Please supply your perfect bound booklet as 2 PDFs.  We require a two page PDF with the outer cover and inside cover set as spreads with the spine included, and a separate PDF with the inner pages running in order from start to finish.  For example, an 80 page booklet will have a two page PDF containing pages 80, 1 and 2, 79 set as spreads and a multi-page PDF running in page order from page 3 to 78. The total number of pages must be divisible by 4. We recommend you avoid content which crosses two adjoining pages.

Creep

The closer to the centre pages of a booklet, the more has to be trimmed off the page edges. While our imposition software makes allowances for this, it is not recommended to have text or images too close to the edges of your booklet pages. We recommend a gap of at least 5mm on all edges and that you move all important content in from the binding edge by 10mm.

Spine Width

Calculate the spine width by using the spine width calculator on the Perfect Bound product page.
