My apologies, but some of the math in my previous message was inaccurate.
Here's what I should have written:

If the platesetter images at, say, 2,540dpi, there is one raster dot every
10 microns (1" / 2,540 = 0.0003937" = 0.010 millimeters = 10 microns), which
also happens to be one of the dot sizes commonly used for FM (stochastic)
screening.

Of course, in such a grid there are 100 dots per linear millimeter (2,540
per linear inch), which translates into 10,000 per square millimeter, or
6,451,600 per square inch: a lot of possible positions within a small space,
practically indistinguishable from what one could call a truly random
distribution.
