Hallo Brian: What I understand is that in your opinion it is better after post processing in LR not to use the printing capability in LR but to export to a print file and print using QI?
After printing using QI what would be the advantage of saving this print file? What does it mean: "leaving the interpolation to QI"?
Harry
I think he meant the "file for printing," not a print-to-file thing. Just saving the file that is going to be printed in a different folder.
As to the interpolation, do not re-size in lightroom. Only crop to the size/shape you want but do not change the ppi--even if it says something wierd like 286.7. QI will handle that part. BETTER than anything else can.
