OPI XTensions software
OPI XTensions software provides enhancements to the Open Prepress Interface (OPI)
features that are built into QuarkXPress.
In an OPI system, you manipulate low-resolution versions of pictures in QuarkXPress, and
then the high-resolution version of each picture is swapped in by a prepress system or OPI
server at output. OPI requires a layout to be sent for output to a prepress system or server
that can interpret OPI comments and that has access to the high-resolution versions of
pictures targeted for OPI.
Targeting an imported picture for OPI exchange
You can enable OPI on a picture-by-picture basis when you import a picture, when you
modify an imported picture, or when you use the OPI tab of the Usage dialog box (Utilities
menu):
• When you import a picture (File > Import Picture), check Use OPI to enable OPI
substitution for the picture.
• Select a picture that has already been imported into the layout, and then choose Item >
Modify and click the OPI tab. Check Use OPI to enable OPI substitution for the picture.
• Choose Utilities > Usage > OPI tab to display a list of all pictures in the layout. If a picture
is checked in the OPI column, that picture is set to be exchanged.
It is important to avoid renaming picture files when working with pictures that will be
substituted using OPI.
Activating OPI for a layout
When a Print layout containing OPI comments reaches the stage for final output, you
must make sure OPI is active so QuarkXPress will write OPI comments in the output stream.
Even if all appropriate pictures are targeted for OPI, QuarkXPress will not write the OPI
comments unless OPI is active for the layout. However, in a proxy file environment, where
the proxy file themselves contain the OPI information and do not rely on our comments,
OPI need not be active.
To enable OPI for a layout:
1
Choose File > Print. The Print dialog box displays.
2
Click OPI to display the OPI pane.
3
Check OPI Active.
4
Click Print.
