I had the chance to exchange some emails with one of engineers at HP who designed those curves for alternative processes. Their job is great, for me the best of best one can find out there in what respects to making contrast curves and linearization. I had started it out first with Dan Burkholder's and then with Mark Nelson's PDN systems and found myself sunk deep in the ocean do awkwardness. And also saw that in both of cases prints came with kinda compressed medium tones and washed whites/highlights. And all this after a very hard work trying to figure and interpret stuff coming out of scanner working as a spectrophotometer or even a spectrophotometer itself. A real pain in the ass. Then a friend of mine got a HP Z3200 and I had the chance to give that a try: how lucky a man I turned since then ! The evil printer did almost all of the job by itself, even the contrast curve done with its built-in spectrophotometer, and so well done. Then I found myself coming back and forth to my friend's workspace, a pain in the ass. Then I was back to my old Epson trying to resemble that the 3200 was capable and found no way, my Epson inks weren't blocking UV enough. I am now working with an HP but the z3100 because they block UV and actually found out another system for making the curves up. It's called Chart Throb. They work great and calibration is a piece of cake Sent from me > On Apr 20, 2014, at 11:53 PM, Richard Man <richard at richardmanphoto.com> > wrote: > > I know a number of people doing "alternative processes" (ancient > resurrected processes?) and they all use Epson.
