    Abstract: To obtain a printing inspection device that an optimum binarization threshold value in the printing inspection device that captures an image including a two-dimensional code printed by a general-purpose printer such as an ink jet printer, as a multi-level image, creates a binary image from the multi-level image with a predetermined binarization threshold value, and then performs decoding. Before a practical printing inspection is performed, a read test is performed. The read test is performed on one or more inspection samples by binarizing a multi-level image with brightness values for all gradations as a threshold value. A range (maximum value and minimum value) of readable brightness values is obtained, and then a median value between the minimum value and the maximum value is used as a binarization threshold value for a two-dimensional code image in a practical printing inspection.

    Abstract: A driving method enables a liquid feeding apparatus using a driving element in the form of a membrane to feed a liquid at high liquid feeding accuracy. To this end, a voltage applied to the driving element is controlled in such a way as to repeat a first period in which the voltage is changed from a first voltage to a second voltage and a second period which is a longer period than the first period and in which the voltage is changed from the second voltage to the first voltage, and such that an inflection point is provided in each predetermined interval during the first period based on a Helmholtz vibration period unique to the liquid feeding apparatus.

  • Patent number: 11445088
    Abstract: A method of processing a contone image for single-pass printing uses a printing system having first and second aligned printheads supplied with a same ink. The method includes the steps of: providing the contone image at a first resolution in a printing direction; dithering the contone image using a combined dither pattern to provide a full halftone image at the first resolution; dividing the full halftone image into first and second halftone images at a second resolution in the printing direction, the second resolution being less than the first resolution; and sending the first and second halftone images to respective first and second printheads for printing. The combined dither pattern is a combination of a first dither pattern for the first printhead and a second dither pattern for the second printhead, the first dither pattern being different than the second dither pattern.

  • Patent number: 11383512
    Abstract: An inkjet recording device includes a nozzle, a pressure generator and a driver. The nozzle ejects ink. The pressure generator changes pressure on ink in an ink flow path that communicates with the nozzle by a predetermined drive operation. The driver makes the pressure generator perform the drive operation predetermined limes of at least twice at time points on a predetermined cycle, and makes the nozzle eject an ink droplet of an amount corresponding to a number of drive operations included in a set of drive operations. In a case in which the number of drive operations is two, the driver makes the pressure generator perform the drive operation twice with an interval twice as long as the cycle.

  • Patent number: 11376843
    Abstract: In a method of nozzle failure detection in an ink jet printer having a plurality of ejection units including a nozzle and an associated liquid chamber with an electromechanical transducer, nozzle failure detection is performed, for each ejection unit, with a given minimum detection frequency. Each nozzle failure detection includes energizing the transducer with a waveform that does not lead to the ejection of a droplet but creates a pressure fluctuation that is sensitive to whether or not the ejection unit is in a malfunction state; measuring the pressure fluctuation in order to detect the malfunction state; defining a mask pattern that is independent of image contents to be printed; and when an image is being printed, performing the nozzle failure detection steps for each ejection unit at timings at which the respective nozzles are in pixel positions that belong to the mask pattern.

  • Patent number: 11351789
    Abstract: A fluid ejection device includes a number of primitives, each receiving a same set of addresses and including a number of ejection chambers, each corresponding to a different address of the set of addresses and including a drive bubble formation mechanism and a drive bubble detect (DBD) mechanism. Input logic receives nozzle column data groups (NCG), each NCG including fire pulse groups (FPG), each FPG including DBD data having an enable value or disable value, and ejection data bits, each ejection data bit corresponding to a different one of the primitives. For each FPG of each NCG, activation logic identifies the FPG as a DBD FPG when the DBD data has the enable value and activates in each primitive the drive bubble formation mechanism and the DBD mechanism identified by the DBD FPG to perform a DBD measurement.
