-- part contents for card part 1
----- text -----
Grayscale mode generates four bits of information for each dot of the original
(the other modes record only one bit for each dot).  For every dot recorded, the scanner can store a four-bit binary number corresponding to one of 16 levels of gray (24=16). 

-- part contents for card part 4
----- text -----
The 16 actual shades of gray depend on the settings of the contrast and brightness parameters.

Using grayscale, you can take advantage of higher-resolution printers.

----- text -----
The information recorded in grayscale mode gives far greater potential for manipulation than that recorded in halftone mode.  Applications such as Image Studio from Letraset can manipulate grayscale information for superior graphic effects.

Applications such as Image Studio from Letraset can manipulate grayscale information for superior graphic effects.


-- part contents for card part 12
----- text -----
Because a grayscale scan records four bits of information for each pixel, the memory or disk space used by one scan is four times as much as for a line art or halftone scan of the same size scan area, which records only one bit per pixel.  Recall, however, that the data is automatically spooled to the hard disk.
