Fig. 1 is the skeleton diagram that represents the ink-jet printer of embodiment.As shown in Figure 1, the ink-jet printer 1 of present embodiment comprises: balladeur train 2, and it can move back and forth along scanning direction S; Printhead unit 3, it is mounted on balladeur train 2; Ultraviolet lamp 4a, it is mounted on balladeur train 2, and is configured in the S front, scanning direction of printhead unit 3; Ultraviolet lamp 4b, it is mounted on balladeur train 2, and is configured in the S rear, scanning direction of printhead unit 3.Then, this ink-jet printer 1 along with the orthogonal direction of feed F of scanning direction S, by the amount of each medium transport path width, in addition, balladeur train 2 is moved along scanning direction S, carry out spraying ultraviolet hardening China ink the scanning from ultraviolet lamp 4a and ultraviolet lamp 4b irradiation ultraviolet radiation from ink gun 6, thereby on medium, form image.
Balladeur train 2 is retained as and can moves back and forth along scanning direction S in the top of the platen of pumped (conveying) medium (not shown).This balladeur train 2 is for example retained as can be upper mobile at the guide rail (not shown) extending along scanning direction S, by the driving of the driving mechanisms such as motor (not shown), can make this balladeur train 2 move back and forth on the S of scanning direction along guide rail.
Printhead unit 3 is the multiple ink gun 6(6a～6d that are assembled with for spraying ultraviolet hardening China ink) ink discharge device.In addition, because printhead unit 3 is mounted on balladeur train 2, therefore can in the time that moving, scanning direction S spray ultraviolet hardening China ink in the movement along with balladeur train 2.Then, ink gun 6a～ink gun 6d, along scanning direction S spread configuration, from scanning direction S front, is aligned in sequence with ink gun 6a, ink gun 6b, ink gun 6c and ink gun 6d.
On each ink gun 6, be formed with multiple nozzles (not shown) of the ejection using ultraviolet hardening China ink as drop.The plurality of nozzle forms the nozzle rows that the mode to extend along direction of feed F is arranged, and is formed with two is listed as this nozzle rows on each ink gun 6 along scanning direction S.Then, spray coloured ultraviolet hardening China ink (below also referred to as " color ink ") from the ink gun 6a and the ink gun 6b that are configured in S front side, scanning direction, spray the ultraviolet hardening China ink (below also referred to as " transparent China ink ") with light transmission from the ink gun 6c and the ink gun 6d that are configured in scanning direction S rear side.If describe particularly, spray the color ink of magenta (M) from being formed on the nozzle rows of the S front side, scanning direction ink gun 6a, spray the color ink of cyan (C) from being formed on the nozzle rows of the scanning direction S rear side ink gun 6a.In addition, spray the color ink of yellow (Y) from being formed on the nozzle rows of the S front side, scanning direction ink gun 6b, spray the color ink of black (K) from being formed on the nozzle rows of the scanning direction S rear side ink gun 6b.Then the two row nozzle rows that, formed separately from ink gun 6c and ink gun 6d spray transparent China ink (CL).
Then, in the nozzle rows being formed on ink gun 6a and ink gun 6b, only can not spray color ink from the nozzle rows not being configured at direction of feed F on first half from be configured in the nozzle rows ejection color ink of the ejection of first on latter half region A1 at direction of feed F.On the other hand, in the nozzle rows being formed on ink gun 6c and ink gun 6d, only spray transparent China ink and can not spray transparent China ink from the nozzle rows being configured on latter half at direction of feed F from the nozzle rows that is configured in the ejection of second on first half region A2 at direction of feed F.Therefore, when along direction of feed F pumped (conveying) medium, first, the color ink spraying from the first ejection region A1 of ink gun 6a and ink gun 6b is coated in the surface of medium, afterwards, after direction of feed F pumped (conveying) medium, the transparent China ink of the second ejection region A2 ejection from ink gun 6c and ink gun 6d is coated in to the upper strata (surface) of color ink.
In addition, illustrate that each ink gun 6 changes the device of the black kind spraying according to nozzle rows, but can be also only to spray a kind of China ink from an ink gun 6, the ink gun 6 suitable with the quantity of the black kind of expecting is assembled into the device forming on printhead unit 3.
