Choose an output type

The output type selected in the Output Type menu determines the bit depth and color palette applied to the final scan of pictures and drawings, but not for images that will be converted to text. The table on page 64 lists bit depths and color palettes for each output type that is appropriate for images of pictures and drawings.

However, the output type selected by the scanning software may not be the most appropriate for the way you will use the image. For example, when you want to print the image of a color photograph on a black and white printer, you may want to set the output type to Grayscale.

Some output types are more suitable for images that will be displayed on a monitor, others are more suitable for printing.

The table on page 64 lists results you can get with each output type for various types of originals.
