Hello, Michael! I'm preferring the -qh or even -qu profile quality for inkjet printers. But You should use a high number of different test patches for high precision mode. For example, I print about 2700-3600 patches for -qu. There may be a difference: the higher quality mode have more freedom to curve the channels, that's why there may be some strange effects. It may be noticeable when test patch quantity is insufficient for the device characterization at certain region.
