Sorry to be thick about this.  

I'm going to try my hand at mixing up the carbon 6 ink set and working 
on my R220 this weekend.  I think I've gathered up all the components 
needed.  My question is about the photoflo.  I've purchased a bottle 
of "Photoflo 200."  Am I supposed to use this straight out of the 
bottle or dilute it down prior to mixing up my clear base? (For film 
use, instructions say dilute 1:200...)

Thanks,
Earl
