There are lots of labs who do this and they all suck if you're going 
to 35mm.

The technology that goes from digital to film is call a film 
recorder.  ALL film recorders exhbit spot-blooming.  I've sent out 
calibrated test images to various labs - both mail order and local 
pro custom labs - and the highest resolution I've ever gotten back 
from a "4000 LPI" film recorder was 1200 PPI.  The highest I've 
gotten back from an "8000 line" fim recorder was 1700 PPI.

The good news is that the film recorder resolution doesn't get any 
worse if you go to higher formats.   So people who want to go 
digital to film without sacrificing resolution can output to 6x7 cm 
or 4x5 sheet film.