Ultraviolet lamp 4a and ultraviolet lamp 4b are identical structure, and are to make the curing device of this ultraviolet hardening China ink to being coated in the ultraviolet hardening China ink irradiation ultraviolet radiation on medium.Therefore, below, merge ultraviolet lamp 4a and ultraviolet lamp 4b, describe as ultraviolet lamp 4.In addition, because ultraviolet lamp 4 is mounted on balladeur train 2, transmitting ultraviolet ray therefore can move back and forth on the S of scanning direction in the movement along with balladeur train 2 time.
Fig. 2 is the upward view of ultraviolet lamp, and Fig. 3 is the III-III line cutaway view of Fig. 2, and Fig. 4 is the IV-IV line cutaway view of Fig. 2.As shown in Figure 2 to 4, ultraviolet lamp 4 taking UVLED unit 41, reflecting plate 42 and mask 43 be main composition key element.
UVLED unit 41 is by multiple UVLED(ultraviolet LEDs) form, and each UVLED arranges along direction of feed F.In addition, in the present embodiment, on UVLED unit 41, be equipped with 8 UVLED.Irradiate and have the ultraviolet ray that directionality is higher from this UVLED unit 41, and the illumination having tilted in the direction of 60 ° with respect to vertical is 50% left and right of the illumination of vertical.
Reflecting plate 42 is devices that the ultraviolet ray of launching from UVLED unit 41 is reflected to side medium.This reflecting plate 42 is formed as in order to become the side surface of tetragonous cone table from UVLED unit 41 towards vertical below with the umbrella that roughly inclination of 60 ° is expanded.Then, transparent lid 42a is installed on the rectangular opening on the lower surface that is formed on reflecting plate 42, this lid 42a can seal the opening of reflecting plate 42 and ultraviolet ray is seen through.In addition, as mentioned above, because the ultraviolet directionality of launching from UVLED unit 41 is higher, therefore the ultraviolet illumination at the vertical direction of reflecting plate 42 below place is lower than the ultraviolet illumination at the vertical direction below place of UVLED41.
Mask 43 is formed as laminar, and the material being seen through by ultraviolet blocking-up forms, and this mask 43 is devices that the ultraviolet part adjustment of launching from ultraviolet lamp 4 by blocking-up is radiated at the ultraviolet illumination medium.
Fig. 5 is the figure that represents the relation between ultraviolet lamp and ink gun.As shown in Figure 5, ultraviolet lamp 4 is divided into the first irradiation area M1 of ultraviolet lamp 4, the second irradiation area M2 of ultraviolet lamp 4 and the 3rd irradiation area M3 of ultraviolet lamp 4, the first irradiation area M1 of this ultraviolet lamp 4 is corresponding with the first ejection region A1 of ink gun 6 on the S of scanning direction, the second irradiation area M2 of this ultraviolet lamp 4 is corresponding with the second ejection region A2 of ink gun 6 on the S of scanning direction, the 3rd irradiation area M3 of this ultraviolet lamp 4 on the S of scanning direction with ink gun 6 second ejection region A2 front corresponding.; the first irradiation area M1 is balladeur train 2 position (region) relative with the first ejection region A1 while moving along scanning direction S, and with via by corresponding the position (region) that is coated in the top, coating position medium from the color ink of the first ejection region A1 ejection.The second irradiation area M2 is balladeur train 2 position (region) relative with the second ejection region A2 while moving along scanning direction S, and with via by corresponding the position (region) that is coated in the top, coating position medium from the transparent China ink of the second ejection region A2 ejection.The 3rd irradiation area M3 is the position (region) of the direction of feed F front side of the second ejection region A2, and while moving along scanning direction S with balladeur train 2 by corresponding the position (region) of direction of feed F front side that is coated in the coating position medium from the transparent China ink of the second ejection region A2 ejection.Then, the 3rd irradiation area M3 becomes the region on direction of feed F with predetermined length.In addition, on direction of feed F, the backend arrangement of UVLED unit 41 is than the front of about 10mm on the front, the rear end of ink gun 6.
