Image Dmin, Image Dmax, and Border Dmax

The Printer can set the Image Dmin and Image Dmax for all of the images on a page. The
Image Dmax must be less than or equal to the Border Dmax. The lowest printable Image
Dmin is the calibration test page Dmin. The Dmin can be set to zero. When a page has
a clear border, the trim is dark. When there is a black border, the trim is white.
You should understand the relationship between image density restriction and contrast
adjustment. If you reduce both Image Dmax (restrict) and contrast (negative contrast),
the density will be reduced more than you might expect.
The 2180 Laser Printer allows each imaging device to select Image Dmin, Image Dmax,
and Border Dmax individually. For example, an ultrasound user might select an Image
Dmin of 0.0, an Image Dmax of 2.5, and a Border Dmax of 2.8, while a CT user might
choose an Image Dmin of 0.0, an Image Dmax of 3.0, and a Border Dmax of 3.0. Border
Dmax allows you to select the highest printable density.
