Marco,
Even Creo Spectrum CTP, for example, which doubles as a CMYK dot proofer,
cannot make proofs using the same exact dot as on the plate, because of
needed color adjustment on the proof to match a certain press condition. And
I must say, some prepress houses are adamant about showing dot on their
proofs to their clients, especially in the garment industry where, as was
noted here, moirés naturally occurs. For those prepress houses, contone
proofs are not an option, unfortunately.
BTW, I was told that stochastic printing completely eliminates any possible
moiré. Can anybody confirm that there is any truth to this?
