Digital BW, The Print

Steve,

I haven't printed at some of those resolutions, but I always understood that 
the numbers should be factors of 720ppi, the ppi that the printer uses for 
printing, not the dpi. So 360ppi is OK, as is 240 and 180, but not 480 or 
576. Easy to confirm by printing a set of black and white 1 pixel lines and 
looking for the aliasing patterns. Many give you a lovely 'tartan' like 
print (for those of you who know of Scotland).

I understood good practice to be at least always use a clean factor of the
print resolution ie 2880/4=720, 2880/5=576, 2880/6=480, 2880/8=360,
2880/9=320, 2880/10=288.  The 300 simply came about as a result of the old
2x150lpi (as Bob Frost noted in an earlier post).
