Real black dye ink, that's what i'am looking for to refill my Canon Pro9000 MK2. I trye more then 10 refill (bulk) inks, but all of them are dark purple, dark reddish or dark green. So i always get a color-cast when printing in the black&white modus; that is printing with only the black CLI8Bk cartridge. Have anyone a tip for an adress that delivers real black dye ink?
