ECHO About Bayerscale:
ECHO When bayer dithering is selected, the Bayer Scale option defines the scale of the pattern (how much the
ECHO crosshatch pattern is visible). A low value means more visible pattern for less banding, and higher value
ECHO means less visible pattern at the cost of more banding. The option must be an integer value in the range
ECHO [0,5]. The Default is 2. Bayer Scale is optional.
