Photosensitive material processor

In a processor having means for processing a photosensitive material to render latent images of photographed subjects on the photosensitive material visible, means for automatically reading one or more visible test indicia, located on the same photosensitive material bearing the images of photographed subjects, to determine predetermined characteristics of the test indicia, and means for determining whether or not the characteristics of the visible test indicia are within a predetermined range, the improvement comprising:

• means for automatically creating a latent image of the test indicia on said photosensitive material;
• said processing means being adapted to process said photosensitive material to render said latent image of the test indicia visible, said visible test indicia including a plurality of images having different image densities from each other;
• and
• means for adjusting said processing means, if the characteristics of said visible test indicia are not within said predetermined range, to control one or more processing parameters of said processing means.
