the same replacement width as other hairlines.
Font characters and patterns can be used in a variety of contexts in the same document (for example, different
magnification values), so changing the line width may produce unexpected results. Check the results if you select these
options, and adjust your selections as necessary.

Transparency flattening
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
transparency. 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.
