Digital BW, The Print

ok, this seems like a backward question, but how would you spot an 
inkjet print?  Didn't notice 2 spots in black areas in a 8x12" print 
from my 7660... think the driver sharpened them up, but with a 
$3/print cost I'd rather just spot the print... like in the good 'ole 
days.  I have Spotall and a Sharpie pen, which would be better?  
Spotall is water based and the Sharpie solvent based... don't want to 
mess up that glorious gloss surface:)
