Digital BW, The Print

That is at the pixel level only. 1/300 th of an inch is very small. 
very high quality magazines publish at 175 lpi (which is the realm you 
are entering into).

At that line screen you are effectively (almost) doubling the # of 
tones in both directions for a total of 2.938x46 or 135 distinct tones.
At a line screen of 133 - which is normal magazine res. 5.087x46 or 234 
distinct tones.

Add to that the fact the epson uses variable droplets (I believe 3 
sizes) and even more tones are possible.

Granted the dither pattern epson uses is not a line screen but you must 
be getting the idea that the dithering is not necessarily done on a 
pixel by pixel basis.
