Logo and symbol are companies' graphic identity. You could say they are like their faces, their appearance, and to a good extent, their personality.

They are usually part of a graphic system, which as a whole strengthens and preserves the visual integrity of the brand and its elements, leading consumers to a better and faster recognition of their products or services.

Graphic identity systems are not exclusive to companies; they also apply to products and product lines.

The search for synthesis in the graphic elements that constitute a logo is not merely a fancy obsesion; it fulfills the real need of standing out more efficiently and achieving a longer lasting presence than the competition. However, excess of synthesis can lead to a lack of personality, and therefore a lack of recognition. It is there, in that balance between 'recognition' and 'synthesis' where design intelligence lies.

Take a look at some logo and corporate identity systems examples.
