Description

  The present invention relates to a recording apparatus capable of performing band feeding and band recording corresponding to a nozzle row length of a recording head with respect to a recording surface of a recording material, and a method of manufacturing a recorded matter using the recording apparatus. .

Conventionally, band feeding corresponding to the nozzle array length of the recording head has been performed on the recording surface of the recording material, and recording for the nozzle array length, that is, band recording for performing band recording all at once. A corresponding recording apparatus is provided as shown in Patent Document 1 below.
The band feed recording is often used in large-scale inkjet printers and the like that support high-speed recording that requires a large recording area to be recorded in a short time, such as posters and wallpaper, because the recording speed increases.

In the conventional band feed recording, as shown in Patent Document 1 below, the band feed amount for feeding the recording material in the transport direction is set to the same length as the nozzle row length of the recording head. The ink is not ejected at the boundary between the ink ejected to the recording surface by recording and the ink ejected to the recording surface by the next band feed recording.
Also, with the advent of fast-drying pigment inks and UV inks, two different ink layers are continuously laminated on the same recording surface using two different inks, for example, a base ink and an image forming ink. Recording devices that can be formed in a state have also been developed.

However, in the case of the band feed amount having the same length as the nozzle row length of the recording head described above, there is a problem that the thickness of the ink layer at the band boundary portion is likely to vary. This is due to the fact that the thickness of the ink layer ejected to the band end portion is smaller than the thickness of the ink layer ejected to the band intermediate portion. This tendency is noticeable when UV ink is used in which the cured ink layer is formed with the thickness of the ejected ink layer being small as the ink thickness changes little before and after curing.
The problem is that when a two-layer ink layer is formed by separately ejecting a base ink and an image forming ink onto a transparent film-based recording material, Due to the variation in the thickness of the ink, the image quality is degraded.

  In addition, when label recording is performed by band feeding recording on the transparent film-based recording material using the base ink and the image forming ink, the band in which the individual images to be labeled are adjacent to each other are recorded. In the case where the image is located across the boundary portion or the size of the image exceeds the nozzle row length of the recording head, there is a problem that the influence of the ink thickness variation at the band boundary portion is affected.

[Example 1] (see FIGS. 1 to 12)
In the inkjet printer 1A according to the present embodiment, the control unit 21A executes band recording using the first band feed amount D1 where the boundary portion 49 of the band 47 adjacent in the transport direction A overlaps. 1 band-feed recording mode 61, and a second band-feed recording mode 62 that executes band-feed recording using a second band-feed amount D2 in which the boundary portion 49 of the band 47 adjacent in the transport direction A does not overlap. It can be selected and executed.

Among these, in the first band feed recording mode 61, as shown in FIG. 5, the rear end of the first band 47A in which recording is first performed is the band feed recording of the second band 47B in which recording is performed next. When starting the first band feed amount D1 that coincides with the front end position of the second band 47B, the boundary 49 between the two adjacent bands 47A and 47B is overlapped.
In this embodiment, the band feed amount D1 is a length of a straight line connecting the centers of the nozzles 7a and 7n at both ends of the nozzle row 5.

Accordingly, the UV ink C1 is applied to the rear end of the first band 47A during the recording of the first band 47A, and the UV ink C1 is applied again as the front end of the second band 47B during the recording of the second band 47B. You will be beaten twice.
In FIG. 5, the recording head 15 originally does not move in the transport direction A. However, in order to make the explanation easier to understand, the arrangement of the nozzles 7 and the arrangement of the LEDs 41 at the time of the first recording of the band 47A performed earlier is described above. It is also shown as an afterimage at the position where the band feed amount D1 has moved.

Further, in this embodiment, the discharge and curing of the base UV ink C1 are continuously performed by one scan to the return path R of the recording head 15, and once to the forward path F of the recording head 15. In this scanning, the discharge and curing of the image forming UV ink C2 are continuously performed.
Specifically, as shown in FIG. 1, when the carriage 17 moves to the return path side R, the base ink C1 is ejected from the first recording head 15A, and the first UV light irradiation device 39A that follows this ejects the UV. Light (ultraviolet light) E is irradiated to cure the base ink C1 to form a base 11 serving as the first ink layer 51A on the recording surface 9 of the paper P.

  Further, as shown in FIG. 3, when the carriage 17 moves to the forward path side F, the image forming ink C2 is ejected from the second recording head 15B, and UV light ( The image forming ink C2 is cured by being irradiated with ultraviolet rays E, and the image 13 to be the second ink layer 51B is formed on the base 11 of the first ink layer 51A.

In the first band feed recording mode 61, the amount of the ink droplet C ejected to the boundary portion 49 between the first band 47A and the second band 47B that overlap is the first band 47A or the second time. Is set to be smaller than the amount of ink droplets C ejected to the intermediate portion 53 of the band 47B.
Specifically, the discharge amount of the ink C is divided into two stages, L and M, as an example, and M is set as an example with a size that is half of L.

In FIG. 5, the discharge amount of the base ink C1 from the nozzle 7a located in the front row and the nozzle 7n located in the last row of the nozzle row 5W of the first recording head 15A is set to M, and the nozzle row 5W is set. , 7n−1, the discharge amount of the base ink C1 from the nozzles 7b, 7c,.
Accordingly, the sum of the base ink C1 at the boundary portion 49 between the first band 47A and the second band 47B where the base ink C1 is hit twice is M + M = L, so that the first band 47A or the first band 47A. This is the same as the discharge amount L of the base ink C1 in the intermediate portion 53 of the second band 47B.

