に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for modifying the plate surface of a waterless lithographic printing plate using a silicone rubber layer as an ink repellent layer, and is particularly necessary for areas where drawing lines are missing, such as areas where images, characters, or lines are missing. The present invention relates to a method of adding new halftone dots, characters, and lines to make the ink receptive.

とが問題点の一つであつた。 Various types of waterless lithographic printing plates have already been proposed that use a silicone rubber layer as an ink repellent layer. Among these, the lithographic printing plate previously proposed by the present inventors and having a photopolymerizable adhesive layer and a silicone rubber layer on a substrate has extremely excellent performance. (Japanese Patent Application Laid-Open No. 48-94503, 48-94504 and 50-
50102) These lithographic printing plates have a number of advantages since they do not require dampening water during printing. However, one of the problems was that there was no suitable method for adding new images, characters, or lines to areas where lines were missing to make them receptive to ink.

まう。また刷版を洗浄することによつても加筆部
分の太りを生じるなどの問題点があつた。 Up until now, methods for forming drawing areas by correction include scraping away the ink-repellent silicone rubber layer with a knife, pencil, iron pen, insect pin, etc. to expose the ink-receptive surface; A method was adopted in which a solution of an ink-receptive resin was applied onto a silicone rubber layer and dried to form an image area. However, when attempting to create minute halftone dots with silicone rubber using an iron pen, pencil, etc., the dots cannot be made to a predetermined size with one or two strokes due to the repairing action of the silicone rubber itself. Furthermore, even if it appears that the additions have been made to an appropriate size on the printing plate, as printing is carried out, the added portions of the silicone rubber layer surrounding the added portions are printed larger than the predetermined size. Furthermore, washing the printing plate also caused problems such as thickening of the added parts.
また鉄筆などによりシリコーンゴム面をキズつ
けて加筆する方法では、基板の針で押されたとこ
ろは版面が凹となり、その周辺は***し凸とな
る。これが接着力の低下を起こし、さらに加筆部
の耐刷力にも悪影響を与える。 In addition, in the method of adding marks by scratching the silicone rubber surface with a pencil or the like, the printing surface becomes concave where the needle presses on the board, and the area around it becomes raised and convex. This causes a decrease in adhesive strength and also has an adverse effect on the printing durability of the added areas.
また基版の針で押されたところの凹の部分は深
すぎるとインキが入らず加筆効果が不充分とな
る。 Also, if the concave portion of the base plate pressed by the needle is too deep, ink will not enter and the added effect will be insufficient.
このような状況に鑑み、本発明者らは鋭意検討
した結果、本発明に到達したものである。 In view of this situation, the inventors of the present invention have made extensive studies and have arrived at the present invention.
すなわち、本発明は、基体上に光重合性接着層

方法である。 That is, in the present invention, when making additional corrections to the plate surface of a waterless lithographic printing plate in which a photopolymerizable adhesive layer and a silicone rubber ink-repellent layer are provided on a substrate in this order, a heated metal rod is used to touch the silicone of the corrected portion. This is a method for correcting the plate surface of a waterless lithographic printing plate, characterized in that the corrected portion is pressed against rubber and used as an ink receiving area.
本発明の版面修正方法は、すでに種々提案され
ているシリコーンゴム層をインキ反撥層とする水
なし平版印刷版のいずれにも適用することができ
る。 The plate surface correction method of the present invention can be applied to any of the various waterless lithographic printing plates that have been proposed using a silicone rubber layer as an ink repellent layer.
本発明に用いる金属棒の温度は、100℃以上好
ましくは300℃以上で、基版の変形を起こさない
範囲でなるべく高い温度が好ましい。 The temperature of the metal rod used in the present invention is 100° C. or higher, preferably 300° C. or higher, and preferably as high as possible without causing deformation of the base plate.

