Description

  The present invention relates to an elongated decorative raw fabric whose design is repeatedly represented in the lengthwise direction, and a method for producing a long decorative sheet which is a divided product of the elongated decorative raw fabric.

Generally, a decorative sheet such as a label, a packaging material, a wrapping ribbon, etc. is obtained by cutting a long strip-shaped original fabric decorated by design printing.
Such a web typically has a long strip-like web and a plurality of design printing units repeatedly printed in the lengthwise direction of the web. A long decorative sheet is obtained by cutting this long decorative raw fabric along the length direction.
Specifically, a label used by being attached to a container or the like will be described as an example.
In order to obtain a label, a long decorative original fabric is printed by repeatedly printing a design printing portion representing an arbitrary design in the lengthwise direction of the web, and a row of the design printing portions repeated in this lengthwise direction is in the width direction More than one is placed. In order to divide this original fabric into rows of design printing units, an elongated decorative sheet in which one design printing unit is repeated in the longitudinal direction is obtained by cutting the original fabric along the length direction. Be One label is obtained by cutting this long decorative sheet into one design printing unit.

The step of dividing the long decorative raw fabric into rows is called slitting (also called slitting), and a cutter or the like placed in the middle of the transportation of the long decorative raw fabric transported in the lengthwise direction. The long decorative original fabric is cut along the length direction by the cutting means.
By the way, when a long decoration original fabric is conveyed to a line by making a length direction into a conveyance direction, a long decoration original fabric may be position-shifted (streaking) in the width direction. If the slit processing is performed in a meandering state, cutting can not be performed at a predetermined position (hereinafter referred to as a planned position). Therefore, the correction system which corrects a meander of a long decoration original fabric is used. The correction system includes a reference line printed on the web of the long decorative original fabric and extending in the longitudinal direction of the web, and a detector for detecting the reference line disposed in the middle of the transport line. And a control unit that corrects the meandering of the original fabric by adjusting the direction of the transport roller and the like based on the detection result of the detector. By constantly reading the reference line with the detector, the meandering of the long decorative original fabric is corrected, and it becomes possible to cut at a predetermined position over the entire length direction.

In the long decorative original fabric for obtaining the label, the design printing unit and the reference line are often printed by a gravure printing method using a gravure plate cylinder.
In this respect, the present inventors manufactured a long decorative original fabric printed by the flexographic printing method on the design printing portion, the reference line and the like, but the long decorative original fabric printed by the flexographic printing method is scheduled It has been found that there is a risk of slitting in a state of being displaced from the position.

A first object of the present invention is to provide a long decorative original fabric which is easy to correct meandering during slit processing.
A second object of the present invention is to provide a method of manufacturing an elongated decorative sheet which can be cut at a predetermined position over the entire length direction.

The present inventors diligently studied the above-mentioned concerns.
The flexographic printing method is a method of printing flexographic ink using a cylindrical plate having a cylindrical plate cylinder and a sheet-like printing plate wound around the plate cylinder. In the case of a cylindrical plate used in a printing method such as flexographic printing method or letterpress rotary printing method, when a sheet-like printing plate is wound around a printing cylinder, one end of the printing plate and its edge A seam is created where the opposite ends meet. Such seams do not have a printing plate (no ink), and ink can not be printed on the web at locations corresponding to the seams of the cylindrical plates. Therefore, when the reference line is printed by a printing method using a cylindrical plate in which a sheet-like printing plate such as flexographic printing method or letterpress rotary printing method is wound around a printing cylinder, in a portion corresponding to the joint portion of the cylindrical plate The reference line is cut off and printed. As described above, when the reference line is interrupted in the length direction, the detector disposed on the transport line can not partially read the reference line, and there is a possibility that the positional deviation of the original fabric can not be corrected with high accuracy. The inventors have identified that there is.
In addition, since the present gravure printing method uses the gravure plate cylinder which formed the cell which stores an ink directly in a cylinder, the break of the reference line by printing methods, such as the said flexographic printing method, does not arise. The present inventors have found that the above-mentioned concern is unique to the printing method using a cylindrical plate obtained by winding a sheet-like printing plate around a plate cylinder, and completed the present invention.

