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 or K Panel.
Options are Dither error diffusion, Dither 6x6 halftoning, and Threshold (also known as
Dither pure black on white); see next page for details.
The conversion option selected determines which of the controls is enabled; i.e., selecting
Threshold enables the Threshold, Preheat, and Intensity 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. Default is 128.
- 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.
