Digital BW, The Print

If I weel understand the 2 inkset have the same inks except for the EB6Y, the very light LLLK (2% ebony) that for 1400 is repleced with a neutral photo black (HP Z3100).

If this is correct I haven't understand why the photo black is not in the yellow position (so I can change from 6 to 1400 only changing one carts) but in the C position.

Can I cjange the positions (making new qtr curves) or I will find some problems with PK in Y position?

I have started to print with eboni-6  and QTR and the results are very interesting, so I'm thinking to try to have some more neutral print with eboni 1400 workflow.

Yes, Eboni-1400 omitted the 2% Eboni and put in HP PK, but not in the Y position.  See http://www.paulroark.com/BW-Info/Eb1400.pdf

The other inks were moved so that the Epson driver would work.  The chips on the carts can be easily swapped.  (Actually, I'm not sure the current MIS chips are even sensitive to position.  You might just insert the carts in the new positions and see if the printer works.  Let us know.)

You can change the positions in QTR and it works find.  That is, the jets all behave the same.  So, use the curve for the position that the ink is now in.

If you find the PK dots are too visible, see http://www.paulroark.com/BW-Info/Eboni-4-Plus.pdf for the approach that uses a lighter neutral ink also.

Thank you Paul

I was thinking only for QTR and forgot the epson driver.

In your experience how is the PK ink you need for a quite neutral print? 

The eboni 6 print warm in the light and more in the midtones. I'm thinking to try to use about 60-70% ebony and 30-40% PK in the midtones (and 10-20% in the light).
I think that in this solution I will not have problems with PK dots. 

In your experience is enough?

Thank you

Marco
