I can't help with your color proplem -- don't know the printer -- but you can use a script to impose your booklet in a new file, then export that to PDF.
The two I use are by Dave Saunders. The first, http://pdsassoc.com/downloads/Buildbooklet.zip merely shuffles the pages in a new file. You then export that as spreads. It's very fast and easy, but cannot handle objects that cross the spine.
The second is at Dave's CS3 Booklet Script and works by placing pages into a new spread-size document. This one does do cross-spine objects, but neither one handles creep. It's been awhile since I used either, but I think bleeds may be an issue for the second script, too.
There are also imposing plugins for Acrobat...
Thanks Peter, i'll give them both a try.
On a different note - do you know much about how indesign handles it's color management? If i turn all color management off through edit>color_matching>emulate..off , do i then lose the images imbedded profiles when they're passed on to the printer? I hope not.
You can't really turn off color management in any modern version of ID. The Emulate CS2 setting essentially tells ID to assume everything is in monitor space, I think, or in the current working spaces. all profile information is isgnored, and (just guessing here -- I never use that setting) it won't get passed to the printer in any way.
You didn't mention your version of ID, but there was a period of time when the monitor profile was introduced into the conversion (incorrectly) if I remember correctly on Mac systems. Being a Windows user I didn't pay a lot of attention and I don't know if the bug was ever resolved, or whether it was specific to one version or to the OS, though I think it was. There were some workarounds provided here at the time, though, so you might find some old threads with useful information.
Thanks again for taking the time to respond, Peter. You've been quite helpful.
I've actually managed to get really good results with '"emulate indesign 2.0 cms off" in combination with printing as a bmp (vs. transperency flattened) and having canon apply the icc profile for the paper. I'm going to read a bit more into it to see what's actually happening on a technical level - let's see if it's what i imagine it is. Ideally the image is just being passed through, from the source to the printer. We'll see.
Thanks Rob - i'm trying the your settings right now - indesign: AdobeRGB and canons colorsync with the appropriate icc.
