  • Patent number: 10105979
    Abstract: An inkjet printhead prints test patches of magnetic ink having magnetic particles using different ink droplet sizes on print media. A sensor scans the test patches to determine test patch densities. A processor determines a table-based density that produces a user-selected magnetic strength by applying the selected magnetic strength to a density and magnetic strength relationship table. The processor identifies a matching test patch as one of the test patches having a density that most closely matches the table-based density, identifies a selected droplet size as the ink droplet size used to print the matching test patch, and controls the printhead to produce magnetic ink droplets of the selected droplet size when printing a print job for the selected magnetic strength.

  • Patent number: 9533492
    Abstract: A dividing unit generates, from input data, divided data corresponding to the first area and the second area to be printed by a recording head and partly overlapping each other. The dividing unit supplies the respective divided data to the first processing unit and the second processing unit which can concurrently perform processing. Each of the first and second processing units generates the recording image data from the divided data based on a characteristic of the recording head corresponding to a recording area assigned to one of the processing units and a partial area assigned to the other processing unit. Each of the first and second processing units then performs driving control on the recording head based on data, in generated recording image data, which corresponds to an area recorded by one of the processing units.

  • Patent number: 9527280
    Abstract: For a lenticular in which a lens body having low shape accuracy is disposed on one end portion, when the other end portion of the lenticular is detected, a position of a carriage at the time of detecting the end portion of the lenticular is stored in a buffer as a paper end position, a carriage motor is controlled such that the carriage is separated from a home position and moved in a main scanning direction, and a printing head is controlled such that an ink discharge having a color according to printing data is started at the paper end position. Since the lens body having high shape accuracy is disposed on the end portion of the lenticular, it is possible to land the ink onto a more suitable position with respect to the lens body, thereby allowing printing quality to be improved.

  • Patent number: 9442369
    Abstract: An electro-deposition apparatus deposits a first pattern of a lithographic mask. The electro-deposition apparatus then deposits a second pattern of the lithographic mask, at least partially offset from the first pattern. The resulting lithographic mask includes a first pattern having a minimum feature resolution size and maximum pitch, and a second pattern having the same minimum feature resolution size and maximum pitch. The first pattern and second pattern are at least partially offset such that a fractional portion of the second pattern is realized and light transmission is more precisely controlled.

    Abstract: There are provided a liquid ejecting head having a high fabrication efficiency and a high reliability of an electric connector, and a fabricating method for the liquid ejecting head. A direction in which a channel forming member is incorporated to a casing crosses a direction in which a flat spring is resiliently deformed. In incorporating the channel forming member, an abutment portion formed at the flat spring is allowed to abut on the casing, thus deforming the flat spring. The flat spring is brought into contact with an inside contact pad by a resilient restoring force of the flat spring.

  • Patent number: 9302476
    Abstract: To provide a liquid ejecting apparatus which is able to eject a liquid where the surface tension is comparatively low in a stable manner. In relation to a driving signal for ejecting ink for textile printing where the surface tension is 22 [mN] or more and 30 [mN] or less from a nozzle, the interval between the first ejection driving pulse DP1 and the second ejection driving pulse DP2 and the interval between the second ejection driving pulse DP2 of a cycle T(n) and the first ejection driving pulse DP1 of a cycle T(n+1) are set to be ?t1. Due to this, in a case where medium dots are continuously formed over a plurality of continuous cycles, the ejecting intervals of the ink are set to be constant.

  • Patent number: 9283752
    Abstract: A method for printing an image on an image receiving member is provided, in which a print head having an array of print elements moves in a scanning direction to print image lines and the image receiving member is advanced in a transport direction after printing a swath. In order to obtain various contiguous swaths of print lines without a light or dark line between the swaths, the position of a prior swath printed preceding to a current swath is determined during the printing of the current swath. A digital mask is applied to the print data that is associated with the print elements at the to the prior swath adjoining edge of the current swath in dependence on the determination of the position of the prior swath.
