    Ideally a profile should be specific to the printing conditions being characterized – because that is what a profile does: it characterizes the printing conditions. “Printing conditions” includes paper, ink, printer and all the attendant settings. When comparing two printing conditions for different profiling techniques/technology, you fix all the printing conditions, the profiling process being the variable, and see what happens. Then you have a valid comparison of differences of outcomes due strictly to the one profiling technology versus the other. You evaluate those differences both by making measurements so there is objective data, and by visual comparison of prints, which is subjective, but to the same observer. So in principle this is totally doable and valid.

    Because all these materials and equipment are manufactured to a high standard of uniformity these days, it could well be that the profiles from a company such as ImagePrint, or from Epson itself, would be very usable on anyone’s printer provided it is in about the same condition as the materials and equipment the company used to make its profiles. They could even be better if the person doing the custom profiling in his/her studio were using profiling technology and knowledge inferior to that of the third party company.

    I do know that targets made and read say 18 months ago, if re-printed and re-read today would give slightly different results than previously obtained. The differences could come from a number of sources through the chain from printing to testing and therefore hard to pin down, but in principle one should not rule anything out until the root cause is established. Whether it’s worthwhile doing so is another matter. It depends on what’s changed and by how much. Instruments, equipment and materials can return different values that are all within their own specs, and very often these differences are not large enough to be disturbing in a real print, as opposed to a target measurement exercise. In fact, there is a range of slippage between what numbers inform us to expect and what we may perceive in the print. I explored some of this in my article “Do the Numbers Matter”, but that exercise too had its limits, because it didn’t get into translating perceived differences between patches to perceived differences of those same colours as viewed within real photographs having many thousands of colours. That could be the subject of “Do the Numbers Matter Redux”, but these exercises are very time-consuming and demanding to put together, so don’t hold your breath waiting for it.

    As for Image Print, needless to say I keep hearing Kevin on the subject of Image Print, but just focusing on the real significance of any profile quality differences, I haven’t tested it first-hand against my own profiles and the Epson driver. I’m satisfied with what I get from the latter, but I’m open to making the comparison if there were a fully featured demo arrangement valid for a month or so to do that.

    I can confirm unequivocally that neither the MYIRO, nor the i1Pro3, nor basICColor Display 6 are infested with cockroaches; if they were I’d be the first to tell you!  Now Kevin’s computer, I dunno….another talk-show  🙂

    I just took delivery of  “Light on the Landscape” yesterday. Clearly I haven’t digested it all yet, but I did look through it rather carefully and read some passages. I am deeply impressed. This book is a treasure of fine photography, fine writing, fine presentation and real inspiration. I highly recommend it. I bought one of the signed hardcover copies. I don’t know how many hard cover copies Rocky Nook had manufactured, but I think this is one book that deserves to be owned and preserved in hard covers. There is a wealth of guidance and insight in it that will be valuable to return to over and over again.
