Color Mode (24-bit)

In the Color mode, each dot is formed by assigning it eight individual bits of data to represent each of the RGB or red, green and blue colors, which add up to 24 bits. In this mode, a dot can be expressed in approximately 16,770,000 distinct shades. This mode is useful for reproducing color prints, but generates files that are even larger than the Grayscale mode.

High Definition Color

Select for the best possible color quality. Scanning at this setting will be slightly slower than color mode.