したものを用いることができる。 The metal rod used in the present invention needs to withstand use at 100°C or higher. Further, it is preferable that the metal rod has enough strength to be difficult to break during handling, and that the tip of the metal rod can be easily processed. For example, iron, copper,
Nickel, tin, iron alloys, copper alloys, nickel alloys, and those metals plated with chrome can be used.
本発明に用いる金属棒の先端は、加筆したい大
きさにヤスリ、ペーパー、旋盤などで加工する。 The tip of the metal rod used in the present invention is processed to the desired size using a file, paper, lathe, etc.

熱伝導の点から先端温度が上昇しにくいことがあ
る。その場合金属棒を保温するか、加熱温度を上
げるような方策を考慮する。 An example of processing a metal rod used to add fine lines or minute dots is to machine the tip of a copper alloy rod with a diameter of 5 mm using a lathe so that the tip angle is 30°, and then use #400 sandpaper. so that the tip is 50 microns. If the tip is made too acute, the temperature at the tip may be difficult to rise due to heat conduction. In that case, consider measures such as keeping the metal rod warm or increasing the heating temperature.

の精密ハンダゴテを用いると良い。 The metal rod used in the present invention can be heated by direct flame or electricity, but
When exposed to an open flame, the tip of the metal rod quickly cools down and only adds 1 or 2 spots.
You can only make small additions. Therefore, it is most preferable to use a method of heating a metal rod using an electric heating method. The tip of the metal rod is always heated to a uniform temperature, so you can find the missing parts and add them carefully. Most preferably, a commercially available precision soldering iron is used.
次に本発明を図面により説明する。 Next, the present invention will be explained with reference to the drawings.

を示すものである。 Figure 1 shows the cross-sectional structure of a waterless lithographic printing plate disclosed in JP-A-48-94503, in which 1 is a substrate, 2 is a photopolymerizable adhesive layer, and 3 is a silicone rubber layer. , 4 are ink receiving parts. By pressing a heated soldering iron 5 against the image-deficient portion of this printing plate as shown in FIG.
As shown in FIG. 3, a desired added portion 6 is obtained.
FIG. 4 shows, for example, a waterless lithographic printing plate having a silicone rubber layer as an underlying layer disclosed in Japanese Patent Application Laid-Open No. 50-66304, which has been subjected to additions and corrections in the same manner as described above.

肉不良が起こらないことである。また印刷枚数を
増やしていつた場合、網点の太り、線の太りがな
く、刷り始めから安定した網点や線を加筆でき
る。 The advantage of the present invention, compared to the conventional method, is that there is no repair of the silicone rubber, so there is no ink adhesion failure at the beginning of printing. Furthermore, when the number of prints is increased, the halftone dots and lines do not become thick, and stable halftone dots and lines can be added from the beginning of printing.
従来法では基板まで針が到達し、基板の針で押
されたところが凹となり、その周辺は***し凸と
なる。これが接着力の低下を起こして、加筆部の
耐刷力に悪影響を与えていたが、本法では基板に
キズをつけずに加筆することができる。 In the conventional method, the needle reaches the substrate, the part of the substrate pressed by the needle becomes concave, and the surrounding area becomes raised and convex. This caused a decrease in adhesive strength, which had an adverse effect on the printing durability of the added areas, but with this method, additional notes can be added without damaging the substrate.
また従来法では、基板の針で押されたところの
凹の部分は深すぎるとインキが入らず加筆効果が
不充分となつたが本法では基板にキズをつけずに
加筆することができる。 In addition, in the conventional method, if the concave portion of the substrate pressed by the needle is too deep, ink will not enter and the effect of additional writing will be insufficient, but with this method, additional writing can be done without damaging the substrate.
以下実施例によつて具体的に説明する。 This will be explained in detail below using examples.

Using the precision soldering iron used in Example 1, after turning on the power and heating it for about 2 minutes or more (temperature of about 300°C), it was lightly pressed against the silicone rubber surface of the printing plate to create halftone dots. Lines were also created by applying a ruler and drawing a line. When this printing plate was printed using Komori Printing Machine's "Sprint", clear prints were obtained from the beginning of the printing process, including the added areas.
