Hi Sandy

I have been running the tests on your single grey profile,
I have had to reduce the ink substancially (30%) as you can see below.


PRINTER=Quad3880
GRAPH_CURVE=YES
N_OF_INKS=8
DEFAULT_INK_LIMIT=100
LIMIT_K=10.5
LIMIT_C=14
LIMIT_M=1
LIMIT_Y=17.5
LIMIT_LC=1
LIMIT_LM=1
LIMIT_LK=24.5
LIMIT_LLK=1

GRAY_HIGHLIGHT=1
GRAY_SHADOW=1
GRAY_GAMMA= 1

CURVE_K= "0;0 100;100"
COPY_CURVE_C=K
COPY_CURVE_M=K
COPY_CURVE_Y=K
COPY_CURVE_LC=K
COPY_CURVE_LM=K
COPY_CURVE_LK=K
COPY_CURVE_LLK=K


I now have 0 anf 5 and 10% which still read as 1% or pure white after scanning the steptest.
90, 95 and 100 read 93,94,95 respecively. I was going to try to reduce the inks to 40% to get better separation in the highlights, but will this reduce the blocking in the shadows as well? THought I would try reducing ink by 40%and see what happens? unless you have other suggestions??
