An image processing apparatus includes: a storage unit that stores image information on which additional information is to be overlaid; a change unit that changes pixels, within a predetermined range of respective pixels constituting the image information, among pixels constituting the additional information, to pixels having a different density or color tint from a density or color tint of the image information and the additional information; and an overlay unit that overlays the additional information changed by the change unit on the image information held in the storage unit.

Image processing apparatus, image forming system, computer readable medium storing program and image processing method

A printing device includes a printer having a first printing part, a second printing part, and a reading sensor. The printer continuously prints printing data onto a printing medium. The first printing part in the printer first prints the printing data onto the printing medium by forming a mark indicating a page of the printing medium. The reading sensor subsequently reads the mark and matches printing surfaces of the printing medium to be printed by the first and second printing parts. The second printing part in the printer thereafter prints the printing data onto the printing medium. The printing device further includes an information holding part that previously holds information on a relationship between a size of the printing medium and a position of the mark, and a mark position setting part that movably sets the mark position based on the information held in the information holding part in accordance with the size of the printing medium.

Printing device using two printing parts and a reading sensor for continuous printing

A printing device includes a first printer and a second printer which continuously print one or plural pieces of printing data onto a printing medium. In the printing device, the second printer includes a reading sensor, the first printer first prints the one or plural pieces of printing data onto the printing medium by forming a mark indicating a page of the printing medium or each of the plural pieces of the printing data, the reading sensor in the second printer subsequently reads the mark and matches printing surfaces of the printing medium to be printed by the first and second printers, and the second printer thereafter prints the printing data onto the printing medium. The printing device includes an information holding part which previously holds information on a relationship between the mark position and a size of the printing medium or a size of each of the plural pieces of printing data, and a mark position setting part which movably sets the mark position based on the information held in the information holding part in accordance with the size of the printing medium or the size of each of the plural pieces of printing data.

Printing device, printing method, and computer-readable storage medium for printing using multiple printers

The present invention aims at providing a method of controlling a post-processor connected with an image-forming device that utilizes a conventional image-forming device and post-processing unit, and does not necessarily require to consistently form a sag in continuous paper. The inventive method of controlling the post-processor is carried out by the image-forming device that includes a transfer part and a fixing part, and conveys continuous paper. The image-forming device is connected with the post-processor that processed the continuous paper on which an image has been formed. The method comprises the steps of initiating an electrophotographic image-forming operation in the transfer part and the fixing part so that the image-forming device forms an image onto and conveys the continuous paper, initiating an operation of the post-processor so that the post-processor post-processes and conveys the continuous paper, stopping the operation of the post-processor on or before a completion of a transfer by the transfer part onto the continuous paper, conveying to the fixing part the continuous paper onto which the fixing part has finished transferring, and conveying to the transfer part the continuous paper onto which the fixing part finishes a fixation.
