So would it look better at 360 then?
Not having to resample?
Wouldn't it be faster or better?
Then having file be 300 or 240?


To me if I have a 360 printer then why not feed it 360 images?

Certainly not higher.
And certainly not 259!


And I like the idea of having a ppi for every degree in a circle.
Day in the year....
