A cause identifying device includes a modifying unit and an identifying unit. The modifying unit, in a case in which an inexpedience is detected in an image formed on a print medium by conducting multiple processes, modifies processing content conducted during the image formation by modifying a processing parameter of a partial process or disabling a partial process. The identifying unit identifies a cause of the inexpedience on the basis of information obtained from an image formed on a print medium by image formation conducted after the processing content is modified.

Cause identifying device, image forming device, and non-transitory computer-readable medium

An image forming apparatus includes a level selecting unit, an image quality adjusting unit, and an image forming unit. The level selecting unit selects one of a plurality of levels each distributed to one of a plurality of adjustment items affecting an image quality determining factor that determines image quality. The plurality of adjustment items are different from each other. The image quality adjusting unit adjusts a value of each of the adjustment items belonging to the level selected by the level selecting unit and any other level shallower than the selected level such that the image quality corresponding to the image quality determining factor approaches predetermined image quality. The image forming unit forms an image having image quality according to the value adjusted by the image quality adjusting unit.

Image forming apparatus and image forming method for adjusting image quality

An image processing apparatus including: a first storage portion that stores patterns used for matching with edge portions of a linear image included in an input image, the patterns having respective different sizes, and each of the patterns being composed of pixels and including a target pixel corresponding to a pixel to be deleted in the linear image; a selection portion that selects a pattern having a size according to a line width of a line thinning process to the linear image, from the stored patterns; a pattern detection portion that matches the selected pattern with the linear image while shifting the selected pattern, and detects whether the selected pattern is matched with the linear image; and a deletion portion that, when the matching result is detected, deletes the pixel in the linear image corresponding to the target pixel in the selected pattern.

Image processing apparatus and non-transitory computer readable recording medium

A detection system includes: an acquiring unit that acquires document data representative of a document which includes a plurality of pages; a selector that selects, for each page of the document, a first printing sheet which contains a detected element or a second printing sheet which does not contain the detected element such that the first printing sheet is selected for at least one page; a supplier that supplies the first or the second printing sheet selected by the selector; a printer that sequentially prints the document acquired by the acquiring unit on the printing sheets supplied by the supplier; a detector that detects a detected element contained in a printing sheet on which the document is printed by the printer; and a reporter that reports detection of the detected element in a printing sheet by the detector.

Printing apparatus, detection system, and method computer readable medium for creating document

There is provided an image processing apparatus including: an image information acquisition unit that acquires image information representing an image obtained by reading a recording medium containing one or a plurality of detectable substances; an extraction unit that extracts an image corresponding to the detectable substances from the image information acquired by the image information acquisition unit; a computation unit that computes feature quantities of distribution of the detectable substances in the recording medium based on the image corresponding to the detectable substances extracted by the extraction unit; and a memory that stores the feature quantities computed by the computation unit.

Image processing apparatus and verification system

An image processing device includes a generating unit and an output unit. The generating unit generates image data on the basis of which an image forming unit forms a visible image on a recording medium containing detectable substances using only a coloring material having a spectral reflection factor that is different in a particular wavelength range from a spectral reflection factor that the detectable substances have by a predetermined threshold or more. The output unit outputs the image data generated by the generating unit to the image forming unit.

Image forming device forming a visible image on a medium containing detectable substances

An image processing device comprises: an obtaining unit that obtains a first image data set expressing a first face of a sheet-type material in which one or more objects to be tested is embedded, and a second image data set expressing a second face opposite to the first face; and a specifying unit that specifies a condition of the embedded one or more objects to be tested in the sheet-type material, depending on the first and second image data sets obtained by the obtaining unit.

In an ink amount limiting section there are obtained ink amount limiting coefficients which are used to limit the ink amounts of the respective colors in such a manner that, where the maximum number of times of repeated printing with respect to a unit pixel that can prevent the ink from being blurred and from soaking up to the back surface of the record medium is set for a given value, the maximum number of times of ordinarily repeated printing within the unit pixel can provide a limited repeated printing conversion number equal to or less than the above-set given value. And, based on the thus obtained ink amount limiting coefficients and the image signals of the respective colors output from the &ggr; correcting section print signals are generated and output. The print signals are quantized into the number of times of repeated printing in the halftoning section according to a multi-level error diffusion method, and the thus quantized print signals are dot printed repeatedly in the printing section to thereby form an image. In the print signals that are output from the ink amount limiting section since the number of times of repeating ink drops is limited to the given value or less, the number of times of repeated dot printing by the printing section is substantially equal to or less than the given number of times, thereby being able to reduce the possibility that the ink can be blurred and can soak up to the back surface of the record medium.

Ink jet recording apparatus

An ink jet recording method uses a plurality of recording heads, each of which jets droplets of ink of water-soluble dye of different color to record an image on a recording medium. The recording method includes the steps of: jetting a first ink from one of the plurality of recording heads to print on the recording medium, the first ink having an absorption coefficient (Ka) of 0.5 ml/m.sup.2 .multidot.ms.sup.1/2 or less and a wetting time (Tw) of 50 to 200 msec; and jetting a second ink from one of the plurality of recording heads to print on the recording medium, the second ink having an absorption coefficient (Ka) of 1.0 ml/m.sup.2 .multidot.ms.sup.1/2 or larger and a wetting time (Tw) of 20 msec or less.
