Do it manually....
There's a sample script that installs with ID that will add crops around a selected object to help you.
I saw one post earlier in the forum that suggested File > Print Booklet... and choosing 2-up consecutive... which gets me close, but I couldn't specify the Layout to be on Letter paper.
Thanks for the quick response Peter.
So, my artwork doesn't have a 5x7 bounding box... I suppose I could place a white, or 0% opacity, rectangle behind it and then duplicate that on a Letter-sized page...
I'll give it a try.
I'd place the original file as two pages into a new lettersize doc. That will give you the bounding box you need, and if you have to edit at some point you can edit the original and update the link.
I was hoping there would be a way to specify 2-up on letter with crop marks on export, but... manual isn't too difficult.
This was my solution to the printing front/back. "Windows > Utilities > Scripts" and then "Application > Samples > Applescripts > CropMarks.applescript" allowed the option to add crop marks to either every single object selected, or to the entire group of things selected.
I tend to center such layouts, myself, but I don't see that it matters since you've got it properly mirrored.
For duplex printers, the two pages is a good solution. For printers that print only one side at a time you might want to put both pages on the sheet, head-to-head or foot-to-foot, so you can print as work-and-turn or work-and-tumble, printing a stack on one side, then flipping the stack and running again. This can also be a lot faster on may printers than having them turn each page individually.
Yeah, this is a one-time run of about 50, and it's going to be handled by Kinko's... trying to make it fool proof as much as possible. I'm not sure how they'll print it (duplex, or single page at a time). If I was going to be doing a lot of these, I'd dive in to a deeper, more dynamic solution, but... who has time for that these days!
