The layers in layered PDF files do not correspond to layers in the
version plan. The following types of layers are available in layered PDF
files (Acrobat):
●
Base layers—contain base content (This is the same as the base
layers that are used in the version plan.)
●
Version change layers—contains the content for each version
excluding the base content. In other words, a version change layer is
a combination of all change layers for a version.
For example, you would see the following layers for the retail catalog
scenario.
EngEast
EngWest
EspEast
EspWest

Figure 23: PDF layers in Acrobat
By default, the layered PDF page opens in Acrobat showing only the
error layer (if any) and the base layer. To see the version change layers,
select the check boxes beside the corresponding version change layer.
Multiple base layers in Acrobat
When you have more than one base layer in a job, each base layer
appears as a separate layer in Acrobat. For example, you are able
select the following layers in a layered PDF file (in Acrobat).
EngEast
EngWest
EspEast
EspWest
Base2

Figure 24: Multiple base layers in Acrobat
Important: Often, you will not be able to see two or more base layers at a time
because one will entirely cover the others. Ensure that you have selected only one
base layer. If you select two base layers to view, the base layer that is listed first in
the layers tab appears on top.
In Acrobat, version change layers are grouped according to their
associated base layer.
