4.6Auto Masking

4.6.1 Overview

If a print is made from an image that is projected smaller than the Markers on the screen, the non-image areas of the film result in black bands running around the image on the print.

The Auto Masking Function Automatically detects the non-image areas of the film.

4.6.2 Masking Area Detection

The CCD Board (PWB-A) is detects the density of the film image.

If Auto Masking is selected on the control panel, the CCD Board (PWB-A) detects the masking area (By measuring the intensity of light) while the Scan Mirror makes a prescan motion.
