Vector graphics are specially coded image files that are created with lines instead of fixed pixels.  This allows the image to be rotated and scaled proportinally. Vector graphics have numerous advantages to them, the most noticeable is that they allow you to shrink, stretch or adjust images in ways that .jpeg, .gif or .bmp files will not allow with distortion.  The previously mentioned formats are made up of pixels or little squares while vectors are “resolution independent”

When enlarging a vector image, it retains its previous clarity – meaning it remains as sharp and clear as the original image.  When trying to enlarge a format such as .jpg, .gif or .bmp – the pixels are enlarged and lose quality making the original image blurry.  Smaller pixels equal better quality images.

While the advantages are noticeable, the disadvantages are just as noticeable.  The main disadvantage of using vector images is that they do not allow you to create a “realistic photo image”.  Vector’s are made up of solid areas of color, which do not show the tones of a realistic photo.

When speaking of computer graphics, vector images are most common due to their flexibility and the fact that the image is scalable without losing any sharpness.

Here are some key characteristics of Vector graphics:
1. scalable
2. resolution independent
3. cartoon-like
4. not suitable for realistic photo images

When creating “print media” take into consideration that a .jpg, .gif or .bmp cannot be enlarged for bigger print jobs after they are made for there original purpose.  For example, if you create a 4×6 event postcard and later need to print a 11×17 poster for the same event, you wouldn’t be able to take the original .jpg and resize it without losing drastic quality.  In this respect, a vector design is unquestionably the best option you would have for printing.
