  • Patent number: 8335014
    Abstract: A test pattern containing plurality of patches recorded using small dot patterns and large dot patterns is printed. The dot sizes arranged in the patches are different between patches. Then the test patterns are read. The detection rate and average density of additional information embedded in each large dot pattern are obtained. A large dot pattern whose detection rate and average density fall within a reference range and are closest to ideal values is determined. The average density of each small dot pattern is obtained. A small dot pattern whose average density falls within a reference range and is closest to the average density of the determined large dot pattern is determined. A copy-forgery-inhibited pattern image is generated using these dot patterns and combined with a print target image.

  • Patent number: 8328316
    Abstract: This invention is directed to provide an inkjet printhead, printing apparatus, and printing method capable of correcting a shift of the printing position caused by variations of the discharge characteristic between nozzles. To accomplish this, the inkjet printhead includes memories which hold block numbers used to time-divisionally drive nozzles. The block numbers are written in consideration of the discharge characteristics of the printhead during the manufacturing process of the printhead. When the inkjet printhead is mounted in the printing apparatus, the printing apparatus reads out block numbers corresponding to respective nozzles from the memories. Based on the numbers, the printing apparatus changes block selection signals for the respective nozzles, and transfers the changed block selection signals to the inkjet printhead to drive it.

  • Patent number: 8328310
    Abstract: A multipass printing is performed by setting the print permission ratios, predetermined for the nozzles in adjoining first and second blocks, in a way that satisfies the following conditions (i) and (ii). (i) The print permission ratio in the boundary section between the first and second blocks represents a value between the print permission ratio in the non-boundary section of the first block and that of the second block. (ii) The print permission ratios in the non-boundary sections of the first and second blocks are each set substantively constant. This arrangement allows the print permission ratio to be adjusted among nozzle blocks, thus satisfying the condition that the print permission ratio in a boundary between adjoining nozzles blocks does not change sharply and that the print permission ratio is substantively constant in each of the nozzle blocks. It is possible to suppress “interband variations”, “seam lines” and “intraband variations” coincidentally.

  • Patent number: 8328190
    Abstract: A sheet feeding apparatus capable of obtaining a sufficient conveying force for pulling back double-fed overlapping sheets to a stacking tray side. A sheet feeding member feeds sheets incoming from a stacking tray which stacks the sheets into a conveying pass. A separating member separates the sheets fed to the conveying pass by the sheet feeding member one by one. A double feed detection sensor generates an output for detecting double feed of sheets fed to the conveying pass. A rotatable member contacts the fed sheet. A driving unit rotationally drives at least the rotatable member in a rotational direction for reverse feeding of sheets. A control unit controls the driving unit when the double feed of sheets is detected based on the output of the double feed detection sensor, such that the rotatable member is rotationally driven in the rotational direction for reverse feeding of sheets.
