Re: Lightroom and QTR for Windows -- advice for an export for QTR strategy

2016-11-15 by brian_downunda@...

Mike, the question is not whether it works at all, since they're both 6 channel printers, but how well does it work? Do QTR curves from the 1430 print much the same on the R280? That's the magic question. I could use 1430 curves on my R1900 (with some adjustments to the .quad for ink placement), but the results were a very long way from linear.

On Print Tool, it would be better if it was answered by someone who uses a Mac more often than I, but my understanding is that if you print from PS direct to QTR and the image either has no colour space assigned or is in Grey Gamma 2.2, then the OS X print pipeline will do a hidden profile conversion en route to QTR, which will change the print from what you're expecting. Print Tool doesn't do this.

Thank you for your response, Brian. It prompted me to experiment a bit, and I was able to install the 1400/1430 files into the QTR area for the R280 printer. I copied them into the QTR/Profiles/R260-R380-1400-MIS folder and then ran the Install R280-MIS.command file that is within that folder. I can print using those profiles from the Mac QTR Photoshop print process or through Print Tool. I have seen recommendations that printing through Print Tool is the better choice, though I don't fully understand why that is so.
