Select the desired image options. These settings apply only to the embossed output.
Invert Colors – When checked, this option embosses light colors as high dots and dark
colors as low dots.
Contrast – The default setting is 0. The range is from -100 to 100. Increasing the contrast
increases the dot height difference of two colors that have intensities that are nearly the
same. By increasing the contrast, light colors get lighter and dark colors get darker.
Brightness – The default setting is 0. The range is from -100 to 100. Increasing the
brightness can be useful to increase the intensity of all the colors. This option is most often
used with images in which lines are thin and light.
Apply Chessboard Pattern – When this is checked, the printer will emboss graphics with
every second dot only, resulting in 10 dpi resolution instead of 20 dpi. With every new line,
dots are being placed underneath the spaces of the previous line, which will show like a
chessboard pattern. To separate the dots like this will help determine tactile differences in
dot heights between filled areas.
