Copying apparatus, print evaluating method for copying apparatus, method for setting printing conditions, and copying apparatus controller

摘要

A copying apparatus provided with a light-attenuating filter used for controlling copying conditions. The light-attenuating filter is formed of a nontransparent member in which a multiplicity of small holes or small-width slits are provided. In setting the printing conditions for the copying apparatus, a film development-evaluating film with an evaluating latent image recorded thereon is developed, the image on the evaluating film developed is photometrically measured and printed on a paper, the printed paper is developed, and the density of a print obtained by development is measured so as to set the printing conditions. To photometrically measure the print, a punched hole provided in the paper is detected to photometrically measure a central portion of the image plane.
