本発明は多種多様な透かし画像、さらに濃淡がある透か
し画像を有する抄紙の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Application of the Invention) The present invention relates to a method for producing paper having a wide variety of watermark images, and furthermore, a watermark image having shading.
（従来の技術）

クロフィルムを圧着し。(Prior art) Conventionally, as a method for producing paper having a watermark image, two methods are: gluing a paper pattern cut out in the pattern of the image onto a papermaking mesh; and (2) attaching a photosensitive resin liquid to a flat mesh plate made of synthetic resin or metal fiber. A monochrome film with an image taken on it is then pressure-bonded to a dried photosensitive resin plate.

が知られている。A method is known in which paper is made by irradiating this with light and printing it, and then dissolving and removing the resin in the unexposed areas and stacking the halftone plate on a paper making cylinder.
（発明が解決しようとする問題点）

方法が行われていた。(Problems to be Solved by the Invention) However, in all of these methods, the papermaking pulp liquid does not pass through the watermark, and if the watermark has a large area, continuous paper waste cannot be formed. Since it was not possible to produce watermarked paper with the desired image in the process, the method used was to prepare a thin paper layer corresponding to the watermarked area in advance, and then layer the non-watermarked area on top of it. .
（問題点を解決する手段）
本発明者らは前記の問題点を解決するために鋭意検討し
た結果、透かし部に相当する網部分にも濾水孔を設ける

像の濃淡に応じて連続した紙屑を形成する事を見いだし
本発明に到達した。(Means for Solving the Problems) As a result of intensive studies in order to solve the above problems, the inventors of the present invention found that by providing drainage holes also in the mesh portion corresponding to the watermark portion, the paper making liquid can be distributed throughout the paper making process. The present invention was achieved by discovering that the watermark part also forms continuous paper waste depending on the shading of the image.

たは画像の濃淡に対応したポジフィルム。That is, 9 the present invention provides that when producing paper having a watermark image from a pulp dispersion using a papermaking halftone plate, the local opening area ratio of the halftone plate with an image used corresponds to the density of the image and is at least 5%. Regarding a method for manufacturing paper having a watermark image, which is characterized by using a papermaking halftone plate having drainage holes distributed as described above, more specifically, as a papermaking halftone plate having 60
- A photosensitive rosin board is prepared by providing a photosensitive resin layer on a 150-mesh support flat mesh, and an image pattern paper or a positive film corresponding to the shading of the image is placed on the resin board.

の製造方法に関する。Further, preferably, a paper halftone plate is used in which a dotted sheet or a contact screen or the like having a light-shielding area ratio of 5 to 40% is placed, exposed and printed from two surfaces, and the photosensitive resin in the non-exposed area is eluted and removed. The present invention relates to a paper manufacturing method characterized by using a paper making liquid whose viscosity has been adjusted by adding a thickener such as polyethylene oxide.
本発明において開口面積率は次の式で算出される。In the present invention, the opening area ratio is calculated using the following formula.
開口面積率＝Ｂ／ （Ａ＋Ｂ）

Partial area ratio) is 35-50
% can be suitably used. If the mesh of the supporting plate-like mesh does not have 60 grooves, the resin layer is likely to be damaged, and
If it exceeds 50, it is not preferable because the passage resistance of the paper making liquid is large and it becomes difficult to make paper in thick paper waste portions. or.

The sheet preferably has a light-shielding area ratio of approximately 5-40%. If it is less than 5%, the paper making liquid cannot pass through that part and a stable continuous paper layer is formed.
If it exceeds 0%, the amount of paper making liquid passing through is large and the intended design cannot be expressed, which is not preferable. The dotted light-shielding figures to be arranged may be disk-shaped, elliptical, star-shaped, square, or other shapes as long as the paper-making liquid can pass through holes of that shape.

Further, in the non-image portion of this halftone plate, the resin was eluted only from the halftone dots of the halftone sheet, and the open area ratio was about 30%. Such a mesh plate was wound and fixed on a stainless steel wire (80 mesh, porosity 30%) of a circular cylinder with a diameter of 1.2 m, and placed in a cylinder paper machine vat to produce L-wood pulp with a freeness of 20'SR. A sticky agent: polyethylene oxide having a pulp solid content of 0.5% based on the pulp solid content was added to the slurry, and paper was made through a paper making liquid adjusted to 0.3% based on the solid content of the solution.

I did it. For this reason, since the mesh of the support was large, the photosensitive curing resin fell off from the support, and the obtained image could not be reproduced as in the original. Further, when a 200 mesh paper was used, the support itself did not have sufficient strength and paper could not be made continuously for a long period of time.
