[ink-jet recording apparatus]

The ink jet recording method of present embodiment for example can be by once passing through the ink-jet recording apparatus of formula to well known The device of above-mentioned humidifier is equipped with to carry out.Fig. 1 is the structure for schematically showing the ink-jet recording apparatus of present embodiment At an example figure.As shown in Figure 1, the ink-jet recording apparatus 10 has and yellow, magenta, cyan, the colors of black Corresponding four ink jet head units 11 and the conveyer belt for continuously feeding the cloth and silk 100 as recording medium.Arrow in Fig. 1 Head X indicates the conveying direction of cloth and silk 100.

Fig. 2A is the figure of composition when schematically showing the vertical view of ink jet head unit 11, and Fig. 2 B is to schematically show spray Black head unit 11 from the side when composition figure, Fig. 2 C be schematically show ink jet head unit 11 from front see when The figure of composition.Ink jet head unit 11 as shown in Fig. 2A~Fig. 2 C, has and matches along the width direction of cloth and silk shown in arrow Y respectively It is set to multiple ink guns 111 of two column and the blow-off outlet 112 for blowing out humidifying air to cloth and silk 100.Ink gun 111 is consolidated It is scheduled in said conveyer belt.

Ink gun 111 configures in such a way that part each other is duplicate in the Y direction, configures as a whole very close to each otherly.Blowout Mouth 112 is the conduit of the opening with elongate rectangular extended along the Y direction from the central portion of Y-direction, is equivalent to humidifier. Blow-off outlet 112 is configured at upstream side compared with the ink gun 111 of X-direction, is extended in the Y direction with whole ink guns 111 at least The range of overlapping.Ink gun 111 is for example with ink chamber (not shown), pressure chamber and nozzle, with the oil for accommodating assorted ink Ink tank connection.Blow-off outlet 112 is for example connect with humidifier (not shown).

As shown in Figure 1, said conveyer belt has cricoid adhesiveness band 21, supports the backing roll 22 of adhesiveness band 21 and defeated It send roller 23 and is configured at the nip rolls 24 for clamping the position of adhesiveness band 21 with conveying roller 23.Adhesiveness band 21 is in mounting cloth and silk 100 mask is adhesive.Conveying roller 23 is constituted in a manner of rotatably freely driving, and backing roll 22 rotatably freely configures. In addition, nip rolls 24 is can close relative to conveying roller 23, remotely configure.

If driving said conveyer belt, cloth and silk 100 is continuously conveyed in X-direction.It should be noted that real in advance to cloth and silk 100 The pre-treatment of coating and its drying etc. of pretreatment liquid is applied.

] then, for cloth and silk 100, supplied for example from the blow-off outlet 112 of the ink jet head unit 11 of more upstream side with 2m/ seconds The humidifying air of 25 DEG C of 70RH%.By the supply of the humidifying air, the surface of cloth and silk 100 is wet to droplet of ink and lands When identical degree.Then, the 1st ink is sprayed from the part that is wet of the ink gun 111 to cloth and silk 100.The spray of further downstream Black head 111 also carries out similarly humidifying the ejection with the later ink of the 2nd ink.

In this way, for cloth and silk 100, only by making ink jet head unit 11 once all be expected the oil of color by being discharged from Ink forms desired image on the surface of cloth and silk 100.The cloth and silk 100 of image is formd by for above-mentioned pre-add as described above Heat, color development, cleaning and each process of drying.

[effect, effect]

If forming image on cloth and silk by the primary ink jet recording method by formula as described above, formation will not be produced The fine image of the fringing of the ink colors sprayed after raw.Its reason thinks as follows.

Fig. 3 A is to schematically show the 1st ink penetration in the figure of the state of cloth and silk, and Fig. 3 B is to be shown schematically in the 1st It is humidified before will the spraying of ink, to the 2nd ink sprayed when the cloth and silk after the 1st ink further sprays 2 ink Permeate in the figure of the state of cloth and silk, Fig. 3 C be do not carry out humidifying before being shown schematically in the ejection of the 1st ink to spraying the 1st The 2nd ink penetration when cloth and silk after ink further sprays 2 ink is in the figure of the state of cloth and silk.

