び自動現像機に関する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drying air control method and an automatic developing machine applied to a developing process of a photosensitive material, and more particularly to a third plate to a fourth plate used for color printing. The present invention relates to a drying air control method and an automatic developing machine that are optimal for performing a developing process of a color original film composed of:
［従来の技術］ 感光材料は、湿度が低いときには「縮み」、高いとき
には「伸る」特性を持っている。[Prior Art] Photosensitive materials have the property of "shrinking" when humidity is low and "stretching" when humidity is high.
また、これとは別に、感光材料は現像処理の前後で寸

の影響をうける結果によって生じるものである。Apart from this, the photosensitive material has a characteristic that its dimensions change before and after the development processing. This is a phenomenon in which the size of the photosensitive material at the time of exposure of the photosensitive material, the image frame size on the photosensitive material, and the image size on the photosensitive material after the development process are different. And results of being affected by humidity conditions.

処理が行なわれていない感光材料に対して感光材料が伸
びた状態になり、感光材料の寸法が処理前後で変化する
現象が生じるため、次のような問題がある。In particular, when the photosensitive material is dried in the developing process, when so-called overdrying is performed, which is excessively dried with respect to the outside air,
Since the photosensitive material is stretched with respect to the photosensitive material that has not been processed, and a phenomenon occurs in which the dimensions of the photosensitive material change before and after the processing, there are the following problems.

にずれが生じるといった問題が起こる。Since a film master for color printing is composed of three masters of cyan, magenta, and yellow or four masters including a sum of the masters, dimensional stability is required as a set of masters.
By the way, since a film for forming a master for color printing has characteristics of expanding and contracting under the influence of temperature or humidity, fluctuations in the outside air temperature and humidity at the time of exposure, and drying conditions (temperature and humidity) at the time of development processing. This causes a dimensional change before and after processing, which often causes a problem. For example, a film exposed and developed as a cyan plate is obtained, the pattern of the magenta plate is aligned with the cyan plate, and exposure is performed by contact printing, and when developed, the misalignment between the magenta plate and the original cyan plate occurs. A problem such as occurrence of a problem occurs.

制御する。[Operation] In the drying air control method and the automatic developing machine of the present invention, optimum drying conditions are set such that the dimensional change of the photosensitive material is minimized with respect to the outside air temperature and the outside air humidity in accordance with the type of the photosensitive material. The temperature of the drying air is set based on the outside air temperature and the outside air humidity so as to always provide the optimum drying condition, and the humidity of the drying air is controlled with respect to a change in the humidity of the drying air accompanying the processing of the photosensitive material.

響を受けにくく、より迅速に最適な乾燥条件を得ること

つけることができ、最適な乾燥条件を保つことができ
る。First, the temperature of the drying air is set, and the humidity of the drying air is controlled with respect to the change in the humidity of the drying air due to the processing of the photosensitive material. In the drying air control, the response of the humidity control is faster than the temperature. In addition, the humidity is hardly affected by walls, rollers and the like in the circulation system of the drying air, and the optimum drying conditions can be obtained more quickly. In addition, more uniform drying air can be blown onto the photosensitive material, and the optimum drying conditions can be maintained.

乾燥風の湿度が定常状態において、乾燥風の加湿制御を
しないで最適乾燥風湿度を得るように、乾燥風の温度を
設定することで、加湿制御をしないですむことで省エネ
ルギーになる。When the photosensitive material is processed, the dry air humidity that rises due to evaporation of the photosensitive material and the dry air humidity that decreases due to the mixing of the outside air and the dry air humidity decrease become the steady state of dry air humidity,
By setting the temperature of the drying air so as to obtain the optimum drying air humidity without controlling the humidification of the drying air when the humidity of the drying air is in a steady state, it is possible to save energy by not performing the humidification control.
即ち、連続処理を行っていくと乾燥部内は定常的な温
湿度条件になっていく。寸法安定性上の最適乾燥条件が
湿度制御を行なわない場合の定常温湿度に対して加湿が
必要な場合は、恒常的に加湿されることになり、エネル
ギーロスがあまりに大きい。このため、定常状態では加
湿制御をしないで最適乾燥風湿度がとれるような乾燥温
度条件を設定する。That is, as the continuous processing is performed, the inside of the drying section becomes a steady temperature and humidity condition. When humidification is required for the steady temperature and humidity when the optimal drying conditions for dimensional stability do not perform humidity control, the humidification is performed constantly, resulting in an excessively large energy loss. For this reason, in the steady state, the drying temperature condition is set so that the optimum drying air humidity can be obtained without performing the humidification control.
また、乾燥風の湿度が定常状態に達していないとき
に、最適乾燥風湿度を得るように実質的に乾燥風の加湿
制御をする。乾燥風の湿度が定常状態に達していないと

