Issues exporting sketched splines to PDF

Ladies\Gentlemen,

I'm having issues exporting drawings with sketched Splines to PDF drawings.

My problem is when creating sketched splines in drawings they look smooth in SolidWorks 2014 but as soon as I export them to a PDF they look jagged and serrated.

Any fixes or setting I maybe missing to smooth these splines?

Thanks,

-Charlie
