Abstract: Provided is an image forming system including a first image forming device, a second image forming device; and an image reading device. A first hardware processor of the first image forming device causes a first image former of the first image forming device to form a first reference image on a first face of a sheet. A second hardware processor of the second image forming device causes a second image former of the second image forming device to form a second reference image different from the first reference image on the first face of the sheet. A third hardware processor of the image reading device determines whether an image positional deviation is present based on the first reference image and the second reference image that are formed on the first face of the sheet and that are read by the image reading device.
Abstract: An apparatus includes a specifying unit that specifies a color; an input unit that inputs an image; a converting unit that converts a color in the image, which has a hue within a predetermined range with respect to the specified color, into a color of a predetermined hue and converts a color in the image, which has a hue outside the predetermined range with respect to the color, into black; a printing unit that prints the image subjected to the converted color; and a counting unit that separately counts a number of sheets when the printed image includes the color of the predetermined hue and a number of sheets when the printed image does not include the color of the predetermined hue.

Abstract: There are provided a printing system, a method of generating a halftone processing rule, a method of acquiring a characteristic parameter, image processing device and method, a halftone processing rule, a halftone image, a method of manufacturing a printed material, an ink jet printing system, and a program which are capable of reducing an operation load of a user and acquiring a halftone processing rule appropriate for the printing system. A characteristic parameter acquisition chart including a pattern for acquiring characteristic parameters related to characteristics of the printing system is output, and the output characteristic parameter acquisition chart is read by image reading means. The characteristic parameters are acquired by analyzing the read image of the characteristic parameter acquisition chart, and halftone processing rules that define the processing contents of halftone processes used in the printing system are generated based on the acquired characteristic parameters.
Abstract: An image processing method is an image processing method of a recording device. The image processing method includes inputting the image data having a resolution in a sub scanning direction of X×N dpi, performing data processing on the image data for each N-unit region, performing resolution reduction processing of reducing, to 1/N, a resolution in the sub scanning direction, and generating a recording data based on the reduced image data. In the data processing step, when the N-unit region is formed of a pixel having a black gradation value and a pixel having a gradation value that is equal to or greater than a predetermined value when expressed by RGB, and the pixel having the black gradation value is consecutive from another N-unit region adjacent to the N-unit region, a black dot is generated in a pixel after the resolution reduction processing.
Abstract: Provided is an image forming apparatus that speeds up the auto color mode. The image forming apparatus includes a document reading unit that reads a document including a plurality of pages and outputs image data and can determine whether the document is a color document or a monochrome document. In the document read by the document reading unit, when monochrome pages of the first specific number of pages or more continues in the same job, a document determining unit predicts that the subsequent page is also determined to be a monochrome document. When the document is predicted by the document determination unit to be a monochrome document, an image processing unit performs monochrome image processing for the monochrome document on the image data immediately after reading.

Abstract: An apparatus configured to generate image data represented in achromatic color from input image data and output the generated image data to a printer includes a controller. The controller is configured to replace color information of an object included in the input image data with an achromatic signal value, determine, based on an achromatic signal value corresponding to color information of a pixel of interest in the input image data, whether the pixel of interest satisfies a predetermined condition, and perform enhancement processing on the color information of the pixel of interest in a case where the pixel of interest is determined not to satisfy the predetermined condition.
Abstract: Systems and methods are provided for evaluation of a print verification system. One embodiment is a print system that includes a printer, a virtual printer, a print verification system, and a print server. The print server is configured to initiate an evaluation of the print verification system by providing a defective version of a print job to one of the printer and the virtual printer and providing a non-defective version of the print job to the other one of the printer and the virtual printer. The print server verifies functionality of the print verification system based on whether the print verification system detects the defects via comparison of the printed output of the print job by the printer against the bitmap image output of the print job by the virtual printer.

Abstract: A method is provided of digitally imaging a secure portion and a non-secure portion of scratch-off-coating protected documents of at least one game using middleware. The method includes: (a) generating the secure variable indicia in non-vector raster format; (b) generating vector graphics to be imaged on physical document locations; (c) assigning the secure variable indicia in a non-vector raster format to documents in and shuffling the documents throughout a print run; and (d) linking via middleware the secure variable indicia in the non-vector raster format to associated vector graphics variable indicia to be digitally imaged on the documents and to generate vector graphics-formatted data for each document in the print run. The secure variable indicia assignment and shuffling are executed by non-vector raster game generation software output that is reinterpreted by the middleware to produce related vector graphic output for the secure variable indicia.
Abstract: A printing abnormality detection system includes a printer that prints an image on a printing medium based on image data, a reader that reads the image printed on the printing medium, a processing unit that detects an abnormal printed portion based on read image data from the reader, a storage unit that stores information of a display necessity determination criterion, and a display unit. The processing unit determines, based on the image data, the read image data, and the display necessity determination criterion, whether the abnormal printed portion is to be displayed on the display unit. When the processing unit determines that the abnormal printed portion is to be displayed, the processing unit executes a process of displaying, on the display unit, abnormal printed portion information including an image of the abnormal printed portion.
Abstract: A system determines an object-design for a three-dimensional model of an object. The object-design may exhibit a design continuity. The system breaks the object-design in to spatial patterns corresponding to the discrete surfaces making up the outward surface of the object. The system then generates flattened patterns by projecting the spatial patterns into a two-dimensional plane. The system prints the flattened patterns on to designated regions of material sheets in an orientation that preserves the design continuity of the object-design. The regions may be extracted from the sheets and then joined at their edges to form a cover for object that exhibits the continuity of the object design.
