide

Patent number: 7468811Abstract: The present invention provides an image processing device and an image processing method, which prevent printing mishaps from occurring in printed matter when a user performs a printing process by using a machine plate without knowing a compressed image is included on a page layout. In the print server, when a compressed image on a page layout is detected, a warning is generated to request selection of the next process. For this reason, when interruption of printing is designated, the printing process is interrupted. Drawing using a warning color or application of an outline is designated, and a drawing setting is performed according to the designation. An output of a warning page is designated, and a setting is performed such that a print output is obtained by either extracting a compressed image or by deleting a compressed image.Type: GrantFiled: March 18, 2003Date of Patent: December 23, 2008Assignee: Fuji Xerox Co., Ltd.Inventors: Ryuichi Ishizuka, Mari Kodama, Yasushi Nishide

Patent number: 7355749Abstract: The present invention provides an image processing method and an image processing apparatus for properly enabling a compressed image included in a page layout to be drawn in colors. A print server detects a compressed image in an EPS (JPEG) format or the like, sets a CMS according to the color plate being processed, and converts values of C, M, Y, and K. For example, when a process on the C color plate is performed, the converting process is performed by using a CMS 40C for the C color plate so that the value of ācā in the compressed image becomes a value of K (KC value). In such a manner, the values of K (KC, KM, KY, and KK) output from CMSs 40C, 40M, 40Y, and 40K are converted into values of C, M, Y, and K.Type: GrantFiled: March 18, 2003Date of Patent: April 8, 2008Assignee: Fuji Xerox Co., Ltd.Inventors: Yasushi Nishide, Mari Kodama, Ryuichi Ishizuka
