what is the resolution defined for the document? is it fpor print with resolution or digital with pixel dimention??

when you export, use high quality, but first notice your file size and res.

You might be using a file with a low resolution.  It would appear higher quality in PDF,  but the other file formats would look blurry.  What DPI are you using and are you using any vector brushes?
