What is a vector graphic?
A Vector graphic is made up of lines and curves defined by mathematical descriptions called vectors. Vector graphics are saved and printed in postscript, the language used by high-quality printing devices. You can create and save a vector graphic from software such as Adobe Illustrator in the .eps or .ai format. Vector graphics are resolution-independent—that is, they can be scaled to any size and printed at any resolution without losing detail or clarity. It is highly recommended to use the vector format for logos, as the edges will always appear smooth, regardless of the size of the image.
