Did you solve the problem? I get different results (banding) with different images with DTP. A consultant says that the printer uses different nozzles with different resolution for different jobs (images), maybe that explains something if QTR can't choose the resolution of the print in the printer if the print is on different heads on different jobs? I use scp7000 (same as scp 6000?), QTR, Print Tool on DTP and two steps with Toyobo GR or KMGT 73 with own media profiles.
