Your suggestion is the best one that works. Display an image area that
looks 18 0ray for you, and take the metering from there. I've almost
always observed that this setting gives the best results compared to -/+1
EV adjustments. Obviously 1/30 is the limit, but it is so close to the
refresh rate that some parts may get exposed by 2 scans, while some are
exposed by only 1. In this case, the intensity ratio is near to 2. To
avoid this annoying look, try something like 1/8, or so. In this way, the
intensity difference in the regions will have a ratio nearer to 1.
There are nice photo-like printers, though. Have you tried them?
