Abstract
An ink jet printer for forming an image on a recording medium with an active-ray-setting ink, which is hardened by an irradiation of active rays; having a plurality of heads, each of the plurality of heads having a plurality of jet openings for jetting the active-ray-setting ink as ink drops towards the recording medium; and a plurality of active ray sources of irradiate active rays for hardening the ink drops of the active-ray-setting ink landed on the recording medium, wherein each of the plurality of heads and each of the plurality of active ray sources are arranged alternately.
Claims16
An ink jet printer comprising:
- a plurality of heads, each of the plurality of heads having a plurality of jet openings for jetting an active-ray-setting ink as ink drops towards a recording medium;
- and
- a plurality of active ray sources to irradiate active rays for hardening the ink drops of the active-ray-setting ink on the recording medium,
- wherein each of the plurality of heads and each of the plurality of active ray sources are arranged alternately, and
- wherein a time interval from a landing of an ink drop, which is jetted from any one of the plurality of heads, to a first irradiation of the ink drop by active rays from any one of the plurality of active ray sources falls within a range of 0.001 second to 0.4 second.
An ink jet printer comprising:
- a plurality of heads, each of the plurality of heads having a plurality of jet openings for jetting an active-ray-setting ink as ink drops towards a recording medium;
- a plurality of active ray sources to irradiate active rays for hardening the ink drops of the active-ray-setting ink on the recording medium;
- and
- a mobile body which is movable in a main scanning direction relatively to the recording medium, and which is provided with the plurality of heads and the plurality of active ray sources in such a way that each of the plurality of heads and each of the plurality of active ray sources are arranged alternately in the main scanning direction.
An ink jet printer comprising:
- a plurality of heads, each of the plurality of heads having a plurality of jet openings for jetting an active-ray-setting ink as ink drops towards a recording medium;
- and
- a plurality of active ray sources to irradiate active rays for hardening the ink drops of the active-ray-setting ink on the recording medium,
- wherein the plurality of heads and the plurality of active ray sources move relatively to the recording medium in a sub-scanning direction, and each of the plurality of heads and each of the plurality of active ray sources are arranged alternately in the sub-scanning direction.
An ink jet printer comprising:
- a plurality of heads, each of the plurality of heads having a plurality of jet openings for jetting an active-ray-setting ink as ink drops towards a recording medium;
- a plurality of active ray sources to irradiate active rays for hardening the ink drops of the active-ray-setting ink on the recording medium;
- and
- a transporting mechanism for transporting the recording medium in a sub-scanning direction,
- wherein each of the plurality of heads and each of the plurality of active ray sources are arranged alternately.
An ink jet printer for forming an image on a recording medium with an active-ray-setting ink, which is hardened by an irradiation of active rays, comprising:
- a mobile body movable in a main scanning direction relatively to the recording medium;
- an active ray source provided on the mobile body for irradiating the active rays to the recording medium;
- and
- a plurality of lines of jet openings, each line of the plurality of lines of jet openings having a plurality of jet openings, for jetting the active-ray-setting ink as ink drops towards the recording medium,
- wherein the plurality of lines of jet openings are arranged at both sides of the active ray source in the main scanning direction.
An ink jet head unit comprising:
- a plurality of lines of jet openings for jetting an active-ray-setting ink as ink drops, wherein each line of the plurality of lines of jet openings includes a plurality of jet openings arranged linearly on different lines respectively;
- and
- an active ray source provided between said plurality of lines of jet openings for emitting active rays for hardening the active-ray-setting ink.
