However, the conventional label manufacturing method is a method of printing a desired design on the surface 1a of the base paper 1 by letterpress printing. Sometimes it was slightly different from what was intended. In particular, it is remarkable in white solid printing or gold-silver printing, and has been a problem.

[0006] In order to solve this problem, in the case of a design with gold and silver printing, foil stamping is performed. However, when performing foil stamping, it takes time and effort and the production efficiency deteriorates. Especially when manufacturing labels for mid-year and year-end seasonal products, such as labels for the food industry,
This was problematic because of the need to mass produce in a short period of time. To cope with this problem, a method of manufacturing labels in advance and keeping them in stock has been used.However, due to circumstances such as design changes, there is a high possibility that defective stock will be produced. Resources were wasted and enormous costs were incurred.

The present invention has been made in view of the above circumstances, and provides a label manufacturing method capable of solving the above-described problems, reducing waste of resources, and obtaining a label with an excellent appearance. That is the task.

Then, as shown in FIG. 4, the back surface 2b (printing surface) of the adhesive base paper 5 is transparent to the base paper 1 using a urethane-based moisture-curable hot melt adhesive 6 on the base paper 1 side. The films 2 are laminated to form a laminated film 7. Then, each layer from the transparent film 2 to the adhesive layer 3 of the laminated film 7 is punched into a desired shape and half-cut, and unnecessary portions are removed, whereby the label 8 shown in FIG. 1 is obtained.

As the transparent film 2 used in this manufacturing method, for example, polyethylene terephthalate, polyethylene, polystyrene having a thickness of 9 to 100 μm,
Examples include films made of polypropylene, vinyl chloride, and the like. The base paper 1 has a thickness of 9-11.
0 μm paper, biaxially oriented polypropylene film, polyethylene terephthalate film, vinyl chloride film,
A film made of a polyethylene film, a polystyrene film, or the like is used. Further, the pressure-sensitive adhesive layer 3 preferably has a thickness of 15 to 30 μm made of a pressure-sensitive pressure-sensitive adhesive such as an emulsion-based, rubber-based, or acrylic-based pressure-sensitive adhesive.

In the method of manufacturing such a label 8, a desired design is reverse-printed on the back surface 2b of the transparent film 2 by gravure printing, so that the printing condition of the printed surface is improved. That is, high-luminance gold-silver printing is performed on the transparent film 2 by gravure printing,
Since it is possible to print a light yellow color (without white-out) with the transparent ink, it is possible to easily obtain the label 8 which is comparable to the conventional label 18 provided with gold or silver foil.

In addition, since the transparent film 2 reversely printed in advance is bonded to the adhesive base paper 5, the waste of resources can be reduced and the cost can be reduced. That is, as a method corresponding to a case of mass production in a short period of time, the transparent film 2 on which the desired design is reverse-printed is manufactured in advance and stocked, and after the order is placed, the transparent film 2 is placed on the adhesive base paper 5. The method of laminating can be adopted, and even if defective stock occurs due to circumstances such as a change in design, the expensive adhesive base paper 5 is not wasted. Therefore, as compared with the conventional method in which finished products are manufactured in advance and stocked, resources can be wasted less and costs can be significantly reduced. further,
