Re: Help with Single Gray QTR Profile

2017-02-23 by greg@...

Thanks Sandy. I tried it last night and created a profile based off the readings. I didn't get any tone until about step 15-20 and the first difference in the dark tones came in around 80 which I believe is normal for a profile with no curve or linearization. I had to change the first reading from 27 to 26, otherwise I could not linearize it. This is the profile I made:

#PRINTER=Quad7880
#CURVE_NAME=
GRAPH_CURVE=YES
N_OF_INKS=8
DEFAULT_INK_LIMIT=100
LIMIT_K=25
LIMIT_C=1
LIMIT_M=1
LIMIT_Y=25
LIMIT_LC=1
LIMIT_LM=1
LIMIT_LK=40
LIMIT_LLK=1

GRAY_HIGHLIGHT=4
GRAY_SHADOW=4
GRAY_GAMMA= 0.07

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

LINEARIZE="26.51 27.75 28.35 29.36 31.19 34.46 39.77 46.52 53.67 60.64 66.73 73.13 77.22 80.34 82.43 84.17 85.07 85.61 86.27 86.79 87.16"


I will print it tonight and see how it works.

Thanks again,

Greg
