Gamma Corrections - Xante Accel-a-Writer 812 User Manual

TIFF, PICT, EPS Formats
After scanning the image, you need to decide the format in which to
save it. The three most popular formats are TIFF (Tagged Image File
Format), PICT (from Picture), and EPS (Encapsulated PostScript)
files. If you use a scanning application such as Photoshop, make sure
to choose the appropriate line screen under Page Setup before saving
the image. This is essential for importing the image into other
applications. Some programs do not allow you to change the line
screen of an individual PICT or EPS image once it is imported.
PageMaker only allows you to change the line screen of a TIFF file.
Do this by clicking the image and choosing Image Control under the
Elements menu. Set the line screen using the formulas in the
previous section, "Halftone Scanning."
Note: Different versions of PageMaker may work differently. See
the application manual for details.
QuarkXPress only allows you to change the line screen of an
individual TIFF file. Do this through the Style menu. QuarkXPress
gives you a choice of Normal (default), 60, 30, 20 and Other line
screens. You may choose your own lpi through Other. QuarkXPress
goes a step further by allowing you to change the line screen of the
entire document in Page Setup under the File menu.
Note: Different versions of QuarkXPress may work differently.
See the application manual for details.
For more information on specific applications, see appendix B,
"Application Notes."

Gamma Corrections

XANTÉ Halftone Calibration Technology provides a sophisticated
gamma correction feature. This feature allows you to change
midrange contrasts by adjusting gray-scale values without altering
the black shadow and white highlight values at each end of the scale.
