Digital BW, The Print

Hi all

Looking for some advice on converting my old Epson 1200 to HEX tone 
Monochrome inks.

1/ anyone got any recomendations for ink manufacturers

2/ Are the HEX tone inks available LYson, MIS etc Dye or Pigment.

2/ I have loads of genuine Epson Black cartridges, will these work 
with the HEX colour cartride or do I have to use the black from the 
HEX maker.

Thanks for any help

Paul