At this, with reference to Fig. 6 and Fig. 7, the Illumination Distribution of utilizing mask to adjust is described.Fig. 6 and Fig. 7 are the figure that represents to be radiated at the ultraviolet Illumination Distribution on medium.Illumination Distribution shown in Fig. 6 and Fig. 7 represents the Illumination Distribution of the illumination based on ultraviolet vertical composition.But, the ultraviolet ray of irradiating from ultraviolet lamp 4, not only there is vertical composition, also have the incline direction composition tilting with respect to vertical.But because the ultraviolet directionality of launching from UVLED unit 41 is higher, and separating distance between ultraviolet lamp 4 and medium is shorter, therefore, compared with the illumination of ultraviolet vertical composition, ultraviolet incline direction composition forms minimumly.Therefore, can think that to be radiated at the Illumination Distribution shown in ultraviolet Illumination Distribution and Fig. 6 and the Fig. 7 on medium roughly the same.
As shown in FIG. 6 and 7, be radiated at ultraviolet Illumination Distribution on medium be divided into the Illumination Distribution corresponding with the first irradiation area M1, with the corresponding Illumination Distribution of the second irradiation area M2 and the Illumination Distribution corresponding with the 3rd irradiation area M3.
The Illumination Distribution of the first irradiation area M1 is to make illumination entirety raise and can in the time that scanning direction S moves, make at ultraviolet lamp 4 the curing illumination of ultraviolet hardening China ink in the first whole region of irradiation area M1., the Illumination Distribution of the direction of feed F by S center, scanning direction is as follows: illumination raises towards direction of feed F front gradually from direction of feed F rear, and after welcoming the first peak illumination P1 that illumination is the highest, illumination reduces sharp in vicinity, rear end.The illumination that this first peak illumination P1 for example becomes vertical composition is 780mW/cm
2left and right.In addition, for example to become the illumination of vertical direction composition be 400mW/cm to the illumination of direction of feed F rear end
2left and right, although this illumination is lower than the first peak illumination P1, is still formed as making the curing illumination of ultraviolet hardening China ink.
The Illumination Distribution of the second irradiation area M2 is that the illumination of the amount of at least path width of direction of feed F rear side raises, and is formed as in the time that scanning direction S moves, making at ultraviolet lamp 4 the curing illumination of ultraviolet hardening China ink.In addition, the Illumination Distribution of the second irradiation area M2 is that the illumination of direction of feed F front side reduces and in the time that ultraviolet lamp 4 moves along scanning direction S, can not make the curing illumination of ultraviolet hardening China ink.; the Illumination Distribution of direction of feed F by S center, scanning direction is as follows: reduce illumination in the mode of going from direction of feed F rear towards direction of feed F front, at least the amount of path width is retained as the illumination that makes the curing degree of ultraviolet hardening China ink; afterwards; after reaching the bottom illumination B that makes the illumination that ultraviolet hardening China ink can be not curing, till rear end continues bottom illumination B.This bottom illumination B only otherwise ultraviolet hardening China ink is solidified, be no matter how scope illumination all can, for example, the illumination of vertical composition is 0mW/cm
2, or approach 0mW/cm
2value.
The Illumination Distribution of the 3rd irradiation area M3 is that the illumination of direction of feed F rear side reduces, and is formed as can not making the curing illumination of ultraviolet hardening China ink in the time that ultraviolet lamp 4 moves along scanning direction S.In addition, the Illumination Distribution of the 3rd irradiation area M3 is to make the illumination of direction of feed F front side raise and can in the time that scanning direction S moves, make at ultraviolet lamp 4 the curing illumination of ultraviolet hardening China ink.; the Illumination Distribution of direction of feed F by S center, scanning direction is as follows: illumination is gone towards direction of feed F front from direction of feed F rear and temporarily maintained bottom illumination B; raise gradually afterwards, welcoming the second peak illumination P2 lower than the first peak illumination P1, illumination reduces gradually afterwards.This second peak illumination P2 is than the low illumination of the first peak illumination P1, and for example, the illumination of vertical composition is 180mW/cm
2, become roughly 1/4 of the first peak illumination P1.
Therefore, in order to obtain such Illumination Distribution, mask 43 is configured on the position corresponding with rear portion on the direction of feed F of front portion to the three irradiation area M3 from the direction of feed F of the second irradiation area M2, and is arranged on the side medium of ultraviolet lamp 4.In addition, mask 43 can be by using adhesive tape, bonding agent etc. that this mask 43 is fixed on reflecting plate 42, lid 42a etc. and is carried out to the installation of ultraviolet lamp 4.
