Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a label sheet, and more particularly, to a method for producing a label sheet in which a back surface of a label substrate is printed.

2. Description of the Related Art In the related art, although various methods for producing a concealing label sheet are known, there is no known method for efficiently producing a concealing label sheet in which printing is performed on the back side of a concealing label base material.

The label to be peeled and formed from the concealing label sheet printed on the back side of the label base material, for example, the information to be concealed on a postcard or a card displaying the information to be concealed It is used to create a postcard or a card having concealing information that is peelably adhered so as to cover the concealing information, but if the information to be printed is to be concealed on the back side of the label base material, the concealing is performed. There is an advantage that the amount of information to be displayed can be increased.

For this reason, there is a demand for the development of an easy and efficient method for producing a concealed label sheet in which printing is performed on the back side of the label base material, and an object of the present invention is to meet this demand.

Means for Solving the Problems In order to achieve the above object, the present invention provides a continuous sheet in which two transparent sheets that are releasably bonded to each other are releasably bonded to a release sheet by an adhesive in one transparent sheet. A printing step in which information to be concealed on the surface of the transparent sheet opposite to the release sheet in the shape of the lower sheet is formed by reverse character printing, and a continuous state in which an adhesive is applied to the back side of the label base material for concealment In which the upper sheet is superimposed on the transparent sheet surface of the lower sheet on which reverse-character printing has been performed, and is adhered with the adhesive to conceal the concealment information on the transparent sheet surface.

The two transparent sheets that are releasably adhered to each other are attached to one of the transparent sheets so as to be releasably attached to the release sheet by an adhesive on the surface of the transparent sheet opposite to the release sheet of the continuous lower sheet. While performing reverse letter printing, a continuous upper sheet with an adhesive applied to the back side of the concealing label base material is superimposed on the reverse sheet-transparent transparent sheet surface of the lower sheet, and the adhesive is applied. By this, a concealed label sheet in which printing is performed on the back surface of the label base material is created.

Embodiments Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Here, FIG. 1 is an explanatory view schematically showing a preparation process, FIG. 2 is a sectional view of a lower sheet, FIG. 3 is a sectional view of an upper sheet, and FIG. 4 is a view of a bonded upper sheet and a lower sheet. FIG. 5 is a cross-sectional view showing a state before the die removing step, FIG. 5 is a sectional view showing a state after the die removing step, FIG. 6 is a plan view of the same state, and FIG. FIG. 8 is a cross-sectional view showing a state in which unnecessary portions other than labels are similarly peeled from the release sheet, FIG. 9 is a plan view of the same state, and FIG. 10 is a partially peeled label attached to a postcard. FIG. 11 is a cross-sectional view showing another configuration of the concealing label sheet to be created.

As shown in FIGS. 1 and 2, a transparent polyethylene film 2 as a transparent sheet is releasably adhered to a release sheet 1 by an adhesive 3, and the transparent polyethylene film 2 is provided on the side opposite to the release sheet 1. A continuous lower sheet 6 in which a transparent polypropylene film 4 as a transparent sheet is releasably bonded via a transparent polypropylene layer 5 is wound around a roll 7 with the transparent polypropylene film 4 positioned on the front side. ing. The lower sheet 6 is pulled out via a guide roll,
Information X to be transferred rightward in FIG. 1 by a suitable transfer mechanism (not shown) and to be concealed by the printing device 8 on the transparent polypropylene film 4 surface, for example, a description of the expiration date of the time deposit (see FIG. 4). Is subjected to a printing process of reverse character printing. By performing reverse character printing in this manner, the information X to be concealed can be visually recognized as regular characters when viewed from the release sheet 1 side.

As shown in FIGS. 1 and 3, an aluminum foil 10 for improving opacity is integrally provided on the back side of the concealing label base material 9, and the label base material of the aluminum foil 10 is provided. A pressure-sensitive adhesive 11 is applied to the side opposite to 9 and a release sheet.
A continuous upper sheet 13 coated with the adhesive 11 with 12
However, when the release sheet 12 is positioned on the front side,
It is wound around 14. The upper sheet 13 is pulled out via a guide roll, and in the process of reaching the guide roll, the release sheet 12 is peeled off by the release cylinder 15 and the adhesive 11
In a state where the adhesive 11 is facing the transparent polypropylene film 4 side of the lower sheet 6 in a state where the lower sheet 6 is exposed, the lower sheet 6 is transferred rightward in FIG. 1 by an appropriate transfer mechanism (not shown).

Then, as shown in FIG. 1, the upper sheet 13 and the lower sheet 6 are transported in an overlapping manner, and a pair of upper and lower pressing rollers 16 are provided.
By applying appropriate pressure from above and below,
On the transparent polypropylene film 4 surface of the lower sheet 6, a superposition bonding step of bonding the upper sheet 13 with the adhesive 11 is performed (see FIG. 4). Here, the concealment label sheet 21 is created.

