In either of the following situations, you must specify either the art box
or trim box.
●
Page box layout does not conform with press layout
●
Layout has no crop box or crop box is equal to media box
The art box defines the extent of a page's meaningful content. If you
are using only part of a page, the art box is the area of text, pictures,
and needed white space. The rest of the page, which is blank, isn't
considered.
If you are using the whole page, then you must specify the trim box,
media box, and the bleed box. If the bleed box is not already defined,
you can specify that the normalizer function set the bleed box to be
equal to the media box.
Press layout specifications:
●
The outer box must be the media box.
●
The bleed box must be inside or equal to the media box.
●
The trim box must be inside or equal to the bleed box.
●
The layout has no crop box or the crop box is equal to the media
box.
