Image Type

Select the mode you want to use for your scans on the Image Type drop-down menu.

 

Black and White— the image appears in black and white with no intermediate shades

 

of gray. That means that each pixel of the image is either 100% black or 100% white.

 

Choose Black and White if you are scanning text or pen and ink drawings. Since only

 

one bit of black or white information is required per pixel, the file size of a Black and

 

White image is only about 1/24 the size of a 24-Bit Color image.

 

Halftone— a halftone is a picture like that which is usually seen in a newspaper or

 

magazine. Since a halftone is a type of black-and-white image, the file size of a halftone

 

image is only about 1/24 the size of a 24-Bit Color image.

 

Halftone simulates grayscale by using varying dot sizes. If you view a halftone image at

 

a certain distance, it looks much like a grayscale image, but the file size is smaller.

 

When you select Halftone, a submenu appears that allows you to select a halftone

 

pattern.

 

8-Bit Gray— a single-channel image consists of at least 256 shades of gray. An 8-bit

 

scanner produces a grayscale image with 1024 shades of gray between pure black and

 

pure white. Choose this option if you are scanning black-and-white photographs.

 

With 8 bits of color information per pixel, the file size of an image is eight times larger

 

than a Black and White image and 1/3 the size of a 24-Bit Color image.

 

8-Bit Color— an 8-Bit Color image provides 256 color hues in the image. The file size of

 

a 256 color image is 1/3 the size of a 24-Bit Color image (TWAIN only).

 

24-Bit Color— a 24-Bit Color image consists of three 8-bit color channels. The red,

 

green, and blue channels are mixed together to create a combination of one billion

 

colors which give a more true-to-life quality to the image. Choose 24-Bit Color if you are

 

scanning color photos.
