Embodiment Construction

[0103] Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. First, the structure of this embodiment will be described. As shown in Figure 1, the printing processing machine 10 of the present invention is equipped with the printing section 11 that the image on the negative film N is exposed on the color printing paper P1 or P2 as the photosensitive material, and the exposure The processing section 21 for various processes such as developing, fixing, washing, drying, etc. of the color printing paper P1 or P2.

[0104] At the lowermost part of the printing section 11, a printing paper cassette 16 for storing the color printing paper P1 in a roll shape and a printing paper cassette 17 for storing the color printing paper P2 in a roll shape are provided. On the respective sides of the printing paper box 16, 17, the type of color printing paper P1 or P2 (according to the type determined by width, paper roll length, surface type,...

Abstract

A method for determining a state of a processing solution in a printer processor comprises the steps of: (a) storing change history of at least one of the exposure condition correction parameter values; and (b) determining whether or not the state of the processing solution is in a preferable state based on the stored change history of at least one of the correction parameter values. Therefore, the characteristics of the change in the processing solution state appear in the history of change of the exposure condition correction parameter values. In other words, the processing solution can be determined whether or not it is in a preferable state based on the history of change of the correction parameter values.

Description

technical field [0001] The present invention relates to a method for judging the state of a processing liquid in a printing processor and a printing processing machine, more specifically, to exposing an image onto a photosensitive material by using light irradiated from a light source, and treating the photosensitive material with a processing liquid, At the same time, it has the function of correcting the exposure conditions at least according to the change of the light source light quantity, the change of the photosensitive material characteristic and the change of the treatment liquid state by adjusting a plurality of correction parameters for the correction of the exposure conditions. The judgment of the state of the processing liquid in the printing processor Method and print processor. Background technique [0002] Generally speaking, in a printing processor used in a small-scale development hall, the image on the developed negative film is exposed to the printing pape...
