Description of the Related Art In recent years, in the industry of luxury goods such as sake and wine, a label (sometimes called a label) having a handmade folk art-like appearance has been favored since conventional paper has been completely devoted. Have been. The appearance of a Japanese paper label meets these demands, giving a handmade warmth not found in Western paper. In particular, labels that have long fluffy fluff on the cut end (outer peripheral edge) of the label and that have a crater-like pattern on the surface of the paper layer (which is called a “water-fall pattern” in the papermaking industry) have been prized. The fluffy cut is 1-5
It can be obtained by tearing paper containing paper fibers of 0 mm, but a label having a regular shape such as a rectangle or an ellipse cannot be obtained. In order to obtain a regular shape, an "ear lattice" (a lattice or lattice pattern formed by arranging tissues that have easily broken paper in a line) corresponding to the shape is formed at the time of papermaking. By cutting the Japanese paper having the ear lattice along the lattice by a tear-off operation, a well-shaped label having fluff on the periphery can be obtained. The waterfall pattern is such that when water drops are dropped on paper fibers in papermaking, the paper fibers are scattered in a crater shape, and a unique and warm appearance is obtained.

は断りの無い限り、５枚重ねで測定した秒数で示す。[0003] Japanese paper having such an ear lattice and a falling water pattern has been produced as hand-made Japanese paper. Since most of the manufacturing methods are manually performed, the production amount is limited, and thus it is not suitable for labels that require mass production. In addition, the hand-making process is a method of allowing water to pass through a net by natural fall, so that it is necessary to roughen the paper fiber, and there is a restriction that only paper having low air permeability can be obtained. In addition, the air permeability described in this specification is
Gurley test method specified in JIS P-8117 is 10
It is the number of seconds for 0 cc of air to pass through the paper piece, and in this specification, unless otherwise noted, it is shown as the number of seconds measured for five sheets.

There was a problem that could not be done. Therefore, the method of printing hand-made Japanese paper with a water-drop pattern has been manual work such as screen printing by manual feeding and offset printing by manual feeding. The current state of production of Japanese paper with ear lattices and water drops is in a state of small production at high cost, and production of machine-made paper suitable for general-purpose labels produced in large quantities at low cost was desired, but difficult. And it was. Since the method and the equipment for making the ear lattice and the falling water pattern are completely different, it is considered difficult to make the machine by the machine-making method.There is no example of this kind of washi being practically produced by the machine-making method. There were no examples of successful printing with automatic paper feed of an offset printing press.

大幅に低減され、品質も一定になる。[0010] By separately making an ear lattice and a water drop pattern and bonding them together in a wet paper state (hereinafter referred to as "making together"), the machine making method which has been conventionally difficult has been successful. The bonding in the wet paper state does not particularly require an adhesive, and is performed only by the entanglement of the paper fibers between the paper fiber layer having the ear lattice and the wet paper having the water-drop pattern. Therefore, the paper quality and texture are maintained, and continuous papermaking is performed in-line, so that the cost is greatly reduced and the quality is constant.

様と呼ばれる模様が現出される。The weight of the paper or the thickness of the paper in the wet paper can be adjusted by the fiber concentration of the pulp liquid, the papermaking speed, the amount of pulp liquid falling from a short net, and the like. The concentration of the pulp solution is not limited, but is appropriately selected based on the workability and papermaking quality, usually about 0.2%. To improve the dispersion of paper fibers and the quality of papermaking, add a toro in the case of mulberry fiber (aka kaz) to disperse the paper fiber with appropriate viscosity. The papermaking speed depends on the size of the papermaking machine, the drying capacity and the thickness of the wet paper, but is appropriately selected based on a speed of 10 to 50 m / min. The fibers are dispersed in a crater shape due to the drop pressure of the surface of the wet paper and the scattering of moisture when the water drops fall on the papermaking paper, and a pattern called a crater pattern or a water drop pattern appears on the wet paper.

もできる。When the paper passes between the mesh 3 and the press roller 19, it is suction-dewatered to form a paper fiber layer containing a small amount of water. You can get Japanese paper. Further, if necessary, the paper fiber layer obtained from the downstream circular mesh may be laminated with the circular mesh 3 and the pressing roller 19 to obtain a machine-made Japanese paper having another function. For example, increasing the air permeability by combining paper fiber layers with a short fiber length to increase the air permeability, calendering the paper after papermaking to increase the air permeability by making the paper fibers dense, etc. The result is a sheet that can be printed at high speeds such as offset printing. With conventional handmade Japanese paper, it has been extremely difficult to increase the air permeability suitable for a sheet-fed offset printing press, for example, to an air permeability of 3.8. In addition, it was difficult to maintain the air permeability at a constant level so as to be suitable for printing by the conventional hand-making method. According to the method for producing label paper of the present invention, such air permeability can be improved and the quality can be maintained at a constant level, and a Japanese paper having an ear lattice and a water-drop pattern can be provided.

しくは進行方向の前方位置である。The label paper of the present invention can be obtained as a long roll having an appropriate width and an arbitrary length. The obtained roll is cut into sheets on the basis of the ear lattice, and a sheet suitable for a sheet-fed offset printing press is obtained. Labels and labels can be obtained by printing on the obtained paper and separating the ear lattice. The printing method is letterpress printing machine, offset printing (aka planographic printing) machine,
Any sheet-fed printing machine such as an intaglio printing machine or a flexographic printing machine can be used. In the paper feeding method of such a printing machine, a paper is sucked up by a rubber suction pad or a metal suction port.
If the air permeability is low at the time of siphoning, the siphoning of the paper becomes insufficient and it becomes difficult to move the paper, and printing by automatic paper feeding with conventional hand-made Japanese paper was impossible.
In the present invention, since the air permeability is adjusted so as to be suitable for the suction of the paper feeding machine in the machine-making, automatic paper feeding becomes possible. In printing paper feeding, a wind called “air blow” is blown onto the upper portion of the stacked papers at the same time as the suction, so that the upper paper is lifted up, and the effect of preventing “two sheets stacked” is exhibited.
The positions of the suction pad for feeding paper and the air blow are not particularly limited, but are a front position or a rear position in the traveling direction of the stacked sheets, and are preferably front positions in the traveling direction because the sheets are easily broken by the ear lattice. It is.

利である。The printing speed depends on the type and capacity of the printing press and the properties of the paper, but printing at a speed of 3,000 to 20,000 sheets per hour is possible. Multicolor printing of 7 colors is also possible. Such a speed is remarkably higher than the conventional manual paper feed rate of 100 to 2,000 sheets per hour. In addition, compared to the conventional method of manually performing single-color printing by manual paper feeding to produce multiple colors, the method of the present invention exhibits remarkably high productivity.
In particular, the label paper of the present invention has high productivity, can be printed at high speed, and is advantageous in terms of cost as a label printed in large quantities for favorite items such as sake, wine, confectionery and other foods.
