Digital BW, The Print

Ernst,

I would love to see MIS or ConeTech come out with an ink set similar to the
Lysonic E but done with pigment inks. The problem in mixing them up yourself
is keeping the proper overall density. Even in blending similar inks like
MIS-FS Standard and Neutral some density shifts were obvious. I assume that
the companies have a great deal of expertise in this but I would not want to
try it myself even with a spectrophotometer.

You would have to do many trials mixing up an ink, loading it into a K
cartridge, printing a mono-ink wedge, take readings, compare them to the
visual density you want for the particular ink position you are mixing up,
adjust your formula and do it all over again until you got it right. I can
be done but a lot of work from scratch.
