Printing Preferences
Advanced Black Panel (K) Optimization
The Advanced Black Panel (K) Optimization tab optimizes black panel printing for the type
of image being printed; i.e., text, barcode, or mixed.
• Monochrome conversions: This section is used to control multi-tone printing when using
a monochrome ribbon. The available options are Dither error diffusion (default), Dither
6x6 halftoning, and Threshold (also known as Dither pure black on white); see next page
for details.
•Controls:
- Threshold sets the transition point between black (0) and white (255); i.e., pixel
values less than the threshold value would be black, and pixel values greater than the
threshold value would be white.
- Brightness controls overall the brightness of the image. Move the slider to the right to
lighten the image or to the left to darken the image.
- Contrast controls the difference between the light and dark areas of the image. Move
the slider to the right to increase the contrast and vice versa.
- Preheat controls the intensity of the image. Increase the value to enhance edges.
Reduce the value if bleeding is present. Note that the Preheat setting does not affect
the preview image but is applied to the image during the printing process.
