Digital BW, The Print

Steve,

Yes, they are just UC LK clones -- quite warm.

> I read that UT7 contains a custom light black

Yes, it should be different, neutral LK.  I call it LK-N.

>and (1) thought this was actually just the same LK as the above

It is not supposed to be.  With the Epson driver and printing with the
sliders, the standard LK causes warmer shadows than I like.

>and (2) that LK was of little use in a 21/2200 

It is significant only when the sliders are used with the Epson driver.
Recall that the 2200/2100 with the UT7 inksets is also an "EZ" inkset that
can be printed without Photoshop or a RIP.  That entry-level and fall-back
position is important to a significant part of the user base.  You power
users are a minority.  Most want to hit "print" and get an excellent B&W
print.

>and hence could be dumped in favour of "glop".

I'm hoping the Y position works for the glop, because that makes it
consistent with the default, "EZ" approach and Epson driver.  On the 1280,
it works very well and preserves the UT2 "EZ" printing.  RIP users have more
options, but the larger market is important for the long term success of the
medium, in my view.
