Digital BW, The Print

When you print the inkpattern.psd file to establish ink limits the  
first time ink limit should be 100 and be sure to set CALIBRATION=YES  
in the profile and also calibration mode must be specified in the  
driver.

PRINTER=QUAD2200
CURVE_NAME=2200-test
CALIBRATION=YES
GRAPH_CURVE=YES

#
# number of inks must be 4, 6, or 7
# the ink limits are percentages
#   usually they are all the same but they can be individually set
#
N_OF_INKS=7
DEFAULT_INK_LIMIT=100

LIMIT_K=
LIMIT_C=0
LIMIT_M=0
LIMIT_Y=0
LIMIT_LC=
LIMIT_LM=
LIMIT_LK=
