Hi David.

Thank you very much, I appreciate your reply. I tried placing the pages of the PDF back into a new ID file, but it still takes quite a lot of manual moving. I will try my best to explain how I ended setting it up: 

– I data merged the postcards to create a PDF (1-up).
– Using this postcard PDF, I placed all the pages into my A3 document using the PDFplacer script.
– Since this script places every PDF on its own page, I had to manually move each postcard so that I had 5 cards on every A3 page.
– On my A3 document master page, I created 5 image frames the size of the postcards (3 vertically on the top and 2 horizontally at the bottom).
– For each page, I then rotated 3 postcards to 90 degrees (because there are 3 vertically).
– I then used the swapitems script to replace the image frames with the postcard.

Whew! Hope I didn't confuse you. As you can tell, this wasn't the most efficient way of going about it.

What imposition programs do you recommend? Thanks. =)

Thanks for the reply. I haven't thought about using bridge to check images, and that plug-in from zevrix is exactly what we all need!

Hey Hank, thanks for your reply.

I should actually explain what I mean by 'tabbed booklet'. All page spreads are exactly the same size, except the fold line is different on each spread. When it gets saddle stitched, the booklet forms 'tab like-pages'. Hope this makes sense.

Your method with all the pages rotated 90 degrees works great, but it leaves empty white spaces when I export it because the pages are different sizes. I have tried manually cropping the pages in acrobat, but the tool isn't very accurate. Is there an easier way for this?

Thanks for the help guys, all your suggestions have been very helpful.

If you manually apply character styles with only a 'bold' and apply it to a paragraph style, it doesn't override the paragraph style. I knew there was a simpler way of doing it because I always thought paragraph styles would override the character styles. I have tested it out and it works like a charm!

The advantage of naming the styles in abbreviated form such as 'TX' or 'TXW' is that it is easily seen and simple to remember. But I can also see the problem because only the person who made the document know what they represent. Labelling them as levels may be the option to use to overcome this.
