It is a figure which showed the other structural example of a beverage can.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a perspective view of a beverage can 100 according to the present embodiment.
Here, in FIG. 1, the detailed shape of the beverage can 100 is not shown, and is represented by a bottomed cylinder. More specifically, the beverage can 100 is generally provided with a flange portion and a neck portion, and the bottom of the beverage can 100 is generally a circle recessed inward of the beverage can 100. However, these illustrations are omitted.

The beverage can 100 of the present embodiment is provided with a can body 200 formed in a cylindrical shape.
A circular opening 210 is formed in the upper part of the can body 200. Further, a bottom portion 220 is provided at the lower portion of the can body 200. Further, the can body 200 includes an outer peripheral surface 230.
The outer peripheral surface 230 is printed by an inkjet head, and the outer peripheral surface 230 is provided with a printed image formed in a strip shape along the circumferential direction of the can body 200.
In the present embodiment, the inside of the can body 200 is filled with the beverage as the content through the opening 210 located at the upper part of the can body 200. After that, the opening 210 is closed by a can lid (not shown). This completes the beverage can filled with the beverage.

The can body 200 is made of a metal material. Specifically, the can body 200 is formed of, for example, aluminum, an aluminum alloy, or the like. Further, the can body 200 is formed of, for example, an iron alloy such as tin-free steel.
Further, the can body 200 is formed, for example, by drawing and ironing (DI) forming or stretch drawing forming a flat plate.
Examples of the beverage filled inside the can body 200 include alcoholic beverages such as beer and non-alcoholic beverages such as soft drinks.

FIG. 2 is a perspective view of the printing apparatus 500.
The printing apparatus 500 of the present embodiment is provided with a cylindrical support member (mandrel) 600 that is inserted into the beverage can 100 and supports the beverage can 100.
The support member 600 is formed in a cylindrical shape and is inserted into the beverage can 100 through the opening 210 (see FIG. 1) of the beverage can 100. Then, in the present embodiment, the support member 600 is rotated in the circumferential direction by a drive mechanism (not shown), and the beverage can 100 is also rotated in the circumferential direction accordingly.

An inkjet head 400 is provided above the beverage can 100. The bottom of the inkjet head 400 is provided with a plurality of ink ejection ports 610 arranged along the axial direction of the beverage can 100 supported by the support member 600.
Further, the printing apparatus 500 of the present embodiment is provided with a printing control unit 510 that controls the ejection of ink in the inkjet head 400. The print control unit 510 is composed of a program-controlled CPU (Central Processing Unit). Here, reference numeral 2X in FIG. 2 is an enlarged view of the ink ejection port 610 used for printing the portion indicated by reference numeral 1X in FIG.
In the present embodiment, the inkjet head 400 is controlled by the print control unit 510, and ink is ejected from the ink ejection port 610 to the outer peripheral surface of the beverage can 100 located downward and rotating in the circumferential direction. As a result, a printed image is formed on the outer peripheral surface of the beverage can 100.
Here, FIG. 2 is an example of printing with an inkjet head 400 of one color, and the inkjet head 400 of a required color sequentially prints according to the same printing method to form a final image. More specifically, for example, a four-color inkjet head 400 of CMYK is prepared, and printing is sequentially performed according to the same printing method using the inkjet head 400 of each color to obtain a final image. Here, printing is performed in the order of, for example, cyan (C), magenta (M), yellow (Y), and black (K).

When printing on the beverage can 100 by the inkjet head 400, the peripheral speed of the beverage can 100 is preferably 10 to 73 m / min (10 m / min ≤ peripheral speed ≤ 73 m / min).
If the peripheral speed is less than 10 m / min, the productivity will deteriorate. Further, when the peripheral speed exceeds 73 m / min, the ink ejection from the inkjet head 400 cannot catch up, and the intervals between the dots constituting the printed image are widened. Further, if the peripheral speed exceeds 73 m / min, an air flow may be generated between the inkjet head 400 and the beverage can 100, and the ink adhesion position may shift.
A more preferable range of the peripheral speed of the beverage can 100 is 25 to 60 m / min. In this case, it is easy to suppress the deterioration of productivity and the deterioration of image quality at the same time.

3 (A) and 3 (B) and FIGS. 4 (A) and 4 (B) are developed views of printed images formed on the outer peripheral surface 230 of the beverage can 100.
In the present embodiment, as described above, the printed image is formed by so-called inkjet printing. This printed image extends along the circumferential direction of the beverage can 100 and is formed in a band shape.
Specifically, printing on the beverage can 100 is performed by rotating the beverage can 100 in the circumferential direction and from the inkjet head 400 extending along the axial direction of the beverage can 100 to the outer peripheral surface 230 of the beverage can 100. Ink is ejected toward. As a result, a printed image extending along the circumferential direction of the beverage can 100 is formed on the outer peripheral surface 230 of the beverage can 100.

