A printing plate main body (1) is formed which is connected to a base portion (c) that covers almost the entire surface of the printing plate (1).
上記刷版主体（１）はベースフィルムαＤが樹脂の接着
力に□よってベース部内に接合して一様に覆った２層構
造になっている。The printing plate main body (1) has a two-layer structure in which the base film αD is bonded into the base portion by the adhesive force of the resin and uniformly covered.

め、高周波ウェルターは実施出来なかった。However, with either method, if the adhesive strength of the adhesive tape is weak, there is a risk that the printing plate will peel off from the mounting film due to the centrifugal force that acts on the printing plate during high-speed printing.
Also, when the surface of the printing plate is washed to remove ink after printing and stored on the mount film, the washing water enters between the main body of the printing plate and the mount film and leaves a residue, which can be used for the next printing. There was a risk that it would leak out and stain the printed surface. Attempts have been made to attach the mount film and the main body of the printing plate by integrally bonding them together using a high-frequency welter, but the material of the mount film is polyester, and the surface of the main body of the printing plate is uniformly covered with a base of urethane resin. High frequency weltering could not be performed due to the presence of

Weld the outer periphery of the mount film to the mounting film.

問題も解決出来る。[Operations and Effects] The base film αD is completed with exposed surroundings of the base part, so if this is positioned on the mount film and the surrounding area is welded using a high frequency welter, etc., it will be easily welded and integrally joined. However, if the welding line is formed around the outer periphery of the printing plate main body, the conventional problem of cleaning water entering between the printing plate main body and the mounting film can be solved.
