Might it be related to exhaustion of sulfite and/or hydroquinone in the 
developer? What if a fresh bath of developer is used for each print? What if the 
developer is replenished with a fractional amount of fresh stock added each time?

I don't recall every bit of strange results, but I did find frustration with 
unpredictably variable outcome from two successive prints. That's why I 
formulated a lith print developer that is fully active and well seasoned when 
freshly mixed, so that it can be used one-shot.

I don't really have a explanation for this phenomenon. But one thing I am 
curious about is whether these flakes are a result of inhibited development or 
bleached latent image. It'd be curious to take a sample of partially lith 
developed print with the artifacts and bring it to a fresh bath of regular print 
developer to continue development. If the latent image is busted you'd expect 
the flakes to remain undeveloped.
