Digital BW, The Print

I am wondering what carbon based inks are available for printing on glossy stocks like Epson's Exhibition Glossy paper?

I have converted a R1800 to a 3K photo black printer using OEM inks.  The prints are nice except for a slight bronzing.  The bronzing is greatly reduced by waxing.

I would like to find a good B&W carbon based ink set which will work well on a glossy surface.  Since my R1800s are getting old, I would be up to purchasing a new printer.
