Stroke weight different when output to PDF

[lnivin]

Our customer has InDesign CS1. Text has a .25 pt stroke. The PDF created from this file has a .5 pt stroke.

I was able to recreate using InDesign CS3. Seems like this is the default.

In InDesign CS5, I could recreate if the new document was designated for Web instead of Print.

Anyone seen this?

Is there a way to retain the stroke weight in CS1?

Thanks,
Linda

What is the resolution of the PDF? For some PDF specifications there is a limit to how fine a line may be. "Hairlines" are printer resolution dependant.
(But at 300ppi a stroke 0.24 pt is one pixel, is your PDF setting assuming 150ppi or less, if so that would explain the 0.5pt limit.)

Also a little curious how it is created, is the text still text? InDesign places the stroke outside text, so as not to distort the letter forms, this may mean that in CS1 the PDF has a stroke double that of the stroke applied, since there is now "outside path" feature, but the net effect is a .25 pt stroke (as long as the text is filled with another colour)

When you say recreate, you mean recreate the "error" of a thicker stroke?
Also check in acrobat what the setting for Page display "enhance thin lines is set to"

(command/ctrl 5 is also an interesting command to hide stroke thickness.)
