摘要： A method for carrying out a printing operation on an inkjet printing machine compensates for failed printing nozzles by using a computer. After a screening process in which a halftone image is created for an image to be printed, failed printing nozzles are compensated for by increased ink application from neighboring printing nozzles by precalculating at least one corrective halftone image for the adjacent printing nozzles by using the computer, replacing the halftone image created in the screening process by the corrective halftone image in the at least one column of the neighboring printing nozzles, and carrying out the printing operation on the inkjet printing machine using the corrected halftone.

摘要： A recording device includes a recording unit, a scanning unit, and a recording control unit. The recording unit includes first and second recording parts each having multiple discharge orifice rows that each have multiple discharge orifices arrayed in a predetermined direction. The first recording part and the second recording part are separated from each other in an intersecting direction that intersects the predetermined direction. The scanning unit performs recording scanning by moving the recording unit. The recording control unit performs recording of a region on the recording medium including one edge of the recording medium by the first recording part alone, recording of another region including the other edge of the recording medium by the second recording part alone, and recording of a region in between the two regions using both recording parts.

摘要： An image processing device includes a first image generation unit which generates a first image obtained by applying a first low-pass filter to an input image, a second image generation unit which generates a second image obtained by applying a second low-pass filter to a halftone image, a third image generation unit which generates a third image representing a difference between the first image and the second image, a focused dot setting unit which sets a focused dot, a dot placement pixel determination unit which compares pixel values in the third image and determining a dot placement pixel for improving the uniformity of the gradation distribution in the third image, and a dot displacing unit which displaces the focused dot to the dot placement pixel and updates the halftone image.

摘要： A computer-implemented system for determining ink availability in one or more ink reservoirs in a print system is described. The system includes at least one ink reservoir for each color ink used in the printing system, a print unit associated with each ink reservoir configured to apply a print image including at least one color of ink to a substrate based on print image information, and an ink level monitoring system configured to determine an ink availability in each ink reservoir based on printed image count information including a number of printings of the print image and a total wet ink utilization generated based on a characterization of a print condition and further based on a measured dry ink utilization per area of coverage using the print image information and corrected by an ink usage correction multiplier.

摘要： A geographically remote computing device transmits an image to a central computing device. The geographically remote computing device also communicates specifications of a substrate or substrates to be imaged to the central computing device. The central computing device selects a geographically remote fulfillment printer. A local, but geographically diverse distribution system is available according to the invention. The central computing device chooses the geographically remote fulfillment printer as a function of factors such as the selected image and substrate, printer capabilities, and the consumer's location. Image quality and consistency is maintained by the central computer selecting an appropriate geographically remote computing device and providing printer the appropriate instructions, rather than the instructions for printing being determined locally at the printer.

摘要： White-balance is improved when printing on colored media, while minimizing the time and use of costly materials required by present approaches. In an embodiment, the typical solid white fill or background layer is altered by including in the white layer one or more of the other colors already available in the printer to shade this layer. Thus, a small amount of cyan, for example, helps balance a pink-ish (red) media; yellow is used for blue media; and magenta is used for green media; as well as combinations thereof. A combination of transparent process inks and opaque white helps to maintain brightness (luminosity).

摘要： A printer includes a control section that generates print data specifying the amount of image forming ink for forming an image and the amount of undercoating ink for forming an undercoat for each pixel on the basis of color information of pixels included in image data. Also, when the amount of the image forming ink to be used is small in each pixel included in the print data, the control section reduces the amount of the undercoating ink to be used to an amount smaller than that of when the amount of the image forming ink to be used is large.

摘要： Provided is an inkjet recording device and an inkjet recording method that can selectively perform a high-speed recording mode or a high-quality recording mode without requiring a process of changing configurations of nozzle rows. The head control section performs the discharge control by using all the nozzles belonging to the nozzle groups of respective colors as the usable range Ru in the case where the “high-speed mode” is designated by the mode designating section. On the other hand, in the case where the “high-quality mode” is designated, the head control section determines, for each color, the usable range Ru being a part of the nozzle range Rn configured by the nozzle groups, and performs the discharge control using only the nozzles belonging to the usable ranges Ru so as to cause the ink droplets to be discharged according to the particular color order at any positions on the recording medium.

摘要： An image forming apparatus includes a head; a scanning section; and a transport section. A first region is formed in the head between a nozzle formed at a first end and a first nozzle that is a first predetermined distance away, in the sub-scanning direction, from the nozzle formed at the first end. A second region is formed in the head between a nozzle formed at a second end and a second nozzle that is a second predetermined distance away, in the sub-scanning direction, from the nozzle formed at the second end. When the head, the scanning section, and the transport section form an image on the medium, a moving-average nozzle usage ratio within a region between the first region and the second region changes at a lower rate than moving-average nozzle usage ratios within the first region and the second region.

摘要： There is provided an ink-jet printer including an ink-jet head, a conveyance section, and a controller. The ink-jet head includes a plurality of nozzle groups. Between the plurality of nozzle groups, the nozzles forming the nozzle groups are positioned in conformity with each other, respectively, in a second direction. The controller causes the conveyance section to convey the recording medium between a first pass and a second pass such that the respective nozzle groups have partly overlapped scanning areas, and causes the ink-jet head to print separately between the first pass and the second pass in the second direction. The controller sets usable bordering positions in the overlapping range with respect to the passes. The controller sets the usable bordering positions based on one of such conditions as a duty of printing on the recording medium and a type of the nozzle groups to be used in printing.
