QTR-Quadtone RIP

Joe, I just started using the NK7 inks in a 2200. I had some feedback
from a customer that seems similar. I made a sample print for an
artist from a scan of his pencil drawing. I provided QTR samples made
using K2 inks (K and LK) and K7 inks. I have been working with him for
quite some time, trying to match my print tonality to his original. He
of course preferred the K7 smoothness but also noted that the
transition in the lightest highlights seemed abrupt. He did not see
this in the K2 print. Much of the tonality in his drawing falls into
the midrange and highlight areas btw. I have not noticed this in my
photos yet, but that may be because I have not printed an image that
hits this the right way.

You could play with the gamma slider but I doubt that would help. I
think your only option is to create your own curve. Might be a bit
tricky, given the number of inks and the need to have the cross overs
carefully defined.

Let us know what you end up doing.

Terry.

Has anyone else made
