Printing Trace Screens
Although the Outdoor Viewing or Indoor Viewing color schemes
are well suited for viewing a trace screen on a color display, if you
want to print a trace screen on a black and white printer (for
example, a laser printer), you should select either the
Monochrome
grays or Black on White for printer color scheme ( Tools > Op-
tions > Preferences ) for a better printout. When the Monochrome
grays or Black on White for printer color scheme is used, a trace
screen will appear with colors that are optimized for printing on
black and white printers.
After you have set the color scheme for Monochrome grays or
Black on White for printer , the trace screen will appear with
altered colors. In the Monochrome grays color scheme, the highest
signal level is the lightest color. But in the
Dark on white
color
scheme, the lightest color is not the highest signal level.