On the other hand, in the second recording head 15B, by setting the ejection amount of the image forming ink C2 ejected from the nozzle 7a located in the frontmost row of each nozzle row 5C, 5M, 5Y, 5K to 0, the paper When P is sent to the first band feed amount D1, the image forming ink C2 is not hit twice at the boundary portion 49 between the first band 47A and the second band 47B.
Accordingly, the discharge amounts of the image forming ink C2 of all the remaining nozzles 7b, 7c,..., 7n-1, 7n of the nozzle rows 5C, 5M, 5Y, and 5K of the second recording head 15B are all. L is set.

In the first band feed recording mode 61, the irradiation amount of the UV light (ultraviolet light) E applied to the boundary portion 49 between the overlapping first band 47A and the second band 47B is the first band. It is set to be smaller than the irradiation amount of UV light (ultraviolet rays) E irradiated to the intermediate portion 57 of 47A or the second band 47B.
Specifically, the irradiation amount of UV light (ultraviolet light) E is divided into two stages of L and M, which are the same as the discharge amount of the ink C, as an example. In FIG. 5, the LED of the first UV light irradiation device 39A When the irradiation amount of the UV light (ultraviolet light) E emitted from the LED 41a located in the front row and the LED 41n located in the last row of the row 55W is set to M so that the paper P is fed by the first band feed amount D1. The sum of the irradiation amounts of UV light (ultraviolet rays) E at the boundary portion 49 between the first band 47A and the second band 47B is M + M = L, and is intermediate between the first band 47A and the second band 47B. It becomes the same as the irradiation amount L of the UV light (ultraviolet light) E of the part 57.
The irradiation amounts of UV light (ultraviolet rays) E of all the LEDs 41a, 41b, 41c,..., 41n-1, 41n of the LED array 55C of the second UV light irradiation device 39B are all set to L. When recording the second band 47B, the irradiation amount of the LED 41a located in the front row is set to 0, so that when the paper P is fed by the first band feed amount D1, the first band 47A and the second band 47A are recorded. The UV light is not irradiated twice at the boundary of the band 47B.

Further, in the second band feed recording mode 62, as shown in FIG. 6, a second band feed amount D2 larger than the first band feed amount D1 where the boundary portion 49 between two adjacent bands 47A and 47B does not overlap is set. I use it.
Accordingly, the ink C that has been waiting at the boundary portion 49 of the band 47 in the first band-feed recording mode 61 is not double hit.
In FIG. 6, the recording head 15 originally does not move in the transport direction A, but the second band feed amount D2 is moved in the arrangement of the nozzles 7 and the arrangement of the LEDs 41 during the first recording of the band 47A. It is also shown as an afterimage at the position.

In the second band feed recording mode 62, the amount of the ink droplet C ejected to the boundary portion 49 between the two bands 47A and 47B is the amount of the ink droplet C ejected to the intermediate portion 53 of these bands 47A and 47B. It is set to the same amount as the amount.
Therefore, as shown in FIG. 6, the discharge amounts of the base ink C1 and the image forming ink C2 discharged from all the nozzles 7 of the first recording head 15A and the second recording head 15B are all set to L. Yes.

Similarly, in the second band feed recording mode 62, the irradiation amount of the UV light (ultraviolet light) E applied to the boundary portion 49 between the two bands 47A and 47B is set to be the first band 47A or the second band 47B. It is set to the same amount as the irradiation amount of UV light (ultraviolet rays) E irradiated to the intermediate portion 57.
Therefore, as shown in FIG. 6, the irradiation amounts of UV light (ultraviolet rays) E emitted from all the LEDs 41 of the first UV light irradiation device 39A and the second UV light irradiation device 39B are all set to L. .

Further, in the second band feed recording mode 62, the shift recording is performed in which the image 13 positioned at the boundary portion 49 of the band 47 is shifted by a predetermined shift amount O, the transport direction A, or the return direction opposite to the transport direction A. The mode 63 can be selected and executed.
That is, as shown in FIG. 7A, if there is an image 13 that is recorded at the boundary portion 49 of the band 47 if it is recorded as it is, if the shift recording mode 63 is selected, the image shown in FIG. As shown, the image 13 is recorded at a position shifted in the transport direction A or the return direction by a predetermined shift amount O, and the image quality of the image 13 is compared with the case where it is recorded at the position shown in FIG. Will improve.

Further, in the second band feed recording mode 62, when there is an image 13 straddling two adjacent bands 47A and 47B, the image 13 is rotated by a predetermined rotation angle θ, and any one of the bands 47A, 47A, The image rotation recording mode 64 within the width of 47B can be selected and executed.
That is, as shown in FIG. 8A, if there is an image 13 that would straddle two adjacent bands 47A and 47B if recorded as it is, if the image rotation recording mode 64 is selected, FIG. As shown in FIG. 8 (B), the image 13 is automatically rotated by a predetermined rotation angle θ and is recorded within the width of any one band 47A or 47B.
