My fonts are blurry upon export

Hi all.  While I'm in CorelDraw my fonts look nice and clear, but when I export my project as a png the fonts are blurry.  I thought maybe it was because I used a script font and that made it hard to read, but I changed the font to Century Gothic and it is also coming out blurry.  Any ideas why I'm having this problem?

Appreciate your help
