Here is a graphic which illustrates what happens when you do an idential enlargement on pixel generated and vector generated circles.
The pixel generated graphic goes all blurry and not too nice at all. The vector one however stays crisp and clean.
Now imagine you want your logo enlarged 20 times and put on a banner on the side of a building. Which format would you want your logo to be in … pixel or vector?
Any logo we develop is always generated in the vector format so it will perform however you want to use it.
