I needed to use a feature that I thought was there, but aparently removed. Export Comps to PDF is not in CS5. Aparently I hadn't used it in a while because it is gone from CS4 also. In efforts to get the same desired effect, I played around with using the Bridge output and wasn't happy with the results. Not happy with it at all. I Exported individual comps to PDF and then went to Bridge output and put them out to a PDF, my beautiful fonts that were present in the PDF's were thunked down to ugly JPG's. Plus Bridge insists on adding an extra margin even though I have margins set to “O”.

Next try:
Export Comps to JPG high res, place in Power Point, export to PDF. FAIL. Ugly JPG artifacting.
Attempt 3:
Export Layer Comps to files using PDF Format,
In Acrobat, combine all 18 separate files into one.
Optimize PDF
Result: PDF looks good, but is 83 MB which is crazy huge for an 18 page PDF and can't be shared on the internet.
Attempt 4:
Start a new 18 page project in InDesign.
Place the PSD on every single page and the master.
Go through the pages and turn only the layer on that I want, including only the background on the master page
Export to PDF
Result: PDF looks great, and it is only 1.1 MB
That is the long way around, but probably gives the result that I would expect from Export Comps to PDF.
Now, if could somehow find a way that InDesign would automatically place each Comp on a different page, or find a way to do this faster than going in to each and every linked PSD and turning layers on and off, I would be set to go.
Is this possible?
