True Color, CMYK: Converts RGB (video) color data into
CMYK (printed) color data using a special color transformation
process. When scanning is completed the CMYK image is ready for
printing on a CMYK color printer.
NOTE: Most ink jet printers use RGB rather than CMYK printing.
256 Colors: Scans color images using 256 colors. The 256 color
images take up less memory and hard disk space than the True
Color RGB option.
Web Photo: Scans an image at the appropriate resolution for
display on the monitor.
B/W Photo: Scans black-and-white photos using 256 shades of
gray (ranging from white to black) so you get smooth shade
transitions in your scanned image.
B/W Document: Scans text documents, black-and-white line art,
and other black-and-white documents. This selection creates the
smallest files.
FAX: Scans at the appropriate resolution for faxing.
OCR: Scans at the appropriate settings for optimal OCR
recognition.
True Color 36-bit RGB: Scans a full-color photo or document
using 36-bits of information to define each pixel. The RGB
indicates the colors of Red, Green and Blue. This setting creates
larger files than the True Color RGB setting.
B/W Photo, 12-bit: Scans a black-and-white photo using 12-bits
of data to define each pixel. This setting produces more gray shade
accuracy than the B/W Photo option, but also produces larger file
sizes.
NOTE: Not all graphic applications support 36-bit graphic files.
To determine whether the software you want to use is capable of
working with 36-bit graphics, refer to your software documentation.
