Hi,
I'm pretty new to C.M.  and I'm trying to be confident with  Spyder 3 
and its profiles.....
 
My setup: Monitor Eizo S1931 (I'm not a professional, therefore I assume 
this is  quite a good monitor for a lover) duly calibrated with EyeOne,
printer Epson 1400 and, of course, Printfix pro spectro with 
Spyder3print sw vers. 3.5b9; profiles comes from 225 patches target.
Photoshop CS4settings:  let's Cs4 manages colours, (printer profile made 
by Spyderprint) saturation intent, no BCP.
Printer drivers selected: paper type Epson Glossy plus (same as printer 
profiling, of course), no ICM, high speed unchecked, print borderless.
Spectro was duly calibrated on the white tile before the process. I have 
calibrate the device then measured the white tile from the Tools >
Measure menu item: the white tile is L* 90,48 and a* -1,00 b* -1,23.

The print: no colour cast, good colours, saturation ok,everything is 
good but...... there is less brightness if I compare it with the image I 
see at the monitor (also considering the different type of light).
Also if I softproof  the image (again: printer profile, no bpc, 
saturation intent) I see that the image fall down in brightness....
Better prints I see if I check BPC: more brightness (therefore better 
prints, but BPC should be left UNchecked, isn't it?) but again a little 
far from what I expect.

Why? what happens and where I'm wrong?
