Your Logo should be as unique as your company and the last thing you need is for someone to duplicate it. Accordingly, one of the simplest ways to insure that your logo remains the "one and only" is to specialize the font. You can specialize your font in two different ways. The first way to specialize a font is by picking and emphasizing a specific letter from the company's name or slogan. It is usually best to emphases the most important letter of the name or slogan because it will convey meaning to the customer. However, choosing the most important letter isn't always the case, you can chose any letter that you feel will add a little spark to the company. Be cautious though, specialized letters can appear harsh to the eye if not placed next to a complimentary letter. The second way to apply specialized font is by taking regular font and then adding detail to it. For example in the Calypso logo, the font has been specialized by adding "waves" to the ‘s' and little tick marks to all the text creating a feeling of motion. By specializing your logos font you are making sure your logo is unique and conveys your companies message.
