Hi

I have purchased a bottle of MIS UTFS-4-Y for use in the yellow slot
of my 2100. Am I right in thinking that the existing EEM LC-in-Y curve
is the best starting point for integrating this ink in to a 4-ink warm
tone curve? What adjustments do I need to make to that curve so that
this ink takes over from the LC ink in the best place?

Thanks for any guidance
Howard
