Hi Sandy

Have now had a chance to rerunn all the tests with the PK...

#Sandy First trial on normal mixture (reduced by 5%)

PRINTER=Quad3880

GRAPH_CURVE=YES
N_OF_INKS=8
DEFAULT_INK_LIMIT=100
LIMIT_K=14.2
LIMIT_C=19
LIMIT_M=1
LIMIT_Y=23.75
LIMIT_LC=1
LIMIT_LM=1
LIMIT_LK=33.25
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

As close as I can get after multiple attempts. I will try increasing the contrast on the printer or reducing ink percentage by 2.5% later but for the moment ....i need to stop the tests

I am trying to linearize the data which look like this


input output
0 4 100 96
5 8 95 92
10 11 90 89
20 23 80 77
30 39 70 61
40 53 60 47
50 68 50 32
60 78 40 22
70 87 30 13
80 93 20 7
90 95 10 5
95 95 5 5
100 95 0 5


I think i need to input the subtracted data on the right in the format "0;0 5;10.....100;100" in the text file, butmy question is where?
