Digital BW, The Print

Hi all,

My first post.
I am based in the UK, and am making very good prints using Paul Roarks'home made inkset on an Epson D92. Slow and noisy though it is the cost in UK was only 30GBP.
However I am now using this inkset on a coated film that I have found, to make large negatives for alt printing, the trouble is that it easily rubs off during the rigours of contact printing. Does anybody know if a dye ink could be used with the standard base to make the 13.5% dilution needed for the three colour carts.

Thanks in advance.
