[Sensitivity differences of different emulsion numbers for different UV/blue-sensitive films].

The German standard series DIN 6868 does not include a separate requirement for deviations in the sensitivity of different emulsion numbers or, respectively, the relative contribution of the film to sensitivity S of a screen film system (SFS) whose sensitivity is determined according to DIN 6867-1 [1]. The inclusion and interpretation of these contributions in the test body exposure according to DIN 6868-3 [2] has not proved to be of value since an unambiguous error recognition is only possible with considerable experimental experience (additional exposure of a sensitometer strip and interpretation of the resulting consequences). The investigations reported here demonstrate that the correlation of sensitometric parameters obtained from sensitometer strips generated with sensiometer exposure and X-ray exposure is so large that differences in sensitivity of different emulsion numbers of a screenfilm larger than delta log H > or = 0.
