When data about plural book sheets, each belonging to one of plural chapters, are edited to bind the plural book sheets by a casing-in operation in such a manner that chapter range images, which indicate the respective ranges of the plural chapters, are displayed on an edge so that the chapter range images that are adjacent to each other are arranged at different positions from each other in the top-bottom direction, a marker image emphasizing the chapter range image is adjacent to the chapter range image indicating the range of a chapter having book sheets the number of which is less than or equal to a predetermined threshold.

Data editing apparatus and program

The printing deviceincludes a print control unitwhich, if an authentication print job data is received at a timing when transition from a ready mode to a sleep mode is about to occur, causes the printing deviceto transit to the sleep mode and, and if a normal print job data is received at the timing, causes a printing engine unitto print the normal print job data before transiting to the sleep mode.

Print device which, when authentication print job data at a timing when transition is about to occur is received, causes the print device to transition and interferes transition if normal print job is received

An image processing device includes a print image data generator and a density adjuster. The print image date generator generates print image data for each of colors to be used to print a document image from image data of the document image including a barcode image and a background image overlapped on the barcode image as a background. The density adjuster performs at least one of processing to reduce the density of the barcode image in at least any one of pieces of the print image data of colors including the barcode image and processing to reduce the density of the background image within a neighboring region that neighbors a bar of the barcode image in at least any one of pieces of the print image data of colors including the background image.

Image processing device and image processing method

A bookbinding system includes a printing device which performs printing on text sheets and a cover sheet, a bookbinding device which binds a book by case binding a sheet stack of printed text sheets with a printed cover sheet, and an information processor which outputs bookbinding print data to the printing device. The bookbinding system includes a text sheet retainer which retains one or more types of text sheets, an environmental condition detector which detects environmental conditions in the printing device, a setting unit which sets types and numbers of text sheets, and a sheet stack thickness prediction unit which calculates a prediction value of thickness of a sheet stack including text sheets to be bound, based on the thickness and numbers of sheets of respective types set by the setting unit, according to current environmental conditions detected by the environmental condition detector.

Bookbinding system

An image processing apparatus that prints a plurality of manuscript data onto sheets and folds the printed sheets into N (2&#x2266;N) equally sized divisions is equipped with: a manuscript size obtaining section that obtains sizes of the manuscript data; a reference size obtaining section that obtains a first reference size, set based on a unit size equal to the size of the sheets divided into N divisions, and M reference sizes, set based on the unit size multiplied by M (2&#x2266;M&#x2266;N); and an arrangement setting section that arranges manuscript data of the reference size or less at single surfaces from among a plurality of printing surfaces of the sheets formed by the sheets being folded, and arranges manuscript data of an (M&#x2212;1)th reference size or greater and an Mth reference size or less at M continuous surfaces from among the plurality of surfaces.

Image processing apparatus and processing program for arranging manuscript data on folded sheets

An external storage unit managing system that specifies an external storage unit related to use from a plurality of the external storage units. The external storage unit managing system includes: an external storage unit retrieval unit that recognizes the external storage units connected to a print data output apparatus; and an external storage unit deciding unit that decides the desired external storage unit in a case where a plurality of the external storage units are retrieved by the external storage unit retrieval unit.

Print data output apparatus and method

An image processing device (), which converts multivalued pixel values of an RGB color space corresponding to original colors of a multicolor original image into multivalued pixel values of a CMY color space corresponding to color inks used for printing in order to overprint a multicolor original with a plurality of color inks, includes: a color space coordinate conversion unit () configured to convert the multivalued pixel values of the RGB color space into the multivalued pixel values of the CMY color space corresponding to the color inks used for printing with reference to a color conversion LUT () for storing relationship between the multivalued pixel values of the RGB color space and the multivalued pixel values of the CMY color space; and a correction unit () configured to correct the multivalued pixel values of the CMY color space converted with reference to the color conversion LUT in response to the color inks used for printing and an overprint sequence thereof.
