本発明は、現像液を循環させた現像槽内に感光
材料をＵターン搬送させて現像する印刷製版用感
光材料の現像処理方法と装置に係り、特に現像槽
内における現像液流に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for developing a photosensitive material for printing plate making, in which the photosensitive material is conveyed in a U-turn in a developing tank in which a developer is circulated, and in particular, to It concerns the developer flow.
現像液を満たした槽内に感光材料を搬送させて
現像するとき、感光材料の近くの現像液に疲労が
生じていると均一な濃度の仕上がりができず、現
像むらが生じる。現像むらの発生を防ぐためには
現像液に流れをつくればよい。 When a photosensitive material is conveyed into a tank filled with a developer and developed, if the developer near the photosensitive material is fatigued, a finish with a uniform density cannot be achieved, resulting in uneven development. In order to prevent uneven development, it is sufficient to create a flow in the developer.

真感光材料の現像では、現像液が動いていさえす
ればよく、補充液を添加する場合でも補充液が処
理槽内で均一に混入されていきさえすれば現像む
らは生じない。 When developing photosensitive materials such as general photographic film and X-ray film, all that is required is for the developer to move, and even if a replenisher is added, it is sufficient that the replenisher is evenly mixed in the processing tank. Otherwise, uneven development will not occur.

は、その現像方式が伝染現像であるために、現像
液の循環によつて生じる液流の感光材料面上での
流速の不均一および液中に生じる渦の影響で均一
な濃度の仕上りを得ることが難しい。 However, in the processing of photosensitive materials for printing plate making, such as lithographic film, in which image density is expressed as a halftone dot area, the development method is contagious development, so the liquid flow generated by the circulation of the developer is applied to the surface of the photosensitive material. It is difficult to obtain a finish with a uniform concentration due to the uneven flow rate and the effects of vortices that occur in the liquid.

乱流が生じないよう流速の均一性を保持し得るよ
う種々の工夫がなされている。 Conventionally, in order to prevent uneven development, it is necessary to prevent the developer from accumulating fatigue near the film surface, to create a liquid flow that prevents the tired developer from accumulating near the film surface, and to Various measures have been taken to maintain the uniformity of the flow velocity so that turbulence does not occur in the flow.

し得るような種々の工夫がなされている。 In addition, in the processing of photosensitive materials for printing plate making,
In particular, halogen ions are liberated from silver halide crystals being developed into the developing solution, and these tend to appear as drag lines. Since these drag lines appear as a trail in the image area and cause uneven development, various measures have been taken to quickly remove the halogen ions.

用いてもドラツグラインを著しく軽減させるよう
に設計するには容易なことではなかつた。 Conventionally, a typical method has been devised to create a liquid flow in the developer near the film surface, maintain the uniformity of the flow velocity, and prevent drag lines. As stated in the technology, inside the rack that transports the film in a U-turn with the photoresist surface inside,
A suction box that sucks the developer is installed between the rectifying plate that also serves as a guide and the side plate, and the suction box has many liquid suction ports that suck the developer between the rectifying plate and the film being transported. Similarly, on the inside of the rack, a liquid discharge pipe for discharging the developer is installed between the side plates, and the liquid discharge pipe has many liquid discharge ports that provide a uniform flow of liquid to the surface of the film being transported. Like the invention disclosed in Japanese Patent Application Laid-Open No. 55-52059,
A known method is to transport the film in a U-turn with the photoresist surface of the film facing outward, thereby creating a developer flow in the developing tank along the photoresist surface of the film and substantially perpendicular to the direction of transport. However, no matter which method is used, it is not easy to design a device that significantly reduces the drag line.

供することである。 The object of the present invention is to provide a liquid flow system that can significantly reduce the drag line without using the conventional complicated method of providing a liquid suction port or liquid discharge port in the rack or a method that requires a design that requires difficulty in adjusting the liquid flow. The object of the present invention is to provide a processing method and apparatus that can obtain the desired properties on the surface of a photosensitive material.
