24bit Color Mode
In the 24bit Color mode, each dot is formed by assigning it eight bits 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
12bit Grayscale mode. Use this mode when the image is to be printed on a color
printer.
36bit Color Mode (FS2710 only)
In this mode, each dot is formed by assigning it 12 bits to represent each of the
RGB colors, which add up to 36 bits. This mode creates a color smoother than the
color created with the 24bit color mode. The size of an image saved in this mode is
approximately twice the size of a 24bit color image. However, the displayed image
is the same as the 24bit color mode because the difference in image quality cannot
be accurately reproduced on the screen. Use this mode when you need a color
image with finely attenuated color tones.
Caution
• If you are using a software application which cannot handle 12bit grayscale or
36bit color images and you attempt to scan a 12bit grayscale or 36bit color
image, your system may hang up. Before you attempt to scan images in these
formats, refer to your software application user’s manual to confirm whether
or not your application can handle such images. Photoshop version 4.0 or
later, and Photoshop LE provided with the package, can handle 12bit
grayscale and 36bit color images.
Hint
• If you scan an image in 36bit color with Photoshop, which is compatible with
36bit color, the image is scanned as a 16bit Channel Mode image.
• If you are using the 2700F, you cannot select the 12bit Grayscale mode or the
36bit Color mode.
• If you are using monochrome film, you cannot select the 24bit Color mode or
36bit Color mode.
