Digital BW, The Print

I say this in jest, well partially in jest:

If you could make infintesimly small dots and can place the at 
infinitesimly small distances, you could make perfectly dotless 
prints with only the back ink.  And the prints would be perfectly 
smooth if you have a good profile.

Till then.............
