If you must use Acrobat 4.0 compatibility, your document contains spot colors, and you want to create a PDF file
for on-screen viewing (such as a client review), you may want to select the Simulate Overprint option in the
Output area of the Export Adobe PDF dialog box. This option properly simulates the spot and transparent areas;
recipients of the PDF file won’t have to select Overprint Preview in Acrobat to see how the document will look
when printed. However, the Simulate Overprint option converts all spot colors to process color equivalents in the
resulting PDF file, so be sure to deselect this option when you create the PDF for final production.

Consider using the predefined [Press Quality] Adobe PDF preset. This preset contains flattener settings appro-
priate for complex documents intended for high-resolution output.
Trapping
Flattening may convert vectors to rasterized areas. Traps applied to artwork in Adobe Illustrator using strokes and
placed in InDesign will be preserved. Traps applied to vector artwork drawn in InDesign and then rasterized may
not be preserved.
To keep as many objects vector as possible, select the [High Resolution] transparency flattener preset in the
Advanced area of the Print or Export Adobe PDF dialog box.
