Professional logos are designed in vector-based programs, like Adobe Illustrator. Vector based images can be scaled by any amount without degradation of the image. This is essential with logo design since it will be used in a vast number of formats and variety of sizes. You want your logo to be look as crisp and clear on your trade show banner as it does on your business card. Your company’s logo may be a work of art, but if it’s not in vector format, you are asking for trouble.