In the printed image shown in FIG. 3A, the portion indicated by reference numeral 3A is the printing start position. At the time of printing, ink ejection is started at this printing start point (hereinafter referred to as “printing start point 3A”), and printing is sequentially performed toward the right direction in FIG. 3 (A). Then, the ink ejection is stopped at the printing end portion 3B, and the printing is terminated.

Here, in printing using the inkjet head 400, the amount of ink ejected at the start of printing tends to be larger than the amount of ink ejected after the start of printing, and the image formed at the start of printing is the other portion. It may be more noticeable than the image.
More specifically, the dot image formed at the start of printing may be larger than the dot image formed later, and the image formed at the start of printing may become conspicuous.

In particular, as in the present embodiment, when the beverage can 100 is arranged and ink is simultaneously ejected from the ejection port of the required portion by one linear start line along the axial direction, it is formed at the start of printing. The resulting image becomes a vertical streak image, and this vertical streak image may become conspicuous.
Therefore, in the present embodiment, when the ink ejection to the outer peripheral surface 230 of the beverage can 100 is started, the ink ejection timing is partially shifted, and the image formed by the ink ejected at the start of printing is obtained. It suppresses the fact that it stands out.

Specifically, in the printing apparatus 500 of the present embodiment, when starting to eject ink to the outer peripheral surface 230, the ejection timing of ejecting ink from one group of ink ejection ports 610 and the ejection timing of this one group of ink. The timing of ejecting ink from the ink ejection port 610 of another group different from the ejection port 610 is deviated.
More specifically, in the present embodiment, when starting to eject ink to the outer peripheral surface 230 of the beverage can 100, for example, the ink ejection port 610 (a group of ink ejection) represented by reference numeral 2A in FIG. 2 The ink is ejected from the outlet 610) first, and then the ink is ejected from the ink ejection port 610 (another group of ink ejection ports 610) indicated by the reference numeral 2B in FIG. 2 after the reference numeral 2C described later. conduct.

As a result, in the present embodiment, as shown by reference numerals 3E and 3F in FIG. 3A, the two linear images formed at the start of printing are displaced in the circumferential direction of the beverage can 100.
More specifically, in the present embodiment, the ink is first ejected from the ink ejection port 610 (hereinafter referred to as "starter ink ejection port group 610A") indicated by reference numeral 2A in FIG. 2, and then FIG. 2 By ejecting ink from the ink ejection port indicated by reference numeral 2B (hereinafter, “sequential ink ejection port group 610B”) (after reference numeral 2C described later, ink is ejected from the subsequent ink ejection port group 610B). In), as shown by reference numerals 3E and 3F in FIG. 3A, the positions of the two linear images formed at the start of printing are shifted in the circumferential direction of the beverage can 100.
In other words, in the present embodiment, when starting to eject ink to the outer peripheral surface 230, the ink ejected from one group of ink ejection ports 610 (starter ink ejection port group 610A) adheres to the outer peripheral surface 230. The adhesion position and the adhesion position where the ink ejected from the ink ejection port 610 of another group (subsequent ink ejection port group 610B) adheres on the outer peripheral surface 230 are different from each other in the circumferential direction of the beverage can 100. Controls ink ejection.
Further, in the present embodiment, after ink is ejected from each of the ink ejection ports 610 included in one group of ink ejection ports 610 (starter ink ejection port group 610A) at the same timing, ink ejection of another group is performed. Ink is ejected from each of the ink ejection ports 610 included in the outlet 610 (later ink ejection port group 610B) at the same timing.

As a result, the linear image indicated by reference numeral 3E in FIG. 3A is first formed, and then the linear image indicated by reference numeral 3F in FIG. 3A is formed (reference numeral 2C in FIG. 2 to be described later). After the formation of the image connecting the reference numerals 3E and 3F formed by the above, the linear image indicated by the reference numeral 3F is formed), and the positions of the two linear images are displaced in the circumferential direction of the beverage can 100.
In this case, dots having a large diameter are suppressed from being aligned linearly along the axial direction of the beverage can 100, and the image formed by the ink ejected at the start of printing becomes inconspicuous.

