Printing and saving transparent artwork
About flattening
If your document or artwork contains transparency, to be output it usually needs to undergo a process called
flattening. Flattening divides transparent artwork into vector-based areas and rasterized areas. As artwork becomes
more complex (mixing images, vectors, type, spot colors, overprinting, and so on), so does the flattening and its
results.
Flattening may be necessary when you print or when you save or export to other formats that don’t support trans-
parency. To retain transparency without flattening when you create PDF files, save your file as Adobe PDF
1.4
(Acrobat 5.0) or later.
You can specify flattening settings and then save and apply them as transparency flattener presets. Transparent
objects are flattened according to the settings in the selected flattener preset.
Note: Transparency flattening cannot be undone after the file is saved.
