Method
(recommended for text)
(b/w only)
• Dithered
(recommended for photos)
Converts pixels with gray
values above the middle
gray level to white, and
pixels with gray values
below the middle gray
level to black.
• Error diffusion
(also recommended for
photos)
Evaluates the gray-level
value of each pixel and
converts it to either a black
or a white value. The
amount of error is trans-
ferred to surrounding pix-
els before they are
converted. In this way, the
error is diffused through-
out the image

Instructions
Select the dithering method for
black/white images from the drop-
down dialog.
Notes:
• Not all digital copiers/scan-
ners support dithering.
• Both of the available dither-
ing methods result in a grainy,
film like texture.
Define the JPEG quality level for
the JFIF - JPEG and PDF - JPEG for-
mats as a percentage ration.
Note: An image compressed using
a higher quality will be less com-
pressed, thus taking up more disk
space than an image compressed
using a lower quality level. Using
75% JPEG quality level, you will
not normally notice any difference
from the original image.