As shown in FIG. 1, the concealing label sheet 21 composed of the upper sheet 13 and the lower sheet 6 in a continuous state adhered by the above-mentioned laminating step is opposed to the surface side of the label base 9 of the upper sheet 13. Next, a table printing step of printing the normal display information Y, for example, the title of the “time deposit maturity notification”, the display of the sender's bank name, and a cautionary statement indicating the peeling start position by the printing device 17 is performed. State.

Subsequently, as shown in FIG. 1, FIG. 5 and FIG. 6, the contour of the label is formed on the concealed label sheet 21 in the above-mentioned continuous state except for the release sheet 1 by the die cutting device 18. A die-cutting step is performed in which a substantially square-shaped cut 19 having rounded corners is made and die-cutting is performed. In this die-cutting step, two parallel perforations 20 for specifying a peeling position are also provided for the transparent polypropylene film 4 of the upper sheet 13 and the lower sheet 6.

Further, as shown in FIGS. 1 and 7, a marginal hole 23 penetrating from the label base material 9 to the release sheet 1 is formed in the continuous continuous concealing label sheet 21 by the marginal punch device 22 in the width direction. It is located on both sides and is provided at equal intervals in the continuous direction. Further, the unnecessary portion is peeled off from the release sheet 1 by winding the outer portion of the cut 19 into the release cylinder 24, and as shown in FIGS. 8 and 9, the release sheet 1 having the marginal holes 23 is provided. Then, a continuous label sheet 26 to which labels 25 are peelably adhered at predetermined intervals in the longitudinal direction is created. Further, the transported continuous label paper 26 is sequentially wound on a winding roll 27 as shown in FIG.

The continuous label paper 26 thus produced is peeled off the label 25 from the release sheet 1, as shown in FIG. 10, by the adhesive 3 exposed on the postcard 30 or the desired information display surface of the card. Can be glued. Thus, the information Z on the information display surface is covered and concealed by the label 25. When the label 25 is peeled from the release sheet 1, the information X to be concealed, which is reversely printed on the transparent polypropylene film 4 of the label 25, is printed.
Is a transparent polypropylene film 4 and a transparent polyethylene film 2 which is quasi-bonded releasably thereto.
In a protected state. And the label 25
Is separated from the portion of the transparent polypropylene layer 5 so as to be peeled off with the transparent polyethylene film 2 left on the postcard 30 or card that has been adhered. (See Figure 10). In the peeled state, the information Z of the postcard 30 and the card which have been concealed can be visually recognized through the transparent polyethylene film 2, while the information X to be concealed of the label 25 can be visually recognized through the transparent polypropylene film 4. is there.

Note that the present invention is not limited to the above-described embodiment. For example, instead of the aluminum foil 10, printing may be performed on the back surface of the label base material 9 to enhance the opacity. If the opaque property of the label base material 9 itself is sufficiently high, it is not necessary to perform these processes. Furthermore, the timing of performing the front printing step may be any time before the die cutting step, and may be before the overlapping bonding step or before the printing step for printing reverse characters. Furthermore, in the printing step of printing the reverse character, it is possible to repeatedly perform predetermined printing in addition to performing predetermined printing at regular intervals. Further, the transparent polypropylene film 4, the transparent polypropylene layer 5, or the transparent polyethylene film 2
Other synthetic resins may be used. Further, the continuous label paper 26 can be folded using a folding device instead of the take-up roll 27, or can be formed into a single piece using a cutting device. In addition, if the index indicating the drilling position and the table printing position of the marginal hole 23 is printed simultaneously with the reverse character printing, matching between the reverse character printing position and the drilling position and the table printing position of the marginal hole 23 is easy. is there. Further, in the present invention, as shown in FIG. 11, a label base material 31 for concealment is extended through a perforation 32, and the extended portion is configured as a postcard piece or a card piece.
It is also possible to produce a concealed label sheet 35 having a configuration in which the release paper 33 is peeled off from the slit 34 and folded at the perforations 32 to form a postcard or a card. Furthermore, the upper sheet 13 and the lower sheet 6 are not only continuous,
A single piece can also be used.

Effects As apparent from the above description, according to the present invention, a label sheet can be easily and efficiently created, and the label created by the present method is peeled off from the release sheet together with the transparent sheet of the lower sheet, The reverse character printing that is the information to be concealed applied to the back side of the label base material for concealment is peeled off from the release sheet in a state protected by the transparent sheet, and from the postcard etc. adhered even when using the label, Since it is peeled off with the transparent sheet,
This has the effect that the information to be concealed, which is printed in reverse characters, is always protected.
