    摘要： A liquid ejecting apparatus includes a head in which a first nozzle group, a second nozzle group, and a third nozzle group which have a plurality of nozzles are disposed in a predetermined direction, and that can eject a liquid on a medium, a main scanning unit that scans the head in a main scanning direction, a sub scanning unit that relatively moves between the head and the medium in a sub scanning direction intersecting the main scanning direction; and a control unit. When the liquid is ejected to form a plurality of raster lines on the medium, the control unit maintains fixed values for each total value of a nozzle usage rate of the first nozzle group, total value of a nozzle usage rate of the second nozzle group, and total value of a nozzle usage rate of the third nozzle group, corresponding to the respective raster lines.

    摘要： MTF characteristics of a concavo-convex forming apparatus change depending on the amount of amplitude of input data, the operation condition of the apparatus, etc., and therefore, it is not possible to form a concavo-convex shape with good characteristics only by applying the MTF correction technique widely known in the image processing field. A concavo-convex forming apparatus including an input unit configured to input concavo-convex data representing concavo-convex of an object to be printed, and a correction unit configured to perform correction in accordance with a plurality of frequency band of the input concavo-convex data and whose intensity is made higher for the larger amplitude on the input concavo-convex data based on frequency response characteristics in a case where concavo-convex is formed on a printing medium.

    摘要： With respect to mask data sets for a multi-pass mode, the disclosure implements a more appropriate mask data configuration. A printing apparatus 10 for performing printing in an inkjet mode includes an inkjet head, and a controller 20. The controller 20 controls the inkjet head such that the inkjet head performs printing on a medium 50 in a multi-pass mode. In each of a plurality of printing passes which is performed on each position of the medium 50, the controller controls the inkjet head such that the inkjet head ejects ink drops onto pixels designated by a mask data set. In a case where the spatial frequencies of the arrangement of ink dots which are formed on the medium 50 during a first printing pass of the plurality of printing passes are referred to as first frequencies, and the spatial frequencies of the arrangement of ink dots which are formed on the medium 50 during a second printing pass later than the first printing pass are referred to as second frequencies, the first frequencies are frequencies lower than the second frequencies.

    摘要： Methods and systems are described herein for driving droplet ejection devices with multi-level waveforms. In one embodiment, a method for driving droplet ejection devices includes applying a multi-level waveform to the droplet ejection devices. The multi-level waveform includes a first section having at least one compensating edge and a second section having at least one drive pulse. The compensating edge has a compensating effect on systematic variation in droplet velocity or droplet mass across the droplet ejection devices. In another embodiment, the compensating edge has a compensating effect on cross-talk between the droplet ejection devices.

    摘要： Provided is an inkjet recording device and an inkjet recording method that can selectively perform a high-speed recording mode or a high-quality recording mode without requiring a process of changing configurations of nozzle rows. The head control section 66 performs the discharge control by using all the nozzles 42 belonging to the nozzle groups 46 of respective colors as the usable range Ru in the case where the "high-speed mode" is designated by the mode designating section 64. On the other hand, in the case where the "high-quality mode" is designated, the head control section 66 determines, for each color, the usable range Ru being a part of the nozzle range Rn configured by the nozzle groups, and performs the discharge control using only the nozzles 42 belonging to the usable ranges Ru so as to cause the ink droplets 26 to be discharged according to the particular color order at any positions on the recording medium 12.
