Scanning With the MultiPASS C5500
6-19
Scanning
Output Device: The name of the printer, printer setting, or other output
device where the scan is destined.
Res: The resolution (or dpi) equivalent to the selected print mode. For
your monitor or fax/modem, see your owner’s manual for this
specification if unknown.
ScanTastic will generate a different resolution based on your selection of
Image Type. When choosing Line Art, the number in the Res field will
be used. When Color or Grayscale are chosen, ScanTastic will choose a
resolution most appropriate to the halftone capability of your output
device.
Because halftone cells inherently limit the perceived resolution of a
scanned image, there is no reason to scan an image at a resolution
higher than 1.5 times the line screen frequency of your final output.
Keep in mind that the higher resolution scan you acquire, the more
memory, disk space, and processing time will be required to work with
the scan.
ScanTastic calculates its halftone resolution by extrapolating a figure
based on the Res field. The basic halftone capabilities of the device are
then multiplied by 1.5 to set the resolution.
N
The Monitor icon in the left most position of the panel behaves
somewhat differently than the others in the group. This icon has no
halftone calculation. This means it will always use the value supplied in
the Res field for reference.
