Thanks for response Paul,I have checked the cartridge loading & it's 
O.K. although the purge test pattern looks nothing like yours.Density 
of pattern looks alright but the colours dont match yours.Your yellow 
position looks yellow,mine is grey.You mentioned checking that the 
image does not have an imbedded profile but your website says "Source 
Space- Document:Gray Gamma 2.2." The image must have some sort of 
profile even if it is untagged gray--I tried this & it didn't help.
  I have just tried another variation-- +10 contrast,this has helped 
the overall appearance but there is still compression on the midtones.
  Maybe I'm expecting too much from the pigment inks but their range 
does not seem to match the dye inks.Having invested in a printer & 
dedicated greyscale inks to escape the dreaded colour casts of the 
standard colour ink sets I'm beginning to wonder about the wisdom of 
my choice.I think the next step is to try to create a curve which 
seperates the midtones more, but I am treading in unknown territory 
here so it will be trial & error.
Thanks again.Regards Pete.
