    Abstract: An image forming apparatus includes recording heads for ejecting recording liquids of colors onto a recording medium. The apparatus includes a reference-patch forming unit that records a reference patch, the reference patch being formed by overlaying dot array patterns recorded with the recording liquids of different colors, the dot array patterns having no correlation therebetween; a detection-patch-group forming unit that records a detection patch group including detection patches, each of the detection patches being formed by overlaying dot array patterns recorded with the recording liquids of the different colors, the dot array patterns having a same cycle of regular dot array, the detection patches being allocated with different misregistration amounts of the dot array patterns; and a color-misregistration correcting unit that corrects color misregistration based on results of comparison between color tone of the reference patch and color tone of each of the detection patches.

  • Patent number: 8634109
    Abstract: An image forming apparatus has an image carrier carrying an electrostatic latent image, a charging unit charging the surface of the image carrier, an exposure unit forming an electrostatic latent image by irradiating light onto the charged surface of the image carrier, a developing unit developing the electrostatic latent image formed on the surface of the image carrier using a developing material, and a transfer unit transferring a developer image onto a printing material. The apparatus has also an image correction unit correcting image data inputted to the exposure unit so as to compensate for deformation in the developer image originating in a form of the exposure unit, and a smoothing processing unit carrying out smoothing of an image by controlling the exposure unit so that dots of a size smaller than one pixel are filled with respect to a white image region of the corrected image data.

  • Patent number: 8617776
    Abstract: A method and system for printing documents with one or more embedded security features is provided. Security features are embedded in the document by co-printing magnetic and non-magnetic toner on a receiver before fixation by a fixing station. The combination of magnetic and non-magnetic toners in the image results in image elements that easily show alteration or are undetectable by visual means.

  • Patent number: 8477376
    Abstract: A method for forming a variable data job includes a fixed original image provided by original image data in a first multiple channel color plane and content provided by variable image data in a second multiple channel color plane. The original image data is converted to fixed image data in a clear channel color plane. Raster image processing is performed on the fixed image data to translate the fixed image data into a first ready-to-print file. The ready-to-print file is saved in a memory as a post-RIP file. The variable image data is subsequently provided in at least the second multiple channel color plane. Image processing is performed on the variable image data to obtain a second ready-to-print file. The post-RIP file is merged with the second ready-to-print file for forming the variable data job. The variable data job is printed to render output.

  • Patent number: 8446597
    Abstract: An image forming apparatus includes a direct-transfer control unit that causes a direct-transfer medium and a first image forming unit that forms a single-color image to transfer the single-color image onto either the direct-transfer medium or a transfer sheet; an indirect-transfer control unit that causes an intermediate transfer medium and a second image forming unit that forms a multi-color image to transfer the multi-color image onto the intermediate transfer medium; a secondary-transfer control unit that transfers the single-color image onto the intermediate transfer medium; a sensor that detects an image on the intermediate transfer medium; and a positional-alignment control unit that calculates, using the sensor, an amount of misalignment of the image and corrects, using a position of an image formed by the first image forming unit as a reference position, positions of images to be formed by the second image forming unit based on the calculated amount of misalignment.

  • Patent number: 8411324
    Abstract: Line width of images marked by an image marking device is adjusted by reading a calibration patch marked by the marking device, and then adjusting one or more settings of the marking device, such as exposure intensity or cleaning field intensity, independent of the digital control of the tone reproduction curve so that the line width of subsequently marked images becomes closer to a target value. A digital control may be implemented to compensate for the impact of the modification of the one or more settings on the tone reproduction curve.

  • Patent number: 8305631
    Abstract: A method is provided for processing an image to optimize print time of the image by a print apparatus based on the size of the image to be printed and the print pass thresholds of the print apparatus. A dimension of the image corresponding to the dimension along the sub-scanning axis of the image as it will be printed by the print apparatus is obtained, along with the corresponding number of print passes required to print the image. An analysis is performed to determine whether the size of the image could be reduced to require one less print pass by the print apparatus in printing the reduced image based on the proximity of the determined dimension to the range of dimensions that will result in one less print pass by the print apparatus.
