I am printing an A5 booklet with 36 pages. I am doing a test print as a saddle stitch booklet. One of the spreads has photographs that span out over 3 pages so it is a fold out part. I have no idea how to imposition this with the additional 3 page spread. I thought somehow I could print the 3 page spread separately on an A3 page but that would mess up the multiples of 4 in the publication if I removed it.
