This is a screen display issue in Acrobat, which can be seen in PDFs authored in different tools. When you print the PDF, line thickness should be consistent.

For more details, see my article at <http://www.planetpdf.com/creative/article.asp?ContentID=6503>
(specifically under "Inconsistent Line Thickness" and "Line Thickness Comparison").

Acrobat's display was improved in recent versions, but the problem may still be encountered.

Possible measures to reduce the likelihood of the thickness inconsistency are using thinner lines (eg redefine "Very Thin", which is usually 0.25 pt; minimum thickness in FrameMaker is 0.015pt), and having default display magnifications that are multiples of 50%.

In Acrobat/Reader, Preferences, Page Display > Resolution: best display results are when "Use System Setting" is selected, rather than custom resolutions.
