ScanWizard 5 allows direct scanning in the following color spaces
described below. The desired color space in ScanWizard 5 can be
selected in the Type box in the Settings window.
RGB Color
RGB images use three colors (Red, Green, and Blue) to reproduce
up to 68.7 billion colors. Because scanners and monitors are RGB
devices, the RGB color space is the most commonly used space for
capturing and displaying images. ScanWizard 5 offers standard RGB
and 48-bit RGB color selection, with the 48-bit option available for
the Microtek professional pre-press scanners.
Grayscale
Grayscale images use shades of gray to simulate gradations of color
or tonal values, and contain 8 bits per pixel. The Grayscale 16-bit
option is provided in ScanWizard 5 for professional pre-press
scanners.
Web/Internet Colors
This mode is useful for displaying images on the Web or Internet.
Output for the Web/Internet color mode in ScanWizard 5 is 8-bit,
256 indexed color images.
Line Art
Line Art images are made up of one bit of color (black or white) per
pixel. Few editing options are available in this mode, but this mode
is useful for images consisting purely of black and white or even
single colors, such as mechanical drawings, blueprints, or fine-line
illustrations.
Black-and-White Diffusion
This is a single-bit black-and-white image dithered with error
diffusion. The black and white pixels are arranged in a way as to
"fool" the eye into seeing gray.
