Since I do not have softproofing profiles that correspond to my QTR profile, I am thinking that I may as well just decrease the exposure slider by a set amount in lightroom before exporting for QTR printing---other people seem to be using curves to mimick this or use a monitor profile with a low cd/m2 value but since I am happy with the monitor settings for online posting it seems like I should adjust the print version of pictures. This seems vaguely dissatisfying though I have to say after all the scientific mucking about I did to get a good QTR profile.
Is this really what cutting edge printers do when using QTR?
