摘要:
An image recording apparatus that includes a recording head controller that transfers image data and a driving waveform to a recording head (25) in conjunction with position information of the recording head (9). The recording head controller (25) includes a driving waveform storage unit (251) that stores multiple driving waveform data, a number of driven nozzles calculator (252) that calculates the number of nozzles driven simultaneously from the image data, and a driving waveform selector (254) that selects one driving waveform data from the multiple driving waveform data based on the calculated number of driven nozzles and a predetermined threshold value of the number of driven nozzles.

A recording method using an inkjet recording apparatus, which can obtain a recorded material excellent in image quality and is excellent in productivity is provided. The present invention is a recording method using an inkjet recording apparatus 10 which performs recording on a travelling material to be recorded 1 by a line head 4, including: a first step S1 of setting resolutions to design regions of image data having a plurality of different design regions; a second step S2 of setting a travelling speed of the material to be recorded 1 so as to correspond to each of the resolutions; and a third step S3 of setting acceleration/deceleration of the material to be recorded 1 in order to connect different travelling speeds of the travelling speed, wherein the travelling speed of the material to be recorded 1 is changed during continuous recording by the line head 4.

The image forming apparatus (10) comprises: a recording head (12, 50, 50') which ejects droplets of a liquid onto a recording medium (16); a droplet ejection control device (200) which controls a droplet ejection timing of the recording head (12, 50, 50'); and a conveyance device (22) which relatively moves the recording medium (16) and the recording head (12, 50, 50') in a relative conveyance direction, wherein when the recording head (12, 50, 50') performs ejection of a first droplet to form a first dot on the recording medium (16) and then performs ejection of a second droplet to form a second dot overlapping with the first dot on the recording medium (16), the droplet ejection control device (200) controls the droplet ejection timing of the recording head (12, 50, 50') by taking a droplet diameter change time until a diameter of the first droplet deposited on a surface of the recording medium (16) reaches D1b satisfying the following inequality as a droplet ejection time interval between the ejection of the first droplet and the ejection of the second droplet: D1b

A print apparatus carries out printing by allowing an ink and a processing liquid that makes the ink insoluble to deposit on a printing medium in such a way that they are deposited on each other on a printing medium. A head (3) that ejects the ink or processing liquid and the printing medium are relatively moved in a primary scanning direction. A processing liquid droplet (16) and a black ink droplet (17) are sequentially ejected at the same positions in the direction opposite to the relative moving direction from the respective ejection ports provided at a predetermined space in the relative moving direction on the head (3). This configuration allows a splashing liquid droplet (19) caused by a subsequent black ink droplet (17) depositing on the processing liquid droplet (16) previously depositing on the printing medium at a position (X), to be ejected in the direction opposite to the relative moving direction of the head (3) and the printing medium, thereby preventing the splashing liquid droplet from splashing on a face (2) of the head (3) to deposit thereon.

Provision of a printing device having simple structure but being able to perform an exact and beautiful printing of designs and letters on a printed face of a doughnut-like shape such as a sidewall of a vehicular tire although. The printing device having a turntable for turning a mounted printing object so that its printed face is directed upward, a printing head having a plurality of nozzles for spouting inks and being able to move toward a center of rotation of the printing object from outside the rotation of the printed face, and a controller provided for controlling a moving speed of the printing head, a rotating speed of the turntable, and spouting of the inks by the plurality of the nozzles, to perform a controlling operation in a manner such that a printing is spirally applied onto the printed face of the printing object by permitting the printing object mounted on the turntable to be rotated and by permitting the printing head to continuously move while allowing the plurality of the nozzles to spout therefrom the inks.
