I have a feeling they haven't a clue in many cases.

You're spot on here, actually. A few months ago I wangled my way into the 
upstairs work area where the plate-maker was working at his computer doing 
the imposition. He explained that my crops marks are not useful for exactly 
the reason you say. So that's something confirmed. But he still requested a 
schematic diagram with measurements for the margins.

I also cross-examined him regarding creep. He said he has heard of it 
(great), but never uses it because too often his creep creeps the wrong way. 
Hmmm.

It's very useful, thank you.