Explaining with reference to FIG. 1, in the present embodiment, as a result of shifting the ejection timing of the ink, the image 1A (located on the left side in the figure with respect to the broken line 1C of the waveform) formed at the start of printing among the printed images An image located on the right side of the figure from the joint 1E (described later) (hereinafter referred to as "printing start image 1A") and an image 1B formed at the end of printing (on the right side of the figure from the broken line 1D of the waveform). The joint (connecting line) 1E with the position (the image located on the left side of the joint 1E in the figure) (hereinafter referred to as “printing end image 1B”) is along the axial direction of the beverage can 100. It is not a straight line, and the position of a part of the joint portion 1E is displaced in the circumferential direction of the beverage can 100.

More specifically, in the present embodiment, the joint portion 1E has a corrugated shape (the joint portion 1E has a shape in which a convex shape (convex portion) and a concave shape (concave portion) are alternately arranged in the axial direction of the can body 200. Next), at a plurality of joint portions 1E, a part of the joint portion 1E is displaced in the circumferential direction of the beverage can 100.
Then, in this case, the joint portion 1E becomes less noticeable as compared with the case where the joint portion 1E is a straight line along the axial direction of the beverage can 100.
Further, in the print start portion 3A and the print end portion 3B shown in FIG. 3A, ink is ejected from the ejection port at the position corresponding to the image, and the area without the image (print start portion 3A, print end portion 3B) is discharged. Printing is performed at the printing start point 3A and the printing end point 3B so that the ink is not ejected from the ejection port corresponding to each of the blank areas located in each of the above, except for the printing start point 3A and the printing end point 3B. By ejecting ink from the ejection port corresponding to the printed image and printing at the location, the joint portion (connecting line) 1E in FIG. 1 is prevented from becoming a single straight line along the axial direction of the beverage can 100. become.

Further, in the present embodiment, as shown by reference numeral 1H in FIG. 1, a part of the joint portion 1E is inclined with respect to the axial direction and the circumferential direction of the beverage can 100, and a part of the joint portion 1E is oblique. It is a line.
Here, for example, a part of the joint portion 1E can be along the circumferential direction of the beverage can 100 as shown by the broken line 1G in the figure, but in this case, a horizontal streak-shaped image appears in the printed image. It will be easier. If the diagonal line is used as in the present embodiment, the generation of this horizontal streak-shaped image can be suppressed.

The diagonal line is formed by ejecting ink from a plurality of ink ejection ports 610 shown by reference numeral 2C in FIG.
Specifically, the diagonal line is ink from a plurality of ink ejection ports 610 (hereinafter referred to as "intermediate ink ejection port group 610C") located between the starting ink ejection port group 610A and the late ink ejection port group 610B. Is formed by discharging.
More specifically, after the ink is ejected from the original ink ejection port group 610A and before the ink is ejected from the late ink ejection port group 610B, the ink is discharged from the intermediate ink ejection port group 610C. Discharge and form a diagonal line.

More specifically, when the ink is ejected from the intermediate ink ejection port group 610C, the ink ejection port 610 included in the intermediate ink ejection port group 610C is located closer to the starting ink ejection port group 610A. The ink is ejected from the ink ejection port 610 first, and then the ink is ejected from the ink ejection port 610 located closer to the subsequent ink ejection port group 610B.
More specifically, when ejecting ink from the intermediate ink ejection port group 610C, the ink ejection port 610 located closer to the starting ink ejection port group 610A among the ink ejection ports 610 included in the intermediate ink ejection port group 610C. Then, the ink is ejected in order, and finally, the ink is ejected from the ink ejection port 610 close to the subsequent ink ejection port group 610B. As a result, as described above, a part of the joint portion 1E becomes an oblique line.

The printed image formed on the outer peripheral surface 230 of the beverage can 100 is performed based on the image data prepared in advance. More specifically, computer software is used to generate image data in which the joint portion 1E becomes a waveform, and a printed image is formed based on the generated image data.
More specifically, in the generation of the image data in which the joint portion 1E becomes a waveform, for example, a part of the image data of the portion corresponding to the printing start portion 3A (see FIG. 3A) is cut out and cut out. The image data is pasted next to the image data of the portion corresponding to the print end portion 3B (see FIG. 3A).

In other words, a part of the image data corresponding to the printed image formed at the start of printing is moved in parallel to the side of the image data corresponding to the printed image formed at the end of printing and pasted, and a new image used for printing is used. Generate data.
Then, the newly generated image data is supplied to the print control unit 510 provided in the printing apparatus 500 (see FIG. 2). The print control unit 510 performs predetermined image processing on the image data. Specifically, a color separation process is performed, and then the density of each color is adjusted.
Then, the print control unit 510 controls the inkjet head 400 based on the image data after the color separation processing and the density adjustment, and forms a print image on the outer peripheral surface 230 of the beverage can 100.

