Using
the Scanner Functions
Monochrome mode (standard)
Use
this mode when you want to scan a black and white image. If
you scan a color image in monochrome, you may need to specify a
dropout color to recover or delete detail. See Dropout color below.
Standard monochrome scanning uses all three lamps so that the
original image is scanned with white light, thus minimizing the
dropout color.
Dropout color (monochrome scanning only)
Use this mode when you scan a color image in monochrome and
you need to recover detail, eliminate background color, or eliminate
unwanted detail. Dropout color is the color that is not recognized by
the scanner. You can choose either green, red, or blue, depending on
the colors on the original images.
Halftoning Mode
Halftoning is a digital process which simulates continuous gray
tones or continuous colors. Some printers, however, cannot print
these continuous tones. Halftoning is suitable for original images,
such as photographs, that have continuous tones. Use halftoning if
your output device can reproduce only 1 to 2 bits/pixel/color image
data.
Note:
Avoid changing the size of a halftoning processed image
with your application software. Use the scanner’s zoom function
instead to select the desired image size.
You can enable or disable the halftoning process itself, and select
from the three halftoning modes, A, B, or C.
