Vector graphics are a computer-generated type of graphic in which graphic elements are saved through definitions. For example, a section is defined by means of its beginning and end points, a square by the length of its sides and the reference point of one corner.
This vector description is especially suited for graphics and are also mostly used for print-logos on promotional items and giveaway. As each individual point does not need to be defined as is the case in pixel graphics, the file sizes are considerably smaller. In addition, the size differences are possible without loss of quality to adjust on the size of different promotional products.
The best known and most widely used graphic programs in the creation of vector graphics for print logos for promotional items and giveaway are Adobe Illustrator and Corel Draw.