Fig. 8 is the top view that represents mask.In addition, in the following description, the width on the scanning direction S of mask 43 is only labeled as to " width ", the length on the direction of feed F of mask 43 is only labeled as to " length ".As shown in Figure 8, mask 43 is formed as taking the center by scanning direction S the line L that extends along the direction of feed F octagon as the line symmetry of benchmark, and this mask 43 is made up of rectangular the first position 43a, the leg-of-mutton second position 43b of direction of feed F rear side that is positioned at the first position 43a and pentagonal the 3rd position 43c that is positioned at the direction of feed F front side of the first position 43a.
The first position 43a is formed as rectangle, this rectangle be formed with the scanning direction S of lid 42a on the width of width same size, and this first position 43a covers from the second irradiation area M2 to irradiate the ultraviolet position of coming.Then, the width on the scanning direction S of lid 42a is 36mm, and the size of the first position 43a is that for example width is 36mm, and length is 15mm.
The second position 43b is formed as its width triangle of (going to expand gradually towards direction of feed F) that goes towards direction of feed F rear to narrow gradually, and this second position 43b covers from the second irradiation area M2 to irradiate the ultraviolet position of coming.Then, the width on the scanning direction S of lid 42a is 36mm, and the size of the second position 43b is that for example width (leg-of-mutton base) is 36mm, and length (leg-of-mutton height) is 5mm.
The 3rd position 43c is formed as its width and removes the pentagon narrowing with two stages towards the front of direction of feed F, and the 3rd position 43c covers from the second irradiation area M2 and the 3rd irradiation area M3 to irradiate the ultraviolet position of coming.Then, width on the scanning direction S of lid 42a is 36mm, and the size of the 3rd position 43c is that for example width (pentagonal base) is 36mm, and length (pentagonal height) is 25mm, the length of the inclination of first paragraph is 20mm, and the length of the inclination of second segment is 5mm.
Then,, as shown in Fig. 2～Fig. 5, the mask 43 forming is in the above described manner configured in than Gai42a center and is located on the front on direction of feed F.Then, make the rear end of mask 43 be positioned at than 41 center, UVLED unit by rear and locate on the front than the rear end of UVLED unit 41, for example, be positioned at than 41 center, UVLED unit by rear 5mm left and right place.In addition, the front end of mask 43 is positioned at than the front end of UVLED unit 41 and locates on the front.Thus, owing to irradiating and having the ultraviolet direct light of launching from UVLED unit 41 from the first irradiation area M1, therefore can irradiate the ultraviolet ray that illumination is higher, thereby owing to only irradiating and having the reverberation reflecting from reflecting plate 42 from the 3rd irradiation area M3, therefore can irradiate the lower ultraviolet ray of illumination compared with the first irradiation area M1.
Fig. 9 is the figure of the sensitization state of the sensitive paper represent ultraviolet lamp is lighted on sensitive paper in the situation that.In Fig. 9, P1 is the state that is illustrated in the sensitive paper while making under state that balladeur train 2 is static from ultraviolet lamp 4 irradiation ultraviolet radiation, and P2 is the state that is illustrated in the sensitive paper while making under state that balladeur train 2 moves along scanning direction S from ultraviolet lamp 4 irradiation ultraviolet radiation.As shown in Figure 9, on the position corresponding with the first irradiation area M1, whole sensitization of sensitive paper.On the position corresponding with the second irradiation area M2, only a part of sensitization of direction of feed F rear side, the not sensitization of a part of direction of feed F front side.On the position corresponding with the 3rd irradiation area M3, the not sensitization of a part of direction of feed F rear side, only a part of sensitization of direction of feed F front side.
As shown in Figure 9, if balladeur train 2 is moved along scanning direction S while ultraviolet lamp 4 is lighted, on the position corresponding with the first irradiation area M1, after the color ink of the first ejection region A1 ejection is coated in medium, illuminated ultraviolet ray at once and being cured.On the other hand, on the position corresponding with the second irradiation area M2, only locate in the lower floor of the second irradiation area M2, after the transparent China ink of the second ejection region A2 ejection is coated in medium, at once illuminated ultraviolet ray and being cured, but at the upper strata place of the second irradiation area M2, after the transparent China ink of the second ejection region A2 ejection is coated in medium, temporarily not illuminated ultraviolet ray, therefore surface becomes level and smooth.Then,, on the position corresponding with the 3rd irradiation area M3, be cured to the transparent black irradiation ultraviolet radiation from the second ejection region A2 ejection.
