How do you send a large InDesign documnet as an A3 pdf?
I have an 80Mb InDesign doument covered with text, lines etc on top aof a 150cm x 100cm jpeg.
Before I send this large file to the client he would like to see a smaller version for checking.
Yesterday I stitched together 9 screen saver shots in photoshop to email a jpeg, but this is not the way to go.
I have asked around and sending it via my printer at a reduced size seems the way to go but as I listen to my laptop whiring away like a washing machine on spin cycle for 20-30 minutes I wonder if anyone can give me the step by step simple foolproof answer to this problem.
Thankyou Nick

Create a PDF file from your InDesign work.

Create a new InDesign document sized for A3.

Place the PDF you just created in the A3 document and scale appropriately.

Export your A3 PDF file.
