  • Patent number: 9132638
    Abstract: An object is to shorten the printing time of an inkjet printer capable of forming a plurality of ink layers on a medium. An inkjet printer (100) includes an ink head unit (102) for ejecting ink toward a medium (M); a moving mechanism (130) for moving the ink head unit (102) in a left-right direction; a transfer mechanism (55) for transferring the medium (M) in a forward-rearward direction; and a control device (50). The control device (50) performs first printing of causing the ink head unit (102) to eject the ink while sequentially transferring the medium (M) forward and second printing of causing the ink head unit (102) to eject the ink while sequentially transferring the medium (M) rearward.

  • Patent number: 8794752
    Abstract: According to one embodiment, an inkjet printer includes an inkjet head for discharging each of a plurality of visible color inks onto a medium and discharging at least one fluorescent ink onto only portions of the medium when printing an image onto the medium, such that at least a first visible color ink of the plurality of visible color inks is discharged onto the portions of the medium, and at least a second visible color ink of the plurality of visible color inks is not discharged onto the portions of the medium. The plurality of visible color inks reflect light at respective wavelength ranges of the visible color inks. The at least one fluorescent ink reflects light at a wavelength range that is the same as a wavelength range of at least one of the plurality of visible color inks discharged from the inkjet head.

  • Patent number: 8393700
    Abstract: An inkjet recording apparatus is presented. The inkjet recording apparatus includes an ink head configured to move in left and right directions, comprising a plurality of nozzles arranged in a front-rear direction for discharging ink on a recording medium, wherein the ink is curable when irradiated with light from a first light emitting device or a second light emitting device, and a conveyor device configured to feed the recording medium in a direction, wherein the first light emitting device is configured to move integrally with the ink head and to apply light to the recording medium, and wherein the second light emitting device, disposed offset from the plurality of nozzles in the front-rear direction, is configured to turn on independent of the first light emitting device and to apply light to the recording medium.
