Digital BW, The Print

>Can you recommend a site/store that would sell the light ink, carbon? 

There are several options here.  I've mentioned MIS LLK, standard light
carbon (LC), and EZ-W as light carbon inks that I think allow the 2400 to
print better B&Ws with its Advanced B&W mode printing when they are
substituted for the yellow ink.


I just put an EZ-Warm cart into the 2400 yellow spot and found that the chip
I used for the C88 is accepted by the 2400.  The images produced look so
close to the same as the LLK or LC versions, that I think the easiest thing
might be to just buy an MIS EZ-Warm Yellow cart for testing.  See
http://www.inksupply.com/utez.cfm  As far as I know, the cart I was using in
the C88 had the standard C84 - C88 chip on it.

One would expect the EZ-W ink in the Yellow position to cause more roughness
in the highlights.  To test this, I scanned test strips that were printed
exactly the same on the 2400.  One had LLK in the Y spot.  One had EZ-W in
the Y spot.  Oddly, the EZ-W turned in better standard deviations than did
the LLK.  I'm not sure I understand why, but the measures were consistent.
In the 1600 dpi scan, the cyan and magenta dots are what show the most, by
far.  Under a loupe, I can see not differences.

He spectro curves show the image with the EZ-W in the Y spot was a bit
denser, but it was such a small amount that it's not significant.

So, the bottom line may be that the EZ-W is the best substitute carbon for
the 2400 Y spot.  The C86-88 EZ-W-Yellow carts and chips appear to work as
is in the 2400.

If you do want to go with a lighter carbon, MIS sells the standard light
carbon in several inksets, both in both carts and bulk.  The UT-R2-Warm LC
will work.  See http://www.inksupply.com/utr2.cfm#ubi   Although the carts
are the same as in the 2400, you'd also need a 2400 yellow chip.  You can
either buy these from MIS or take the one off the Epson cart.  I use a small
piece of tape across the top of the chip to hold them in place.  (Never
install a cart without a chip.  It can wreck your printer.)  As a practical
matter, the EZ-W Yellow is an easier way to go.
