We originally had a plush brush on our machine. It wore out after less than
one year of use, whereas the bristle brush we replaced it with should last
much longer. The plush brush did not work perfectly on plates thicker than
0.040"--it's "bristles" are too short. We were told after complaining about
our experience that the plush brush is intended specifically for processing
fine halftone screens. The alternatives to the bristle brush are made to
hold halftone dots for tones less than 3%. For text or line work, based on
our experience, the plush brush makes no difference. But there are still
sources--we can supply custom plush brushes if anyone is still interested.
I'd be curious about ultrasound. I've also heard of using a pressure wash,
but the tech data sheet for Printight makes this sound like an inferior
option (if I recall correctly).
Hope this helps,