  The elongated decorative raw fabric according to the present invention is a strip-shaped web, a printing unit representing an arbitrary design, and a plurality of design printing units repeatedly printed in the lengthwise direction of the web, and the web A reference line printing portion printed in the lengthwise direction, the design printing portion comprising a first design portion formed from the first ink and a second design portion formed from the second ink A plurality of first ink printing units, wherein the reference line printing unit is a first ink printing unit formed of the same ink as the first design unit, and is intermittently formed in the longitudinal direction of the web And a second ink printing portion formed of the same ink as the second design portion, wherein the second ink printing portion is formed in a first ink absence portion generated between the first ink printing portion; And the reference line printing unit is configured to print the first ink When formed in a continuous line shape extending in a longitudinal direction of the web by second ink printing unit.

In a preferable long decorative source sheet of the present invention, the second ink printed portion is intermittently formed in the lengthwise direction of the web, and a second ink absent portion generated between the second ink printed portions. The first ink printing unit is formed.
In a preferred long decorative source sheet of the present invention, the first design part and the second design part and the first ink printing part and the second ink printing part are formed by letterpress printing.

According to another aspect of the present invention, a method of manufacturing a long decorative sheet is provided.
In the method of manufacturing a long decorative sheet according to the present invention, a process of conveying any of the long decorative original fabric in the length direction, a reference line of the long decorative original fabric being conveyed is detected by a detector, And correcting the positional deviation in the width direction of the raw fabric being transported, and cutting the long decorative original fabric along the length direction.

  The long decorative raw fabric of the present invention is easy to correct meandering at the time of slitting, and by using such a raw fabric, it is possible to easily manufacture a long decorative sheet cut at a predetermined position over the entire length direction. Can.

By mounting, as shown in FIG. 10, a second cylindrical plate 82 having a second printing plate 821 is obtained. The seam 824 of the second cylindrical plate 82 corresponds to both ends of the second printing plate 821 and the joint adhesive, and the seam 824 has no relief.
The first printing plate 811 shown in FIG. 8 is also attached to the plate cylinder 812 in the same manner as in FIG. 9, thereby providing a first cylinder having a seam 814 and having the first printing plate 811 as shown in FIG. A plate 81 is obtained.
Further, the third printing plate 831 on which the letterpress printing plate for printing the third design portion 53 is formed is also mounted on the plate cylinder 832 in the same manner as in FIG. A third cylindrical plate 83 is obtained. Also for the first cylindrical plate 81 and the third cylindrical plate 83, their seams 814, 834 have no printing plate (part for printing ink).

  FIG. 11 is a plan view showing the process of printing on the web 2 using the cylindrical plate 8. This plan view is also a view of the back side of the web 2 from the outside of the center drum 71 of FIG. Note that FIG. 11 is a plan view seen from the back side of the web 2, so that the printing unit such as the design printing unit appears opposite to the plan view seen from the front side of the web 2 as shown in FIG. Please note.

Referring also to FIG. 11, the first ink is printed on the back surface of the web 2 by the first cylindrical plate 81 to form a first design portion 51 and a first ink printing portion 61. The first ink printing unit 61 is formed in a linear shape elongated in the longitudinal direction of the web 2, but the first ink is not printed on the web 2 corresponding to the joint 814 of the first cylindrical plate 81. A portion corresponding to this joint is the first ink non-existence portion 6a.
Next, the second ink is printed on the back surface of the web 2 by the second cylindrical plate 82 to form a second design portion 52 and a second ink printing portion 62. The second ink printing unit 62 is formed in a linear shape elongated in the longitudinal direction of the web 2, and the relief plate of the second cylindrical plate 82 for printing the second ink printing unit 62 is the first ink absence portion. The second cylindrical plate 82 is set so as to overlap 6a. For this reason, the second ink printing unit 62 is formed in the first ink absence portion 6a.
Although the second ink is not printed at the location corresponding to the joint 824 of the second cylindrical plate 82 (that is, it becomes the second ink absent portion 6b), the second ink absent portion 6b is , And the first ink printing unit 61 has already been printed.
Finally, the third ink is printed on the back surface of the web 2 by the third cylindrical plate 83 to form the third design portion 53, whereby the long decorative original fabric 1 is obtained. Depending on the type of ink, the ink may be dried or irradiated with ionizing radiation such as ultraviolet light to cure each ink.
The obtained long decorative original fabric 1 is usually wound around a core material 79 as shown in FIG. 7 and provided for storage and transportation.

