Easy enough to check. Sometime in the next couple of days I'll build an 
image contrived to generate moiré patterns and I'll report on the 
results via a C80. The inking may be stochastic, but there is still an 
underlying grid - otherwise you could never get a nozzle check with 
straight lines. That said, I think it will take a _very_ contrived image 
to force a moiré pattern with the current drivers.
