Digital BW, The Print

Hi,

For days now, I've been searching the Internet trying to find a 
solution for the magenta cast problem with B&W prints done on my Epson 
2100 (2200) printer. In daylight they look fine, in artificial light 
they get this horrid magenta cast. From what I've read, this cast is 
caused by metamerism of the yellow ink. Solutions seem to be dedicating 
my printer to black ink only, get a RIP or just printing black only.

Stumbling upon this group, I read several articles and tried some of 
the tips given. I really hoped that the results would be satisfactory 
so I could put more energy in taking great photo' s instead of wasting 
lots of paper and ink getting the prints right. I tried three types of 
paper (Ilford Smooth Gloss Paper, Epson Heavyweight Matte Paper and 
Hahnemuhle Fine Art Photo Rag) using photo black ink. To my surprise, 
the print made on Ilford paper had a sort of green cast and Hahnemuhle 
paper showed a definite magenta cast. How can this be???

What am I doing wrong? Should I use the Matte ink on the non gloss 
paper?

Another small question on ink cartridges: are epson 2200 and epson 2100 
cartridges interchangeable? Or does the difference in voltage between 
the USA and Europe have an influence on the working of the chip that 
sits on the cartridge?

Hope someone can help me.
Regards,
YaWie