In the ink-jet printer 1 forming in the above described manner, along with the movement of balladeur train 2, spray transparent China ink from the first ejection region A1 ejection color ink of ink gun 6 and from the second ejection region A2 of ink gun 6, and from ultraviolet lamp 4 transmitting ultraviolet rays, and, with the amount of path width along direction of feed F successively pumped (conveying) medium, thereby on medium, form image.Therefore, on medium, be coated with color ink, be coated with transparent China ink on the upper strata of this color ink.
Then, owing to irradiating the ultraviolet ray of the Illumination Distribution that has the first irradiation area M1 in the color ink spraying from the first ejection region A1 of ink gun 6, therefore this color ink is after being coated on medium, and illuminated illumination is cured compared with high ultraviolet ray at once.
On the other hand, for the transparent China ink of the second ejection region A2 ejection from ink gun 6, first, irradiate the ultraviolet ray of the Illumination Distribution of the second irradiation area M2.Therefore, be coated to the transparent China ink of lower floor in the transparent China ink on medium after being coated on medium, illuminated ultraviolet ray at once and being cured, the transparent China ink on upper strata is after being coated on medium, not illuminated ultraviolet ray, therefore spreads and sinks in out along medium face, thereby makes the surface of medium become level and smooth.Afterwards, if medium is carried along direction of feed F, on the transparent China ink in upper strata that becomes level and smooth on surface, irradiate the ultraviolet ray of the Illumination Distribution of the 3rd irradiation area M3, the transparent China ink on this upper strata is solidified.
So, adopt the ink-jet printer 1 of present embodiment, ultraviolet irradiation by blocking-up from the direction of feed F upper forepart of the second irradiation area M2, can make to be coated in the abundant smoothing of transparent China ink (soaking) on upper strata, therefore can form the image fully with reflecting feel.
Then, by from the first ejection region A1 ejection color ink, spray transparent China ink from the second ejection region A2, can apply transparent China ink on the upper strata of color ink, and can make on the upper strata of color ink transparent black smoothing.Thus, can give reflecting feel to utilizing color ink to form image.
In addition, as the Illumination Distribution of the second irradiation area M2, the illumination of the amount of at least path width by rising direction of feed F rear side, and irradiation ultraviolet radiation on corresponding position, the rear portion with the second ejection region A2 on direction of feed F, can be coated in color ink directly over transparent black irradiation ultraviolet radiation.Thus, can improve the bond strength of color ink and transparent China ink.
In addition, by the Illumination Distribution of the first irradiation area M1 being made as to the curing illumination of ultraviolet hardening China ink that can make on the first whole region of irradiation area M1, can make after the color ink of the first ejection region A1 ejection is solidified the stacked transparent China ink from the second ejection region A2 ejection.Thus, can prevent that transparent ink penetration is in color ink.
In addition, as the Illumination Distribution of the 3rd irradiation area M3, by improving the illumination of direction of feed F front side, the transparent China ink that can make to be coated on upper strata solidifies after abundant smoothing, therefore can form rightly the image with reflecting feel.
Now, by the ultraviolet illumination of going towards direction of feed F to raise gradually and irradiate from the 3rd irradiation area M3, the transparent China ink that can make to be coated on upper strata solidifies gradually.Thus, the cure shrinkage sharply of transparent China ink can be suppressed, thereby striped and reduction reflecting feel between path can be suppressed to produce.
In addition, less than the peak illumination on the first irradiation area M1 by the peak illumination on the 3rd irradiation area M3 is made as, the curing rate of the transparent China ink on the upper strata of can slowing down.Thus, can further suppress to produce striped and reduction reflecting feel between path.
And, adopt present embodiment, because utilization is located at configuration, the shape etc. of the mask 43 on UVLED unit 41, can regulate the ultraviolet illumination being radiated on medium, therefore can adjust simply the ultraviolet Illumination Distribution of launching from ultraviolet lamp 4.
Then, the width of the second position 43b by making mask 43 goes to narrow gradually (going to widen gradually towards direction of feed F) towards direction of feed F rear, can go to reduce gradually towards direction of feed F the ultraviolet illumination being radiated on medium simply.
In addition, the width of the 3rd position 43c by making mask 43 goes to narrow gradually towards direction of feed F front, can be simply goes to raise gradually towards direction of feed F to being radiated at the ultraviolet illumination on medium.
