Abstract

(57)【要約】 【目的】 処理液状態の管理を簡便に高精度で行う。 【構成】 使用されるペーパーと特性が同じペーパーが 一定露光条件で露光され一定条件の処理液で処理された 場合の基準濃度D sn をバーコードでマガジンに記憶して おき、NDフィルタを透過した光により露光され貯留さ れた処理液で処理されたペーパーの露光部位及び未露光 部位に対応する基準濃度D sn を読み取る(ステップ16 3)。次に露光部位及び未露光部位の濃度D n が基準濃 度D sn に等しいか否か、濃度D n と基準濃度D sn との差 が許容範囲内か否かを判定する(ステップ164、16 6)。よって、ペーパー特性変動の影響を減少した上で 処理液状態を管理することができ、濃度D n と基準濃度 D sn との差が許容範囲外の場合、警告し(ステップ17 0)、即座に処理液の交換を促すことができる。
PURPOSE: To easily control the state of processing solution with high accuracy by providing a storage means storing information concerning the processing characteristic of paper. CONSTITUTION: A densitometer 22 and a storage device 88 are connected to a control part 60. The density of the paper at the time when the paper is exposed on a fixed exposing condition and processed with the processing solution under a fixed condition is stored in the storage device 88 as reference density D s . The densitometer 22 measures the density D of the paper after the paper is exposed on the exposing condition equivalent to the fixed exposing condition and processed with the processing solution under a use condition. The control part 60 stores a difference between the density D and the reference density D s in the storage device 88 in the case the density D and the reference density D s are not equal. In the case the difference between the density D and the reference density D s is not a value within tolerance, a warning message is displayed on a display 58 because it is judged that the processing solution must be exchanged.
