QTR-Quadtone RIP

I don't know if this is relevant to the discussion, by LFN has been  
around for many years and has always been touted as "low foam".  (An  
old timer/pro told students at Ryerson in Toronto in the late '70's  
that "LFN" stood for "Low Foam Non-ionic". He thought it was great  
stuff in film developers.)

Given problems with bubbles and foam in cartridges, that might be a  
helpful property, assuming it works in inks the way it works in  
developer.

Yes, some well-respected photographers recommended using it in the  
developer too, to cut down on foam. It was supposed to be "non-ionic"  
has hence not affect the chemical action of the developer. It did seem  
to help with Kodak HC110, but other wetting agents might have worked,  
too. I never tried any others in the developer,  although photo  
students were often warned to be careful to rinse all the PhotoFlo off  
the reels before loading another batch of film.
