  • Patent number: 10828890
    Abstract: In an embodiment of the present invention, even though there is a print shift due to a gap between a nozzle in an upstream side and a nozzle in a downstream side of a printhead, a printing apparatus capable of precisely adjusting a slant of a printhead with respect to a conveyance direction in a nozzle surface of the printhead is provided. According to the embodiment, two adjustment patterns are printed at two different carriage speeds, respectively, and a print shift due to a slant of the nozzle surface of the printhead with respect to a conveyance direction of a print medium is adjusted based on these two print results.

  • Patent number: 10828889
    Abstract: It is often desirable to apply graphic output to surfaces that are large, irregular, and/or contoured. Application of graphic output on large or complex surfaces may be accomplished by projecting a pattern onto the surface using a projector disposed at a fixed location with respect to the surface. The graphic output is mapped to the projected pattern, by precisely positioning the print head with respect to the projected pattern using a robotic or similar actuated articulated positioning device, graphic output portions may be disposed in each of a plurality of defined locations to form a seamless, large scale graphic output.

  • Patent number: 10800163
    Abstract: A liquid ejecting apparatus includes: a support that extends in a second direction intersecting a first direction in which a printing medium is transported; a carriage that is connected to the support and is movable in the second direction; an ejector that is provided in the carriage and ejects a liquid to the printing medium; and a detector that is provided in the carriage and detects a change in posture of the carriage. In a case where the liquid is not ejected from the ejector, the carriage moves in the second direction, and the detector detects the change in posture of the carriage. The detector outputs posture-change amount information based on the change in posture of the carriage. Ejection of the liquid is corrected based on the posture-change amount information.

  • Patent number: 10800183
    Abstract: A method for reducing the effect of defective printing nozzles in a multicolor printing process on an inkjet printing machine. A computer creates a color transformation table that, for every process color of the inkjet printing machine, includes a replacement combination of the respective other process colors with a minimum color distance to the process color in question. The color transformation table is used to compensate for a defective printing nozzle. The color transformation table is created by printing and measuring a test chart with all process colors and interpolated by the computer. The color transformation table is then optimized to avoid undesired transitions between supporting points of the color transformation table and the resultant color transformation table accordingly contains process color combinations with minimum sensitivity to defective printing nozzles and the optimized table is used to carry out the multicolor printing operation on the inkjet printing machine.

  • Patent number: 10752028
    Abstract: A printing system includes a pair of encoders to compensate for encoder noise in the velocity of a media transport as the transport moves past a plurality of printheads. One encoder monitors a roller that positioned at a location of low thermal stress and the signal generated by this encoder is used by a controller to maintain a constant velocity for the media transport. The second encoder monitors a roller used to drive the media transport and is positioned close to the print zone opposite the printheads. The signal from the second encoder is used to identify a corrected distance between each tic in the tics generated by the second encoder and the corrected distance is used to count a firing distance for generation of a dot clock signal to activate ejectors in a printhead when a substrate has traveled the firing distance.

  • Patent number: 10710362
    Abstract: Disclosed is a method of providing adjustment data for a droplet deposition head (such as a printhead), or a data processing component therefor. The method makes use of test data, which has been collected by operating the droplet deposition head (or a test droplet deposition head of substantially the same construction, e.g from the same batch), using a set of test waveforms, at a number of frequencies within a test range, and by recording the volume and velocity of the thus-ejected droplets, with these recorded values (volr, velr) being represented within the test data. Each of the set of test waveforms includes a basic drive waveform and a number of adjusted drive waveforms, each of which corresponds to the basic drive waveform, but with a particular waveform parameter adjusted by a corresponding amount. This waveform parameter is a continuous variable, such as pulse width or pulse amplitude.
