Description

  The present invention relates to an ink jet recording apparatus and a recording method.

  2. Description of the Related Art Conventionally, ink jet recording apparatuses that perform recording on a recording medium by discharging ink droplets from nozzles provided in a recording head are known. Among inkjet recording apparatuses, an inkjet recording apparatus for outdoor sign use generally uses a recording head that uses a piezoelectric element as a recording element, and uses an ink containing an organic solvent as a main solvent.

  When recording is performed using such an ink jet recording apparatus, a strong odor may be generated depending on the ink used. In recent years, when environmental awareness is increasing, there is a strong demand for reducing such odors.

  For the purpose of suppressing the odor of ink, there is an inkjet recording apparatus for outdoor sign use that uses water-based ink and an inkjet recording apparatus that fixes ink on a recording medium using ink that is cured by irradiation with UV light. It has been put into practical use.

  A recording medium in which vinyl chloride is used on the recording surface and the coating agent is not applied is mainly used in an inkjet recording apparatus for outdoor sign applications. However, in an inkjet recording apparatus that uses water-based ink and an inkjet recording apparatus that uses ink that is cured by irradiation with UV light, the gloss of the recorded image is poor because the ink does not sufficiently wet and spread on the recording medium, The recorded image may be faint.

  Accordingly, there is a demand for an ink jet recording apparatus that uses a solvent ink having a clean recorded image as a main solvent and a low odor ink. For example, Patent Document 1 discloses a low-odor inkjet ink containing diethylene glycol dialkyl ether and tetraethylene glycol dialkyl ether.

  On the other hand, various techniques for making it easier to handle a recorded matter recorded by an ink jet recording apparatus are disclosed. For example, Patent Document 2 discloses an ink jet recording apparatus provided with hot air drying means for blowing hot air onto a recorded material in order to dry the recorded material.

  However, as a result of intensive studies by the present inventors, the ink disclosed in Patent Document 1 certainly has a low odor, but depending on the ink jet recording apparatus that uses the ink, the ink is not firmly fixed on the recording medium. I found out that In general, with respect to so-called solvent inks containing an organic solvent as a main solvent, in order to reduce the odor of the ink, either a solvent with little odor is used or a solvent that is difficult to volatilize is used. For this reason, since a low-odor ink often uses a solvent that is difficult to volatilize, it may not be firmly fixed on the recording medium.

  Further, as a result of further intensive studies by the present inventors, it has been found that when the technique disclosed in Patent Document 2 is used, the effect may be insufficient depending on the ink used. In addition, when the recording surface of the recorded material is touched by hand, the time until the ink does not touch is shortened and the drying speed of the recorded material is improved, but the recorded image may be peeled off when the recording surface is rubbed, It was found that the ink may not be firmly fixed on the recording medium.

Accordingly, an object of the present invention is to provide an ink jet recording apparatus capable of firmly fixing a solvent ink having a low odor to a recording medium.
It is another object of the present invention to provide a recording method capable of firmly fixing the solvent ink on a recording medium even when a low-odor solvent ink is used.

The fixing property was evaluated by preparing an aqueous ethanol solution having an ethanol concentration of 70%, including this in a cotton swab, and rubbing the recorded matter with the cotton swab. Further, rubbing evaluation was performed 1 hour and 24 hours after recording each recorded matter. This evaluation was performed by evaluating how much the image of the recorded material was less scraped by rubbing than the result of rubbing evaluation of the recorded material recorded under the conditions of Reference 1 and Reference 2. The reference using IX as the ink is reference 1, and the reference using GX as the ink is reference 2.

The evaluation criteria for this evaluation are as follows.
○: The degree of image shaving is clearly less than that of the reference.
