CHAPTER TOC
The features of the Basic Tab are described in this section. All of the
features of this tab are available when the Image type selection is True Color,
256 Colors, or Gray 256 Scales. Refer to the table below which indicates the
SEARCH
tab features that are available for the Lineart B/W and Halftone B/W Image

True Color, RGB
In this scan mode, your scanner captures 24 bits of color image information
for every dot (pixel) in your resulting scanned image. Therefore over 16
million colors are possible.
RGB simply stands for Red-Green-Blue; these being the additive primary
colors. Additive refers to the addition, or mixing, of light of different colors.
For example, mixing equal proportions of fully saturated red, green, and blue
light produces white light.
