We need a lot more detail...
Version of ID? OS? What is the Document Intent and the size set in the Document Setup dialog?
What is the nature of the project? What sort of output are you trying to make, and how do you intend for it to be used?
I have cs6 ID. OS X
Document is an A4 booklet with saddle binding printed on A3.
I set the document on an a3 portrait.
I need a pdf as final so it can be send for print
If I export the booklet in A4 printing size(means A5 booklet) and use distiller for the pdf it works, but is not the size that I need.
Am sorry if this is confusing it is for me also. I haven't done any printing work for years
No, send a regular PDF in single pages using File > Export... (ask them what settings to use). This one PDF file with all single pages in consecutive order, unless they specifically requested you send spreads (in which case you should consider finding another printer).
To get the Print Booklet dialog to five you the correct options for printing to postscript you need to install the ADPDF9 PPD file (see InDesignSecrets » Blog Archive » Acrobat’s Adobe PDF Printer Replaced in Snow Leopard and read the comments for where to install it). You may download it from me at Download - Hightail
If the printer cannot give you settings for export, the safest bet is PDF/X-1a, choosing your local regional standard color space.
The printer should be your first port of call to find out how they want the file supplying.
In addition to Peter's advice to send them in individual pages in reading order (or indeed, run for the hills if they ask you to do the imposition for them), you'll need to add bleed (probably 3mm on each edge except for the inside). It's likely they'll either be printing your booklet on SRA3 rather than A3. If they're printing on exactly A3, I don't think you'll be able to run those images off the edge of the sheet.
Ah thank you so much guys
Really appreciate this. Will get in contact with my client
Ah, so you're in contact with the client but not the printer? A fraught situation I'm familiar with, on both ends! If it's possible to take the client out of the chain, I imagine you'll get there sooner.
And you're welcome.
Yes unfortunately I am in touch with a very stubborn client that insist on having the final file ready for printing.
Trying to get printer's details so can solve this
