Abstract
According to an aspect of the present invention, by switching off the provisional curing device on the rear side in the direction of travel of the scanning direction, droplet ejection is carried out without performing provisional curing of the ink immediately after droplet ejection. The provisional curing of the ink is carried out by the provisional curing device on the front side in the direction of travel of the scanning direction, during scanning in the opposite direction to that during droplet ejection.
Claims8
An inkjet recording apparatus, comprising:
- a carriage which is equipped with:
- an emission unit which emits an active light beam;
- and
- an image forming unit which forms an image by inkjet ejection of color ink, clear ink, and white ink that are cured by the active light beam, wherein
- the carriage has a scanning device which bi-directionally scans a recording medium in a main scanning direction perpendicular to a direction of conveyance of the recording medium, and
- the emission unit includes provisional curing devices which are provided on both sides of the image forming unit in the scanning direction, and a main curing device which is provided on a downstream side of the conveyance direction of the recording medium,
- the inkjet recording apparatus further comprising a control unit which implements, when the color ink is ejected, droplet ejection of the color ink while switching on the provisional curing device on a front side in the main scanning direction, and switching off, immediately after the droplet ejection, the provisional curing device on a rear side in the main scanning direction.

An inkjet recording method, comprising:
- a recording medium conveyance step of conveying a recording medium;
- a scanning step of scanning the recording medium, in a main scanning direction perpendicular to a conveyance direction of the recording medium, by a carriage equipped with an emission unit which emits an active light beam and an image forming unit which forms an image by inkjet ejection of color ink, clear ink, and white ink that are cured by the active light beam, the scanning step being able to perform bidirectional scanning;
- an ink ejection step of ejecting the color ink, the clear ink, and the white ink by inkjet during the scanning step;
- a provisional curing device changing step of controlling, when the color ink is ejected, provisional curing devices provided on both sides of the image forming unit in the main scanning direction, so as to switch on the provisional curing device on a front side in the main scanning direction and so as to switch off, immediately after droplet ejection of the color ink by the ejection, the provisional curing device on a rear side in the main scanning direction;
- a provisional curing step of emitting the active light beam to an extent which incompletely cures the ink droplets which have become deposited to the recording medium, during scanning operation in an opposite direction to the main scanning direction in the ink ejection step;
- and
- a main curing step of emitting an active light beam which fully cures the ink droplets by carrying out additional exposure on the ink droplets which have been exposed in the provisional curing step.
