Saving PDF as TIFF/PNG - Where did anti-aliasing go? No Smoothing.

Hey all,

I'm using Acrobat XI (v 11.1.07 - CC on Win7 64 bit) and trying to Save As... a TIFF or PNG.

The output has no antialiasing or smoothing.

When did this happen?

It makes this feature completely useless.

Can anyone suggest a way to get a good result?

Thanks,

Anthony
