These, as well as the bleed, are set per Print section, as follows:
l
On the Resources pane, right-click a section in the Print context and click Properties.
For the page size, click the drop-down to select a page size from a list of common paper sizes.
Changing the width or height automatically sets the page size to Custom.
Margins define where your text flow will go. Static elements can go everywhere on a page, that
is to say, within the printable space on a page that depends on the printer.
The bleed is the printable space around a page. It can be used on some printers to ensure that
no unprinted edges occur in the final trimmed document. Note: Printers that can’t print a bleed,
will misinterpret this setting. Set the bleed to zero to avoid this.
Tip
By default, measurements settings are in inches (in). You could also type measures in
centimeters (add 'cm' to the measurement, for example: 20cm) or in millimeters (for
example: 150mm).
To change the default unit for measurement settings to centimeters or millimeters: on the
menu, select Window > Preferences > Print > Measurements.
Whitespace elements: using optional space at the end of the last page
Print sections with conditional content and dynamic tables (see "Personalizing content" on
page326) can have a variable amount of space at the bottom of the last page. It is useful to fill
the empty space at the bottom with transpromotional material, but of course you don’t want
extra pages created just for promotional data. 'Whitespace elements' are elements that will only
appear on the page if there is enough space for them.
To convert an element into a whitespace element:
1. Import the promotional image or snippet; see "Images" on page265 and "Snippets" on
page279.
