Digital BW, The Print

Hello all,

I tried posting this on another Group with no success.


I am missing something in understanding the curves setup and I wonder 
if someone can spot my gross error??

I have MIS quadtone inks in the epson 3000.

My stepwedge is blocky by ink cart..

Is the chart supposed to be smooth?

Here's my attemp at a curve;

PRINTER=Quad3000
CURVE_NAME=3000q4test2
GRAPH_CURVE=YES
N_OF_INKS=4
DEFAULT_INK_LIMIT=70
BOOST_K=100
LIMIT_K=
LIMIT_C=30
LIMIT_M=30
LIMIT_Y=30
N_OF_GRAY_PARTS=4
GRAY_INK_1=K
GRAY_VAL_1=100
GRAY_INK_2=C
GRAY_VAL_2=63
GRAY_INK_3=M
GRAY_VAL_3=43
GRAY_INK_4=Y
GRAY_VAL_4=13
GRAY_HIGHLIGHT=0
GRAY_SHADOW=0
GRAY_OVERLAP=0
GRAY_GAMMA=1
GRAY_CURVE=
N_OF_TONER_PARTS=0
TONER_HIGHLIGHT=0
TONER_SHADOW=0
TONER_GAMMA=1
TONER_CURVE=
N_OF_TONER_2_PARTS=0
TONER_2_HIGHLIGHT=0
TONER_2_SHADOW=0
TONER_2_GAMMA=1
TONER_2_CURVE=

Thanks in advance,
