This problem is decades old, since the beginning of GrADS, but there
are several work arounds. You don't need to buy Adobe Pro.<br>

Jennifer-the white lines appear when opening the .pdf in Preview
(as you mentioned), but also in Powerpoint and Google Chrome.
Are you implying that the white lines are unavoidable (for a
.pdf) except when using more sophisticated software such as
Adobe Pro and/or those used by production teams in publication?</div>

So essentially to avoid these white lines for Powerpoint
presentations, etc, I should use a .png or similar? The only
headache here is the different looks of .png versus .pdf so this
would require editing the plot specifications when going back
and forth.</div>
