I think many piezography users are always living on the cusp of “new technology” which requires frequent changes in documentation. As a scientist I can respect that. I think that IJM could use two manuals for piezography. One “Basic Piezography” that would describe the basic workflow for K7, P2, and DN. I would keep the “Basic Manual” at 1 curve for each paper and say they’re adequate for all ink sets. It’s unclear to me whether P2 can get away with one curve for each ink set as well. I suspect that basic beginner results could be achieved this way, but I may be wrong. DN sounds kind of advanced, so maybe that shouldn’t even be in a “Basic Manual”. The “Basic Manual” should clearly direct the user to curves. I would hope this link would be located on the webpage that sells the ink. Note that IJM provides easy access to profiles for their colour inks, although it used to be easier to see the link. It does exist though. I would hope that a link to downloadable proofing profiles would exist side by side the curves for QTR.
I’m not trying to tell anyone how to do his job here, although I suppose it may sound like it (sorry if it does!). I can see the gaps that Brian is referring to, but I think some of the gaps are related to more advanced topics. At a basic level, one profile is good for all ink sets for a particular paper. This probably wasn’t explained in the original NPM because, at the time, P2 wasn’t described in the manual, so there was no such confusion. Now we have P2 with separate profiles for each ink set which has created a knowledge gap.
Walker has a huge mountain of work to do there. It’s kind of too bad that piezography technology developed with little attention to documentation for quite a few years. I’m sure it has been exciting to be developing all the new ink sets, curves, methods, and so on. For those who have been using Piezography for years and kept up with the changes, it’s been no big deal. For some one like me that has come into the art form at this time, I am really appreciating the help I’ve been getting on this forum from Walker, Brian, and others. Perhaps Brian should be compensated for his help here on this forum. Make sure you pay him in US dollars! I already paid him more than just an arm or a leg, I gave him a head! (OK, a dead, defunct, printer head, but a head nonetheless.)
Keep up the great work Walker!