いて、湿度を制御する方式を採用することでレスポンス
の早さや設定精度を高めることができ、効果的に常に安
定かつ最適な乾燥条件で乾燥できる。Further, when the humidity of the drying air has not reached the steady state, the humidification of the drying air is substantially controlled so as to obtain the optimum drying air humidity. If the humidity of the drying air does not reach the steady state, if the humidification control is not performed but the temperature is controlled, the response is slow, so that it is not always possible to obtain the optimum conditions for the continuous processing of the photosensitive material. For this reason, by adopting a method of controlling the humidity while keeping the temperature constant, the response speed and the setting accuracy can be improved, and the drying can always be performed effectively and stably under optimum drying conditions.
このような、実質的に乾燥風の加湿制御は、加湿器、
また返送風率を減少させ、さらに加湿器と返送風率を減
少させる方法とが併用でき、簡単な構成で加湿制御を行
なうことができる。Such humidification control of the drying air is substantially performed by a humidifier,
Further, the return air rate can be reduced, and furthermore, a humidifier and a method for reducing the return air rate can be used together, and humidification control can be performed with a simple configuration.

ギーになる。When the film is processed, the dry air humidity, which rises due to the evaporation of the film and the dry air humidity that decreases due to the mixing of the outside air and the dry air humidity, becomes the steady state of the dry air humidity,
By setting the temperature of the drying air so as to obtain the optimum drying air humidity without controlling the humidification of the drying air when the humidity of the drying air is in a steady state, it is possible to save energy by not performing the humidification control.

条件を設定する。That is, as the continuous processing is performed, the inside of the drying section becomes a steady temperature and humidity condition. When humidification is required for the steady temperature and humidity when the optimal drying conditions for dimensional stability do not perform humidity control, the humidification is performed constantly, resulting in an excessively large energy loss. For this reason, a drying temperature condition is set so that the optimum drying air humidity can be obtained without performing the humidification control in the steady state.

簡単な構成で加湿制御を行なうことができる。As described above, when the humidity of the drying air has not reached the steady state, the humidification of the drying air is substantially controlled so as to obtain the optimum drying air humidity. If the humidity of the drying air does not reach the steady state, if the humidification control is not performed but the temperature is controlled, the response is slow, so that it is not possible to always take the optimal condition for the continuous processing of the film. Therefore, by adopting a method of controlling the humidity while keeping the temperature constant, it is possible to improve the accuracy of setting the quickness of the response, and it is possible to always dry effectively under stable and optimal drying conditions. Substantially the humidification control of the drying air can be used together with the humidifier, the method of changing the return air rate, and further reducing the humidifier and the return air rate,
Humidification control can be performed with a simple configuration.

The drying air temperature is set based on the outside air temperature and the outside air humidity so as to satisfy the conditions, and the drying air humidity is controlled with respect to the change in the drying air humidity accompanying the processing of the photosensitive material. It controls the humidity of the dry air in response to the change in the humidity of the dry air due to the processing of the photosensitive material. Optimum drying conditions can be obtained more quickly without being easily affected by walls and rollers in the circulation system. In addition, more uniform drying air can be blown onto the photosensitive material, and the optimum drying conditions can be maintained.

省エネルギーになる。Further, when the photosensitive material is processed, the drying air humidity, which rises due to the evaporation of the photosensitive material, and the drying air humidity, which decreases due to mixing with the outside air, become the steady state of the drying air humidity. In a steady state, by setting the temperature of the drying air so as to obtain the optimum drying air humidity without controlling the humidification of the drying air, it is possible to save energy by not performing the humidification control.

When humidification is required for the steady temperature and humidity when the optimal drying conditions for dimensional stability do not perform humidity control, the humidification is performed constantly, resulting in an excessively large energy loss. For this reason, in the steady state, the drying temperature condition is set so that the optimum drying air humidity can be obtained without performing the humidification control.

かつ最適な乾燥条件で乾燥できる。Further, when the humidity of the drying air has not reached the steady state, the humidification of the drying air is substantially controlled so as to obtain the optimum drying air humidity. If the humidity of the drying air does not reach the steady state, if the humidification control is not performed but the temperature is controlled, the response is slow, so that it is not possible to always take the optimal condition for the continuous processing of the photosensitive material. For this reason, by adopting a method of controlling the humidity while keeping the temperature constant, the response speed and the setting accuracy can be improved, and the drying can always be performed effectively and stably under optimum drying conditions.
