It sounds to me like it might be the ink formulation itself that is not pure
black but has a greenish color cast to it.  If this is the case, I doubt if
you can do anything about the green cast via profiles or Photoshop except
possibly minimize the color cast somewhat.  You might try changing papers
since the paper may have a base color or brighteners in it that are causing
the green color cast; otherwise the solution might be to change ink brands
and see if a different formulation produces the same color cast.

Subject: [colorvision_group] BnW profiling on an R1800

 

I've been using a Colorvision PrintFix 2 Pro for about 9 months. I've 
calibrated both of my main displays and I'm happy with my result.
It's a Samsung 226bw. It profile's fairly neutral, with a very slight 
warm tone. 
My issue is my Epson R1800, running an Ink Republic CIS system. I've 
never got colours that I'm happy with. I'm using Ilford Smooth Pearl 
paper, because I like it's texture and the IR inks aren't very 
glossy, so glossy papers look wrong. 
So what's my problem? The output has a strong green cast. I have used 
the large patch and I've used the extended greys. I allowed the 
targets a week to dry before calibrating, I printed the targets from 
Photoshop CS2, making sure that no profile was selected. I've ran the 
Printfix pro software along side photoshop (restarting it ever time I 
made a profile change) and I can't get this paper neutral. There is a 
really strong green cast still. If I print a grey scale, it's more 
like a green scale and there's odd pink colour bands in the greys 
too. Is there something that I'm doing wrong or is that this device 
isn't accurate enough to fix this paper/ink combo?

Regards,
