Print setup

The trim line is where your lab cuts. Push image content past it so a slightly off cut never shows white. The green safety margin is the opposite - keep anything you can't afford to lose inside it.

Hide bleed and the canvas shows one to one what's expected to come back from your lab.

T toggles the trim line, M the margin line, and Shift + B cycles the bleed display. The bleed, trim and safety controls are also available in settings.

Vendor books lock trim to the vendor spec. In a custom book you can move the trim and margin lines yourself, in settings.

Print vendor info shows the spread size, bleed, safety margin and DPI BookProofs is using for your book. Worth a look at the start of a project - and let us know if your lab has changed anything by sending an email to support@bookproofs.com.

On book projects, rounded corners and rounded image borders that would land in the trim area automatically stay square, so the export matches the finished print.

The template editor keeps its own view settings, so the trim, margin and bleed lines you have showing on the normal canvas change by default when you go in to the template editor. Turn this on and they carry straight through, so you keep a consistent view between normal design work and template editor as you work in either mode.
