trapping parameters set in the refine process template. Additional
automatic trapping options are available in PDF Trap Editor.
●
PDF Trap Viewer
The PDF Trap Viewer is included with the purchase of Prinergy. It is
a plug-in to Adobe Acrobat that lets you view traps created with the
automatic trapper.
●
PDF Trap Editor
The PDF Trap Editor is an additional trapping component that can
be purchased separately. The PDF Trap Editor is a plug-in to Adobe
Acrobat that allows you to interactively create, change, and delete
traps. The advanced features of the PDF Trap Editor, such as setting
trap geometry, making keepaway traps, and trap path editing, are
used primarily in packaging.
Trapping using these tools has the following advantages:
●
Resolution independence is maintained
●
Prinergy can do spreads, chokes, and center traps
●
You can view traps in the PDF Trap Viewer plug-in
●
If you purchase a PDF Trap Editor plug-in, you can create and edit
traps interactively
If you need to adjust any traps, you can do the following:
●
Retrap automatically with a different set of process template
parameters
●
Use the PDF Trap Editor to retrap an entire page or change
individual traps
For more information on the trapping tools, launch Adobe Acrobat,
select
Plug-In Help
from the
Help
menu, and then select
PDF Trap
Editor
from the submenu.
Note: The PDF Trap Editor is object-based, so it traps object to object or object to
image. An object-based trapper is also sometimes called a vector-based trapper.
Other types of trappers include raster trappers and hybrid trappers. A raster
trapper traps rasterized data. Hybrid trappers combine raster and vector-based
trapping.
Trapping using other methods
There are other methods and tools for trapping as described below.
However, the content generator (the person creating the document)
does not always know much about trapping, so it is best to leave
trapping to the prepress shop or printer. As such, we recommend that
you trap inside Prinergy using the trapping tools.
If you trap directly in the layout application (QuarkXPress or
PageMaker), the following occurs:
