Digital BW, The Print

I am re-reading "Real World Scanning and Halftones" now that I have 
recommitted to doing some printing digitally.  Currently on Ch. 6 
p85 ;-)

Again, the equipment I'm using is an Agfa DuoScan (transparency & 
reflective) which if I remember has a maximum _optical_ resolution of 
1000x2000 SPI - and then printing to an Epson 3000, 1440x720 DPI.


I have never understood to my satisfaction what level of scanning 
would be 2x (& I understand lower is ok to about 1.5x) the level of 
the Epson printer.

It was also interesting to read that if the middle tones are 
consistently mucking up, it may require a better quality scanner.

Virgil, I summon thee, come to the shores and lead me 
through...Linotype-Hell <g>