If spraying ink (such as ink of cyan) to cloth and silk, as shown in Figure 3A, the position landed with the drop of ink Centered on, ink permeates while the direction on the surface along cloth and silk and depth direction extend in cloth and silk.Here, if cloth and silk Dry, then the water soluble polymer that ink is attached in the above-mentioned pretreating reagent of the fiber of cloth and silk is seeped while absorption Thoroughly.If cloth and silk is wet, ink penetration is in the cloth and silk for the state that above-mentioned water soluble polymer has been swollen, therefore, with cloth and silk Dry situation is compared, and ink is more difficult to permeate in the thickness direction of cloth and silk, it is easier in the Directional Extension along surface.

When spraying cyan ink, if cloth and silk to be moistened to the profit generated to the land with the drop by the ink in advance Wet identical degree, then cyan ink by with extended on the cloth and silk for sprayed ink it is identical in a manner of be extended, permeate In cloth and silk.

At this point, if followed by spraying Yellow ink to the same position of cloth and silk in cyan ink, it is as shown in Figure 3B, yellow Infiltration is in cloth and silk while color ink is extended in a manner of identical with cyan ink.It is thought that when due to cyan ink infiltration The partial status of cloth and silk when partial status (such as swelling situation of water soluble polymer etc.) and the Yellow ink infiltration of cloth and silk It is substantially the same.As a result, the part that Yellow ink infiltration is substantially the same in the part permeated with the cyan ink in cloth and silk, Form the ink dot of green.

On the one hand, when spraying cyan ink, in the case where cloth and silk does not as above moisten (drying), the yellow that then sprays Ink and the cyan ink permeated while being swollen the water soluble polymer in the cloth and silk that water soluble polymer is not swollen It compares, it is more difficult to be permeated in cloth and silk.It is thought that due to compared with cyan ink, the flow path and water solubility of Yellow ink infiltration Macromolecule swelling correspondingly narrows.As a result, Yellow ink is as shown in Figure 3 C, compared with the part of cyan ink infiltration, on edge The direction on the surface of cloth and silk further expand, infiltrate into the outside of the ink dot of green.Therefore, it is formed in the figure on the surface of cloth and silk As the fringing (arrow in Fig. 3 C) of the yellow sprayed after foring.

On the other hand.When spraying cyan ink, if cloth and silk exceedingly moistens (for example, soaking like that containing liquid), Then cyan ink and Yellow ink infiltrate into broader range from landing positions in cloth and silk.Due to the volume of the drop of ink Limited, therefore, if ink is further permeated to the direction on the surface along cloth and silk, thickness direction, the tone of the ink shoals, Sometimes show with being unable to fully on the surface of cloth and silk.In addition, since ink so excessively extends, it is formed in cloth and silk sometimes Surface image in different tones between boundary become more unclear.As a result, the fineness of image further drops sometimes It is low.

Here, compared with spraying the ink-jet recording apparatus of the scanning mode of ink while ink gun is on one side Multiple-Scan, In the ink-jet recording apparatus, ink gun is mobile along left and right (such as Y-direction in Fig. 2A), in addition, ink per unit time Spray volume is usually smaller than once passing through the ink-jet recording apparatus of formula.Therefore, the image of the ink-jet recording apparatus of scanning mode is utilized It is formed compared with using once being formed by the image of the ink-jet recording apparatus of formula, ink is easy drying, wet in recording medium Degree is easy to stabilize.Therefore, the environment around recording medium when the 1st drop sprays and when the 2nd drop sprays will not significantly change, no Meeting substantially influences to land on the spread scenarios of the ink of recording medium.

In addition, the ink-jet recording apparatus of scanning mode usually forms image by the mode of interlocking.Thus, for example, cyan is oily Ink land on Yellow ink land position the case where and Yellow ink land on cyan ink land position the case where it is random It ground and is generated in recording medium (cloth and silk) entirety with the ratio of same degree.Therefore, even if landing on the Huang of same position The dot diameter of the dot diameter of color ink and cyan ink is different, also due to the part of different land sequences is randomly but greatly The part for foring image for being equally present in recording medium is caused therefore to be integrally formed the small image of incongruity.

