Digital BW, The Print

i do not like any of the print colors that i get with mis ut2 or the neutral utfsn.
i love the color of ebony, but do not get satisfactory results(on 1280 epson) printing black 
only. the quality just is not as good as with the 'color' converted cartridge. what can i do that 
is not too complicated? i just want to use an eboni colored cartridge, are there  eboni colored 
cartridges for the 1280?thank you.
