RE: piezography K7



Hi Bill. I've been using K7 inks on my 2100/2200 for a few weeks now and the 
results are not very good.  If you are used to printing with Piezotones and 
Studioprint RIP with Portfolio Black you will be very very dissapointed. 
Deffinatelly not worth changing from the set up mentioned, to K7. My prints 
actually look worse! (unless I'm doing something wrong???)

There is only a SLIGHT increase in tonal range and a SLIGHT increase in 
smoothness. The dmax is actually worse. You can get the same Dmax with the 
first generation Ultrachrome inks! Just goes to show that 4 blacks was 
plenty to match a silver print (on matte paper). Seems as though K7 is a bit 
of a gimick. Just my experiance anyway, again I could be doing something 
wrong? How is everyone else finding it out there?


Thanks, Benny.

I also think that 7 grays are probably not necessary for most  
applications and any smoothness gains would be hard to detect on fine  
art papers.  I'm using 4 of the neutral k7 grays (including the  
black) and the carbon sepia inks in a dual quad setup on my 4000,  
driven by QTR.  I'm very pleased with the prints from both inksets.

Hi

I would agree. I have been using K7 for about two
weeks and the most important failing for me is D Max.
The darkest step on the 21 step file measures 1.4 on
Photo Rag 308 which is rather pathetic compared to
every other ink I use. (UC, Eboni etc)

I must admit though that there is very nice
transitions from step to step with the result of a
finely graded tonality which is very pleasant to see.

I am going to keep working on the DMax issue by
playing with the QTR controls but for now K7 is simply
experimental for me.