Here, the length L of the joint portion 1E (see FIG. 1) (the length of the joint portion 1E when the joint portion 1E is projected in the axial direction of the beverage can 100 (the length in the circumferential direction of the beverage can 100). ) Is preferably 5 to 30 mm when the diameter of the beverage can 100 is 35 to 80 mm and the height (length in the axial direction) is 60 to 180 mm. In this case, it is easy to process the image when the image data is newly formed as described above, and the influence on the printed image is small.

Further, if the joint portion 1E is corrugated, the beverage can 100 needs to be rotated more than one rotation at the time of printing, but if the length L of the joint portion 1E is 5 to 30 mm, the portion exceeding one rotation is required. The amount of rotation is small. The more preferable length L of the joint portion 1E is 8 to 25 mm.
The smaller the diameter of the beverage can 100, the smaller the peripheral length of the beverage can 100, and the proportion occupied by the joint portion 1E increases relatively. Therefore, when the diameter of the beverage can 100 is small, the length L It is preferable to adopt a smaller value within the range of 5 to 30 mm.

Further, in the present embodiment, as described above, a part of the image data corresponding to the printed image formed at the start of printing is cut out, and the part of the image data corresponds to the printed image formed at the end of printing. Although it is pasted next to the image data, the place where the image data is cut is not particularly limited.
Further, the number of places where the image is cut is not particularly limited. In the example shown in FIG. 3A, the image data is cut at three points, but it may be any of 1 to 15 points, for example.
The height of a normal beverage can 100 is 60 to 180 mm, and in this case, image data can be cut out at, for example, 1 to 15 points. More preferably, it is 2 to 5 places.

Further, the cut shape which is the shape when cutting the image data is not particularly limited, and may be, for example, a quadrangle, a triangle, a trapezoid, or a semicircle.
When the cut shape is triangular, trapezoidal, or semi-circular, an oblique line is formed at the joint portion 1E as described above.
Further, when the image data is cut at a plurality of places, the cut shape at each cut place may be the same, or may be different as shown in FIG. 5 (a figure showing another example of the printed image). good. When they are different, the corrugated shape does not have periodicity, and the joint portion 1E becomes less noticeable than having periodicity.

Other examples of the printed image will be described with reference to FIGS. 3 (B), 4 (A), and (B).
In the example shown in FIG. 3B, the cut shape is a triangle. In this case, the joint portion 1E is formed only by diagonal lines, and the joint portion 1E does not include straight lines along the circumferential direction and the axial direction of the beverage can 100, so that the joint portion 1E becomes more inconspicuous. ..
In the example shown in FIG. 4A, the cut shape is a substantially semicircular shape. In this case as well, straight lines along the circumferential direction and the axial direction of the beverage can 100 are hardly provided, and the joint portion 1E becomes inconspicuous.

In the example shown in FIG. 4B, the cut shape is trapezoidal. More specifically, the lower base having a large side length is located near the printing end point indicated by reference numeral 4F, and the upper base having a small side length is located near the printing start point indicated by reference numeral 4E. Is located in.
In this configuration example, when printing the portion indicated by reference numeral 4H, printing is first performed at the portion indicated by reference numeral 4X, then ink ejection is temporarily interrupted, and then printing is performed again from the portion indicated by reference numeral 4Y. Will be printed.

That is, in this configuration example, the first ink ejection, the ink ejection stop, and the second ink ejection are performed at a specific portion. Here, in this case, as in the above case, the diameter of the dots constituting the printed image becomes large at the time of the second ink ejection, and the image formed at the time of the second ink ejection may become conspicuous.
Therefore, it is preferable that the shape of the printed image is such that the ink ejection is not interrupted in the middle even in the cut and pasted image. In other words, it is preferable to have a shape that does not perform intermittent operation even for a short time. In the examples shown in FIGS. 3 (A), 3 (B), 4 (A), and 5 above, the ink ejection is not interrupted in the middle, and the ink ejection continues from the start of printing to the end of printing. It is done.

In the configuration examples shown in FIGS. 3 (A), (B), 4 (A), (B), and 5, the lower portion of the printed image in the figure has a white background, and further. A character image is formed in the lower part.
When the printed image contains a white background in this way, the joint portion 1E becomes inconspicuous.
Further, if the joint portion 1E is provided at the portion where the character image is formed, there is a concern that the character image may be difficult to see, but in printing using the inkjet head 400, it is possible to print with high accuracy. , It is prevented that the character image becomes difficult to see.
Further, in the above, the case where a part of the joint portion 1E is made an oblique line has been described as an example, but as shown in FIG. 6 (a diagram showing another configuration example of the beverage can 100), the joint portion 1E All may be diagonal lines.
