Advanced
The Advanced window offers additional features
for black panel optimization.
Selecting Enable K panel destruction will
render the black panel unreadable. This is done
for security purposes so a discarded ribbon
cannot be gleaned for sensitive information.
Monochrome conversions
The monochrome panels in the ribbon can
only print binary (pure on or off) images.
Monochrome conversion is used to convert
continuous tone 8-bit-per-pixel RGB or gray
image content into binary1-bit-per-pixel content.
y Threshold – This is the simplest method
for converting from 8 bits per pixel to
1 bit per pixel. For example, the input
pixel can be a value from 0 to 255. If
the threshold is 128, any pixel over 128
becomes full on (1); and any pixel that
is less than 128 becomes full off (0).
This mode works best for text, barcodes,
line art, logos -- everything except
continuous-tone pictures. Use the slider
to set the threshold value.
y Dither error diffusion – Error diffusion
is used primarily where you have a full
color (RGB image with 8 bits per pixel) or full gray (single color but still 8 bits per pixel) that
you need to print with binary printing (can only print full-on or full-off; i.e., 1 bit per pixel).
Typically preferred over halftoning for most images. Use the brightness and contrast sliders
to adjust the levels to the desired output.
y Dither 6x6 halftoning (mixed mode only) – To simulate gray in graphics, halftones are used.
Halftones are arrays of dots arranged in a grid (6x6) to represent each image pixel as a
shade of Gray. For dark gray, more grid dots are black. For light gray, more grid dots are
white.
Preheat
This function controls the intensity of the black panel image. The higher the value, the darker the
image and vice versa. Values range from -50 to 50, default = 0
