Trim objects extend to bleed
This check confirms that images used at the edge of the page extend all the way to the bleed area.
The printed pages of a book are usually trimmed down from the larger sheet that they are printed on as part of the production process. This process can have a tolerance of a few millimetres and so guidelines are build in to prevent any unsightly errors.
By making sure all image that are outside of a ‘safe area’ of 4mm away from the edge continue off the page all the way to the bleed guide we can be confident that ‘bleed images’ will not appear with unsightly white edges.
This check looks at the position of the graphics that extend past the ‘safe area’ and highlights images within 4mm of the page edge that don’t fully bleed.
Fix this problem by moving images within the safe area or extending to the bleed area.
