Digital BW, The Print

Martin,
   The fading black is subjective.  Initial PT Sel prints blew away 
FS-N prints from same negatives in the blacks; after several weeks, 
comparing the same prints was more of a standoff in the blacks.  
Bright room, no sun.
 
   Maybe the very light nozzle check lines in the "yellow" postion 
and blanked out 0% to 20% in stepwedge is a clogging problem.  It did 
improve when I tried Jerry Olson's patent remedy of squirting a 1:9 
ammonia:water mix on the heads (after many cleaning cycles, etc., as 
recommended), but the same problem reappeared in two days.   Not an 
expert on clogging (I've been lucky), but this does seem ink related -
- I thought most clogs turned up as gaps in nozzle check or no lines 
in nozzle check (neither here) or microbanding (ditto).

    As for going to a CIS, I'm persuaded.  Had been deterred by my 
relatively low volume and horror stories of the "greenies," etc.  Can 
you direct me to the best tutorial on setting up a CIS system and 
keeping it running?  Are the Niagara CIS systems as good as any?  
Thanks.
