Digital BW, The Print

Does anyone have any QTR curves for Piezzotones for an Epson 7000 that I could buy 
from you. I know Roy can linearize printers but I think he is way to busy to worry about 
doing that and I don't have a densitometer.

I sort of have the opposite problem. That is I have a densitometr but 
don't understand how to linearize a specific inkset-printer 
combination. Where does one look for that information.

Thanks,

In the QTR folder open the CurveDesign folder. There's a folder called Eye-One that will 
explain how to linerize with the Eye-One but the info could be used with densitometers 
too.

Roy is King

Just wondering if anyone mighht have a set of QRT curves for the 7600
and MIS UT7 inks and HPR and or Entrada BW they might like to share as
I don't have a way of building my own.

Thanks in Advance

Hi All,

[I posted this on the QTR Group as well but I am not sure how active 
it is so am cross posting it here. I trust that is OK but if not 
please feel free to delete this post Mr/s Moderator]

I am currently attempting for the first time to build some curves in 
QTR for some new papers I am trying. I am using a ColorVision 
measuring device. I am using Epson Ultrachrome inks. I am working 
through Tom Moore's very comprehensive instructions.

I have some questions about the Characterizing the Ink Paper 
Combination process:
1. I assume we are only concerned about the black strip on the 
printout to assess ink limit. Is that correct?

2. My black strip looks very blocked up at the darker end. This is 
confirmed by measurements as follows:
55%	1.87
60%	2.00
65%	2.05
70%	2.07
75%	2.13
80%	2.16
85%	2.20
90%	2.22
95%	2.23
100%	2.23
Based on this data, I am tempted to use a limit of 75%. Is this a 
prudent interpretation or would 85% be better?
 
3. I tried 70% just to experiment and the darkest swatch measures 
2.1 - does mean that if I use a 70% ink limit that my dmax becomes 
2.1 on that particular paper?

4. Assuming the answer to (3) above is yes, is the whole 
characterization process about optimising the compromise between dmax 
and blocked up shadows?

Any and all responses very much appreciated.

Thanks and regards