<Method for producing long decorative sheet>
The said long decoration sheet is obtained by cut | disconnecting the said long decoration original fabric 1 along a length direction.
That is, in the method of manufacturing the long decorative sheet, the step of conveying the long decorative original fabric 1 in the length direction, the reference line 4 of the long decorative original fabric 1 being conveyed is detected by the detector, Correcting the displacement in the width direction of the original fabric, and cutting the long decorative original fabric 1 along the length direction.

Specifically, the long decorative raw fabric 1 wound in a roll shape is drawn out in the lengthwise direction and conveyed into the production line. As shown in FIG. 12, a detector 75 is disposed in the middle of conveyance in the longitudinal direction. The detector 75 detects the reference line 4 represented by the reference line printing unit 6. Although the detector 75 is usually disposed on the front surface side of the web, it may be disposed on the back surface side or may be disposed on both the front surface and the back surface.
Since the long decoration original fabric 1 has a long shape in which the length direction is sufficiently long, it may be misaligned in the width direction during the conveyance. That is, the long decorative original fabric 1 meanders in the width direction during conveyance. When the reference line 4 is displaced in the width direction along with the meandering of the long decorative original fabric 1, the detector 75 detects the deviation, and adjusts the direction of the transport roller of the manufacturing line based on the detection result, The meandering of the decorative original fabric 1 is corrected. Such correction is preprogrammed by a control unit (not shown).

On the downstream side of the detector 75, a cutter 76 for slitting the long decorative original fabric 1 is disposed. As the cutting machine 76, a cutter, a laser cutting machine and the like can be mentioned besides a slitter having a scaly blade 77 as shown.
In addition, the system and cutting machine which correct | amend the meandering of original fabric, such as a detector and a control part, can use the thing of a conventionally well-known manufacturing line suitably.
The long decoration original fabric 1 is cut along the length direction by the cutting machine 76. Usually, as shown in FIG. 12, it cuts along the length direction between adjacent lines so that the long decoration original fabric 1 may be divided into lines. However, the present invention is not limited to the case where cutting is performed so as to be divided into one column as described above, and division may be performed into a plurality of columns such as 2 columns or 3 columns.
Note that one side including the reference line printing unit 6 and the opposite side are portions that do not have the design printing unit 5 and are discarded at the time of slitting.
Thus, a long decorative sheet 10 as shown in FIG. 13 is obtained. In the long decorative sheet 10, the design print unit 5 of one design pattern is repeatedly printed in the longitudinal direction of the long strip-like web 2.

The reference line printing section 6 of the long decorative original fabric 1 of the present invention has the second ink printing section 62 formed in the first ink absence section 6 a generated between the first ink printing sections 61, so that the reference line The printing unit 6 is formed in a continuous line in the longitudinal direction of the web 2. Therefore, the reference line 4 is not interrupted in the longitudinal direction, and the reading error of the reference line 4 by the detector 75 can be prevented. Therefore, it is easy to correct the meandering of the long decorative original fabric 1, and it is possible to obtain the long decorative sheet 10 cut at a predetermined position over the entire length direction.
Generally, when the reference line is printed by a printing method using a cylindrical plate having a sheet-like printing plate such as flexographic printing, it is partially interrupted, but in the present invention, the first ink is printed by the printing method Then, the second ink is printed on the interrupted portion to complement that portion, and the concerns of the printing method can be solved.
