A printing plate main body 1 is formed which is connected to a base portion 23 that covers almost the entire surface of the base film 11.
上記刷版主体１はベースフイルム１１が樹脂

After positioning the printing plate main body on the mount film, conventional methods for attaching the printing plate main body include adhering adhesive tape 13 around the printing plate main body while holding it down, and fixing the base part of the printing plate main body and the mount film.
Alternatively, double-sided adhesive tape was applied in advance to the back surface of the printing plate main body, and this was placed on the mounting film and pressed and adhered.

は実施出来なかつた。 However, with either method, if the adhesive strength of the adhesive tape is weak, there is a risk that the printing plate itself will peel off from the mounting film due to the centrifugal force that acts on the printing plate body during high-speed printing. When the surface of a printing plate is washed to remove ink and then stored while attached to a mounting film, the washing water enters between the main body of the printing plate and the mounting film and remains, which may flow out during the next printing. There was a risk of staining 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 welder, but the material of the mount film is polyester, and the surface of the main body of the printing plate is made of a uniform urethane resin base. Because it was covered, high frequency welding could not be performed.

The base film 11 is completed with exposed around the base part 23, so if this is positioned on the mount film and the surrounding area is welded using a high frequency welder or the like, it will be easily welded and integrally joined. By forming the line 80 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 mount film can be solved.

の刷版の場合、ベース部２３の厚みh1は約2.0mm、
マウント部２２の厚みh2は約2.5mm、レリーフ部
２１の厚みh3は約２mmに形成するのが好ましい。 The base portion 23 is strongly adhered to the polyester base film 11 by the adhesive force of the resin itself or by the adhesive force of an adhesive applied to the base film if necessary, so that a relief is formed as shown in FIG. The portion 21, the mount portion 22, and the base portion 23 are integrally formed of photocurable resin. In the case of a printing plate for corrugated paper, the thickness h 1 of the base portion 23 is approximately 2.0 mm.
It is preferable that the thickness h 2 of the mount portion 22 is approximately 2.5 mm, and the thickness h 3 of the relief portion 21 is approximately 2 mm.

り付ける。 To fix the main body of the printing plate onto the mount film, after positioning it on the mount film using the alignment marks on the main body of the printing plate, the exposed portion of the base film of the main body of the printing plate is fixed using a known portable high-frequency welding machine or the like. Weld it to the mount film and install it as an integral part.
製作工程 次に上記刷版主体１の製作工程を説明する。Manufacturing process Next, the manufacturing process of the printing plate main body 1 will be explained.
第１図は刷版主体１の製作に用いるネガフイル
ム３とマスキングフイルム４を示している。 FIG. 1 shows a negative film 3 and a masking film 4 used for producing a printing plate body 1. As shown in FIG.
マスキングフイルム４は透明フイルム４２の一

４６ａを切り抜いて形成したことである。 The negative film 3 has a completely light-shielding surface, as shown by diagonal lines, except for the translucent pattern 31 corresponding to the mark 9. It should be noted here that the negative film 3 does not have a transparent part corresponding to the alignment mark 12 of the printing plate main body 1, and only the completely light-shielding surface of the masking film has a transparent area corresponding to the alignment mark at the appropriate position. The light portion 46a is formed by cutting out the light portion 46a.

成されている。 The semi-shading film 43 is formed by cutting out a translucent pattern 44 having a slightly larger outline than the pattern 31 corresponding to the translucent pattern 31 of the negative film 3, and the completely light-shielding film 45 is formed by cutting out a translucent pattern 44 corresponding to the translucent pattern 31 of the negative film 3. It is formed by cutting out a translucent pattern 46 having an even larger outline than the translucent pattern 44 of 43.

It is formed by making a score line corresponding to 6 and peeling off the inside of the score line from the transparent film 42.
半遮光フイルム４５は露光の約10〜15％を透過
せしめる。 The semi-shading film 45 allows about 10 to 15% of the exposed light to pass through.
尚、マスキングフイルム４は上記のものに限定

周部に略長方形の枠体７を置き、枠体７内に光
硬化性液体樹脂を流し込み、透明フイルム６上
に光硬化性液体樹脂層２を形成する。First step: As shown in FIG. 3, a negative film 3 is placed on a transparent base plate 5, and a transparent film 6 is placed over the negative film 3. Further, a substantially rectangular frame 7 is placed around the outer periphery of the transparent film 6, and a photocurable liquid resin is poured into the frame 7 to form a photocurable liquid resin layer 2 on the transparent film 6.
第２工程 光硬化性液体樹脂層２の上面に透明ベ
ースフイルム１１を載せ、該フイルム１１の上
にマスキングフイルム４を被せる。Second Step: A transparent base film 11 is placed on the upper surface of the photocurable liquid resin layer 2, and a masking film 4 is placed on top of the film 11.
透明ベースフイルム１１の下面には必要に応
じて予め光硬化性樹脂との接着性の良好な透明
接着剤（図示せず）を塗布しておく。 If necessary, a transparent adhesive (not shown) having good adhesion to the photocurable resin is applied to the lower surface of the transparent base film 11 in advance.
第３工程 第４図に示す如く透明台板５及びマス
キングフイルム４の外から光源５１からの光を
当て、光硬化性樹脂を380〜400秒露光する。Third step As shown in FIG. 4, light from a light source 51 is applied from outside the transparent base plate 5 and masking film 4, and the photocurable resin is exposed for 380 to 400 seconds.
露光によつて樹脂層の下部はネガフイルム３
のパターン３１に対応する部分が硬化してレリ
ーフ部２１となる。 Due to exposure, the lower part of the resin layer becomes a negative film 3.
The portion corresponding to the pattern 31 is hardened to become the relief portion 21.

２３となる。 On the other hand, the cured state of the liquid resin layer 2 on the side of the masking film 4 is as follows:
In the part corresponding to 6, the resin layer is thick and hardened to become the mount part 22 that is integrally connected to the relief part 21, and in the transparent part on the completely light-shielding surface 45a weakened by covering the semi-light-shielding film 43. , the upper part of the resin layer is thinly hardened in correspondence with the pattern 46 to form the base part 23 connected to the mount part 22.

光を別々に停止する。 The base portion 23 is firmly joined to the base film 11 by the adhesive properties of the resin itself or by an adhesive applied to the base film 11 in advance. The order of exposure is to first start exposing the masking film 4 side and wait for about 2/3 of the required exposure time.
Exposure from the negative film 3 side is started when the time has elapsed, and the exposure is stopped separately when the required time for each exposure has elapsed.
上記の様にマスキングフイルム４側の露光を

ト部２２に安定して一体化形成される。 As described above, by exposing the masking film 4 side before the exposure from the negative film 3 side, the mount part 22 and base part 23, which serve as the base of the relief part 21, are formed before the relief part 21, The relief part 21 is stably formed integrally with the mount part 22.
マスキングフイルム４側からの露光が終了し
てからネガフイルム３側からの露光を開始して
も可いが、この場合、時間的にロスが生じる。 Although exposure from the negative film 3 side may be started after the exposure from the masking film 4 side is completed, in this case, a time loss occurs.
尚、露光時間は形成すべき刷版の厚み、光の
強さによつて最適に決めれば可いのは勿論であ
る。 It goes without saying that the exposure time can be optimally determined depending on the thickness of the printing plate to be formed and the intensity of light.
