I've created these flash cards in illustrator where the artboards measure 9 centimeters by 9 centimeters (that's about 3,5 X 3,5 inches for our American friends). Now when I export by artboards in Illustrator (CS6) I get asked at what resolution I want to export them, options being:
- Screen (72 ppi)
- Medium (150 ppi)
- High (300 ppi)
I'm not too sure what option to choose. All I want is that when I print these puppies that they'll be 9cm X 9cm and that it'll look as crisp as possible. I have no experience in print and I would really appreciate some help with this. Thanks!
