Film Tables

Film type selection via the keypad provides access to any Flash resident film tables. If a
film is selected via the keypad, it overrides any attempted film table downloads from the
host. If the host attempts to download a different film table, a "Film wrong for camera"
error is generated.

Pacing Commands

During the exposure of an image, the CRT beam must move in a smooth and consistent
manner. If the ProPalette can print faster than pixel data is being received, there will be
pauses in the exposure while the printer waits for additional data. An artifact appears on
the film as a result; appearing as a horizontal line.
A slow host computer may force the ProPalette to wait for data during a line scan. This
will result in a regular pattern of dark lines within the image. To eliminate this problem,
Pacing should be enabled on the LCD panel. This will insert a user defined wait between
scan lines, allowing the host computer to process the necessary image data. The amount
of pacing should be increased in small steps until the data wait lines have been
eliminated. An excessive pacing time will increase the total exposure time of the entire
image.
The host program or keypad can set the pacing to extend the total line time.
