    摘要: An image forming apparatus is provided. The image forming apparatus includes a recording head to discharge a liquid on a recording medium while scanning in a main scanning direction and a sub-scanning direction relative to the recording medium. The recording head includes a first nozzle array and a second nozzle array. The first nozzle array discharges the liquid in a first discharge amount per unit time per unit length in a longitudinal direction. The second nozzle array discharges the liquid in a second discharge amount per unit time per unit length in the longitudinal direction. The second nozzle array is shorter than the first nozzle array in the longitudinal direction and disposed not overlapped with the first nozzle array in the main scanning direction. The second discharge amount is larger than the first discharge amount.

    摘要: A method for printing an object using a color image printer is provided. The printer applies colorant dots having a flat shape. The object has an apparent surface with a locally varying color for representing a color image on the surface. The printer comprises a white colorant, that is applied as a background underneath a surface colorant for begetting a local color of the apparent surface. The invented method comprises the steps of: generating two-dimensional image data for composing the object in slices; determining a local surface orientation of the apparent surface of the object; and applying colorant material in accordance with the two-dimensional image data, wherein, in dependence on the local surface orientation, white colorant dots are deposited between other colorant dots to compensate a color effect of an orientation of a surface colorant dot relative to the local surface orientation.

    摘要: A print device includes a head, a recovery portion, a processor, and a memory. The head is configured to eject a first ink for base printing and a second ink for image printing. The first ink is ejected onto a print medium and the second ink is ejected on the base printing to print image printing. The recovery portion is configured to perform recovery processing. The recovery processing recovers an ejection performance of the first ink of the head. The memory stores computer-readable instructions. When the computer-readable instructions are executed by the processor, the processor acquires an integrated value of an ejection amount of the first ink. And the processor also determines, based on the acquired integrated value, whether to perform the recovery processing by the recovery portion.
