Digital BW, The Print

Roy, Did you use something special to reveal the data that you shared or is
that something available to the common Epson user? And is it something that
can be found easily enough? 

 

Steve’s point as well as mine, is why give up complete color control by
removing the yellow cart IF you also do color printing just to eliminate a
small amount of a possible problem? I can see doing it if B&W is the sole
intent with some tinting available, but even still how many tints are now
off the table by getting your yellow cart out of the mix?

Hi Steve,

I assume you are referring to the Y ink being replaced with LLK. If so, yes
you
get rid of the 0.87% Y but there's more to the effect. I think you'll then
find that 
neutral is shifted quite a bit and you'll need to select warmer in the tone
box 
which will then also reduce LC and LM. Is it worth it? I guess it depends.
