Digital BW, The Print

Tom,

 

The initial comparison I was making where I saw the shadow detail
differences was between the 2400 K3 and the custom B&W inksets I have in the
220 (UT-3D) and 2200 (now 5K+cm).  So, there were different drivers.  The 3D
uses the 220 Epson driver but with curves, etc.  With the 2200, I use the
IJC rip.

 

The comparison you might be referring to was another one where I looked at
the 2200 workflow with and without the "LLLK" (a 1:2 dilution of LLK).
There the only difference was the super-light LLLK either being in the mix
or not.  Oddly what was barely noticeable at the closest viewing distances
(actually with a magnifying hood) was not smoothness but slightly better
detail in the one with the LLLK.  I think aside from this type of
unrealistic comparison, the use of that 7th spot for a yellow or other ink
might be more productive.  I suspect the use of yellow to control brightened
paper highlights and borders, not to mention making about any sepia tone one
would want, has substantial potential.  Some might also prefer to have Glop
or R800 Red in that spot.

Paul -

"...When I initially did a visual comparison of a different file, I felt the
shadow detail was the main difference between the K3 and quad images. ..."

Why would there be a difference in shadow detail between K3 and K4? It seems
that the difference would have to do with linerization/profile/driver since
the inks that produce the shadow detail should be the same in both sets.
