• Grayscale 16-bit: stores final images as 16-bit grayscale TIFF files.
is preserves the full tonal range captured by the scanner, but creates
files that many applications cannot read. To obtain a grayscale result,
FlexColor combines information from all three RGB color channels.
• Lineart: creates 1-bit images in which each pixel is either 100% black or
100% white. ese files are even smaller than grayscale images. Use this
mode if your originals are, for example, pen and ink drawings. To adjust
the threshold at which the input will jump to either black or white, use
the Gradations window. See “Setting the reshold for Lineart Scans”
on page 97 for more information. ICC profiles have no effect when you
use this mode.
• CMYK: creates print-ready color images. You must set up an ICC
profile to create CMYK images directly from FlexColor. See “ColorSync
or ICM Tab” on page 47 for more information about ICC profiles.
Frame
Use this pop-up menu to choose the original holder you will be using for
your scan.
Resolution PPI
Defines the resolution of the output image. Set this value according to
the requirements for your printed output. Most high-quality color work
uses 300 ppi. Newspapers typically use less (150 to 200 ppi). On-screen
display, such as for the web, requires only 72 ppi. See “Size Controls” on
page 25 for more information about PPI and image sizing.
Zoom
e level of magnification applied when the image is saved. See “Size
Controls” on page 25 for more information about zooming and image
sizing.
Descreen
If you are scanning an offset-printed original, then this setting will
compensate for rosettes in the original. It attempts to prevent moiré
patterns from appearing in your print, at the expense of defocusing the
image. e higher the setting, the more extreme the effect will be.
