I find that the various types of "dot-proofs" are extremely deceptive. True,
in the past, the intent of proofing the dots was to predict moire. However,
most new dot proof devices are postscript driven, and do not have the same
resolution or dot forming engine of the CTP device the file will end up on.
Therefore, they only provide a deceptive dot that DOES NOT predict the
potential moire on the output device. The only proofing device I know of
that give absolute dot prediction is the Creo Spectrum, which can output
proofs and plates on the same device.

Hi Michael.
Yes, I agree that in that case a dot proof makes more sense, given the
unusual destination of the file.
What I had in mind, though, are situations of the more standard variety, say
SWOP (133 lpi, web-coated offset, etc.). In that case, I would find it hard
to say that a dot proof is absolutely and unequivocally indispensable.