In contrast, in being formed using the primary image by the ink-jet recording apparatus of formula, ink gun is not moved, and is swept The ink-jet recording apparatus for retouching mode is compared, and the spray volume of ink usually per unit time is more.Therefore, the humidity near ink gun It is easy to get higher.Therefore, the environment around recording medium when the 1st drop sprays and when the 2nd drop sprays is substantially different, lands on record Also there is difference in the spread scenarios of the ink of medium.

In addition, ink gun is fixed in the ink-jet recording apparatus once by formula, the ejection sequence of usual ink is consolidated Fixed (being then cyan ink etc. for example, being initially Yellow ink).Therefore, though Yellow ink dot diameter and cyan Subtle difference is generated between the dot diameter of ink, caused by also enhancing because of the difference in being formed by image entirety not Coordinate sense, as a result, forming the big image of incongruity.

These are to form specific project by the image of the ink-jet recording apparatus of formula using primary, according to the present invention, It is formed even with primary by the image of the ink-jet recording apparatus of formula, it is upper caused by will not substantially generating because of land sequence The difference for the dot diameter stated solves the distinctive project.

It can be seen from the above explanation the ink jet recording method of present embodiment be will containing aqueous medium and colorant two Kind or more ink the absorption with above-mentioned aqueous medium is ejected by single pass of the ink gun in aforementioned recording medium Property recording medium surface and form the ink jet recording method of image, aforementioned recording medium is cloth and silk or non-woven fabrics, above-mentioned spray Black recording method includes to carry out before above-mentioned ink is ejected into aforementioned recording medium to the above-mentioned surface of aforementioned recording medium The process of humidification.Therefore, even if forming figure in the recording medium of absorbability by the ink jet recording method once by formula As when be also capable of forming fine image.

In addition, in above-mentioned humidification process, from the viewpoint of the wetness conditions for suitably adjusting aforementioned recording medium, Further effectively above-mentioned surface is humidified using the air that relative humidity is 50~80%.

In addition, from keeping each ink consistent to the penetration degree of recording medium, being formed more high-precision in above-mentioned humidification process From the viewpoint of thin image, further effectively above-mentioned surface is added before the ejection of each above-mentioned ink It is wet.

In addition, above-mentioned ink jet recording method can be applied to print and dye, fine is formed on cloth and silk from high production rate From the viewpoint of image, it is even furthermore preferable that aforementioned recording medium contains the infiltration for preventing above-mentioned ink on above-mentioned surface The pretreating reagent of color.

In addition, the ink sprayed after being allowed to from the excessive swelling for the water soluble polymer for inhibiting cloth and silk it is readily permeable in Viewpoint and its result in cloth and silk are formed from the viewpoint of the image of more fine, are more effectively that above-mentioned ink contains binary The content of alcohols, the di-alcohols in the ink is 15~60 mass %, further effective from the viewpoint of above-mentioned The content for being the above-mentioned di-alcohols in above-mentioned ink is 30~60 mass %.

In addition, the ink-jet recording apparatus of present embodiment is that have for one side relative to recording medium relatively along one Direction is mobile to be sprayed ink on one side and forms the ink gun of expected image to aforementioned recording medium by single pass and be used for The conveyer for keeping aforementioned recording medium and moving above-mentioned ink gun relatively in one direction relative to aforementioned recording medium The primary ink-jet recording apparatus by formula of structure, aforementioned recording medium are cloth and silk or non-woven fabrics, are further had for above-mentioned The humidifier that the surface of the part in the front of the scanning direction of the above-mentioned ink gun of recording medium is humidified.Therefore, even if It is fine being also capable of forming by the ink jet recording method of formula when forming image in the recording medium of absorbability by once Image.

In addition, the wetness conditions of the cloth and silk before making to spray ink are constant between assorted ink, make assorted oil From the viewpoint of the extended mode of ink is consistently consistent, further effectively above-mentioned ink gun has for spraying a variety of face Multiple nozzle sets of the ink of color, said nozzle group spray the ink of different colours, above-mentioned humidifier and said nozzle respectively Group respectively correspondingly configures fronts that are multiple, and being configured at the above-mentioned scanning direction of said nozzle group.

[variation]
