Digital BW, The Print

Does QTR support the Epson 4800?

And, is it possible to print on matte papers without using "Black"?

I need to keep PK in my printer for printing color on glossy, 
luster, ....

Went to the QTR website, but couldn't find the answer to my 2 questions.

Thanks,

Scott

Yes.  I have done curves for HPR, PJ Omega, PJ Alpha and EAM.

No you need the black.  But it only costs about £19 to swap K inks.  If you
have come from the 21/22/2400 world think about this:  a 220ml ink cartridge
costs £47, a 21/2200 cartridge about £10.  The 220ml cartridge takes about
18x the amount of ink in the 21/2200 cartridge.  (I'll let you do your own
calculations in your own currency.)  Changing the K ink is rounding error
and easily recouped from your ink cost savings - unless of course you change
it for every print.

You don't buy a Ferrari and then worry about your petrol bill...

There is a UC-NoBlack-neutral profile for the 2200.  You could do the same
thing for the 4800, but with 2 light inks rather than just one.  It mixes
light cyan and light magenta with the light gray to make the black.  You
could also try mixing full strength cyan and magenta, since the 4800 has two
light grays, that could be better; I have no idea, it would have to be
tried.
The curve description is below.  Note that the black ink is limited to 0, so
it is not used.

The 4800 is supported, but the only curves are for the MK ink. You would have to
create your own curves using PK if you are not happy with the results using MK
curves.
