Digital BW, The Print

Hi

I printed an image with QTRip, Paul's curve for RedRiver Polar Matte and added a step wedge from Barry Haines Photography. (17 steps) Maybe I should have used a 21 steps.

I read the patches with my new SpyderPrintPro 4 (I,m quite a novice at printing EB6) and I got results that suppose to help me.

Up to now, I got: 
0	0,04
1	0,06
2	0,10
3	0,16
4	0,29
5	0,35
6	0,39
7	0,49
8	0,59
9	0,74
10	0,87
11	0,91
12	0,98
13	1,29
14	1,51
15	1,58
16	1,60

What bothers me is the steep step between patches 12 and 13. Actually I don't know how to correct this, how to alter the curve or how I can get a smoother readings, The print seems nice but I'm sure that I can get better results.

Thanks
