Brian, there’s no angst on my part. Awhile back I offered to run your quad file and a 51x3 measurement file through my workflow and send you the results. This was before I even considered offering this as a service. I am still willing to do so, feel free to send me an email at richard@richardboutwell.com.
What I write on here, and on my site, is meant to help people. For people who want more I do offer workshops and one-on-one teaching—the information isn’t very different than what I have posted before, but people are willing to pay to be taught directly, without sifting through lots of information that isn't relevant to them. The personalized relinearization service is the same thing. It's meant to help people who are not able, or simply don’t want, to spend the time and energy experimenting with the tools available.
Roy has made an amazing program that gives people tons of control over their printers and inks and allows them the tools to make better black and white prints. I would continue to tell people to buy and use QTR and PrintTool if they were five times the price he asks people to buy it for. I'm happy he is including Linearize-Quad as part of the next release of QTR, and is making it available for people now.
I tried the new app for a few hours on Wednesday. It seemed to work well once on my computer running Yosemite, and the other times it either just made a “-out.txt” file with a graph of the Lab values (with no error message in the text file it produced), or didn’t do anything when the .quad and measurement files were dropped onto it.
It responded somewhat better on my snow leopard machine though. The new linearize-quad.app seems to work well with profiles that produce a somewhat smooth curve already, but if there are reversals or bumps, then it might not work at all, or it might create a bumpy linearization. It worked similarly well to my method with an Eboni-6 profile that was pretty linear to begin with, but I found the results with my relinearization method were smoother than the results from the new QTR app for existing P2 Piezography profiles I tested (which all print too dark on my 3800, and are a little bumpy). I’m heading out of town for a few weeks and I have lots of client work to do before then, but I will try to make a few comparison scans and post them before I head out.
