Setting Dmin and Dmax
Adjustments can be made to the Dmin and Dmax settings in the
driver software of the workstation you are sending the data from. Any
settings sent by the drivers will overwrite the default settings on the
printer for that job.
Adjusting Dmin will set the lower limit for optical density that the
printer will produce. The Dmin default will be equal to the Ink 0
setting. It is not accessible from the front panel menu.
Adjusting Dmax will set the upper limit for optical density that the
printer will produce. It is accessible through the Default Printer
Settings menu under OD Defaults.

NOTE: OD measurements are based on the use of a reflective
densitometer with polarization filter. Approved models are Gretag
D19C (filter type 47B/P) and X-Rite 400B.
Optical Density Calibration (Setting Ink
Densities)
Optical Density should be performed (or at least checked) on a yearly
basis. Performing optical density calibration involves measuring the
density values for the primary inks and inputting them in the front
panel. Then, a test print is printed and measured to verify calibration.
To calibrate Optical Density:
1. Print Service Test Print 10.
2. Using an approved densitometer, measure all the squares in
columns A, C, E, H, K, and L, and calculate the averages for
Inks 0–3.
3. Input these values into the front panel through the Hidden
Service menu under "Set Ink Density." Return to "Ready."
