Why on Earth are you exporting in a raster graphics format?...then export to png file with type optimized anti aliasing...
Open the file in Photoshop. When you get the dialog box to convert it, choose a high resolution... probably 300dpi. After it opens, resize the image to 72dpi at the size you need. It should be much cleaner.
Isn't that the same as just exporting at 300 dpi from illustrator? Your saying open a eps in photoshop? I'd like to do it all in illustrator if possible
old topic but...If I have designed a logo to be printed on a tshirt should I clean it up in photoshop or send it as an eps?
