Cross-plane screening helps most at very low densities (highlights).
The placement error is constant (it doesn't depend upon the density).
So if the placement deviation is on the order of .001", but the
separation between dots is 1/64" (which at 1440x720 DPI corresponds to
a density of about .4%, which is certainly quite visible), the
placement error is negligible compared to the average dot separation.
Good point. So to use this type of screening in the real world, it would
be desirable to
have the different color planes screens de-correlated once the dot
density grow high enough,
thereby getting the benefits in the highlights where it counts, without
triggering banding and pattern
issues.
