Vector artwork is preferred for all orders, and required. What is vector art ? Unlike JPEGs, GiFs, and BMP images (raster art), vector graphics are not made up of a grid of pixels. Instead, vector graphics are comprised of paths, which are defined by a start and end point, along with other points, curves, and angles along the way. These paths can be used to create simple drawing or complex diagrams. Paths are even used to define the character of specific typefaces. Because vector-based images are not made up of a specific number of dots, they can be scaled to a larger size and not lose any image quality, if you blow up a rasrer graphic, it will look blocky , or "pixielated". This makes vector graphics ideal for logos, which can be small enough to appear on a business card, but can also be scaled to fill a billboard. Common types of vector graphics include Adobe Illustrator (AI), Corel (Cdr) Draw and Encapsulated Post Script files (EPS), where the file extension are .Al or .EPS .
