Can anyone give me some advice for setting up an indesign document for a 100 page A4 booklet?
From what i've seen i need to account for around 7m for the spine.
I'm wondering if i create a new A4 doc with 98 facing pages or should i create A3 documents and mark out guidelines for the spine?
i've few different templates online - all setting up A4 facing pages but i read somewhere that should set up an A3 and create the spine yourself. Would printers accept it all in A4?
Any help would much appreciated!
Set up your document A4. You do not need to accommodate for this 7mm (which is actually referred to as grind or grind off), it is additional space added between facing pages of a print imposition for a perfect binding layout, in which the printer will add this space.
For spine, I'm assuming you want an actual "flat" spine? In this case, when we set up a publication, we create two files; one for the cover at flat size, and include the spine width, and the "narrative" as trim size facing-page document. So for instance, the cover width would be twice the A4 width + 7mm, and the file would have 2 pages, one being the outside, the other being the inside. The narrative pages are self-explanatory, and require no special treatment. Hope this helps.
