Hi Neil,

Thanks for taking the time to respond, although the 101 on how to prepare 
bleeds wasn't necessary.

My question is more How to communicate your "trim" intentions with the 
printer? Or even: Let's compare how I communicate to my printer with how you 
communicate with yours.

Over the course of the last few years, and the couple of dozen books I've 
prepared, I've usually had to prepare a special diagram showing the distance 
from the end of the text line to the edge of the page, plus the distance to 
the top edge, etc., which I send to the printer, or plate-maker.

I have occassionally tried simply to enable the option in InDesign to add 
crop marks when creating the PDF. However, the printers tend to tell me that 
this isn't helpful. Not sure why not? I don't have any experience with 
imposition software, but I would have thought that adding crop marks to my 
page would be the simplest way for them to know how to place the page.

I've had some experiences where I took care to design the book with 
non-symmetrical margins. I added crop marks, sent the file off, and got a 
proof back with symmetrical margins. Printers seem to assume that margins 
are always symmetrical. How do I, or you, convey most simply to the printer 
what the margins should be? (I'm thinking here of a regular book with just 
text.) I don't know if you do much by way of 200+ pp books, but presumably 
the principles are the same whatever the content or length.

Thanks,
Ariel
