THE CORPORATE MARK Logo Components The Digium family of logos are the cornerstone of the identity program. Together with the following key design elements, the logo family brings consistency and brand identity to all of our communications. Typeface. Placement. Color. Symbols. Digium identifies itself with these visible tools. Consistency is important in creating a corporate brand. It is important to implement these guidelines to maintain the integrity of the brand and visual recognition of Digium communications. Symbol Logotype The Digium logo consists of two parts: the symbol and the logotype Clear Space Requirements The family of Digium logos must be allowed a clean visual separation from all other elements with which it appears. Therefore, always maintain the minimum amount of open space around the logos. This allows each logo to function effectively without competition from other visual elements. Use the height of the i in Digium as a guide to define the amount of surrounding open space. Size Restrictions Reducing the size of the signature can alter legibility. All logos in the Digium logo family must not be reduced smaller than 1/2 high. There are no maximum restrictions for the logo s final version. Large-scale uses, such as banners, signs, tradeshow graphics, etc. require accurate enlargements. Please refer to the Logo Formats section of these guidelines. 1/2

THE CORPORATE MARK The Asterisk Bubble The term bubble refers to the combination of the speech bubble and the asterisk inside it. Digium is the only company that can use this logo. The symbol alone can be used as a standalone image or a watermark The symbol may be in pieces but the relationship of the asterisk and bubble must always stay the same. The bubble can also be tinted, transparent, and rotated, but not skewed. The bubble may only be orange (PMS 021) or white. The standalone bubble always needs to be used in conjunction with a symbol.

CORRECT USE OF COLOR Color Usage The Digium identity colors have been selected to present Digium as a leader in the IP-PBX market. Corporate Color The full color logo must always appear on a white background and can only feature the color combinations shown below. The logo may also be all black or all white on approved solid color backgrounds as indicated on page 6. The logo is never to appear with any portion of the logo screened back to any ink percentage less than 100%. If Pantone Matching System (PMS) colors are not available, use the process color (CMYK) equivalent. Care must be taken to ensure clean registration and printing. For Internet applications, use the RGB or HEX equivalent.

CORRECT USE OF COLOR Additional Color Combinations The color combinations below are the only approved combinations of logo and background color for the Digium logo. The logos may not be in a solid color other than black and white. Grayscale is permitted when being printed to a copier that has no color printing capabilities. If the logos are reversed to black or white, the entire logo must be all black or all white. All black logo on white, orange, and warm grey. All white logo on black, blue, orange, and warm grey. In certain instances, these color combinations may also be acceptable. 5

INCORRECT LOGO USAGE All logos on the right are incorrect uses of the Digium logo. Do not manipulate any of the Digium logos in any way. The proportions of each logo have been carefully designed. Condensing, expanding, or skewing it would damage its balance and degrade the brand. Do not alter the size relationship between the symbol and the other elements in the logotype. The spacing between the symbol and logotype is fixed. Do not alter the spacing between the two elements. Don t separate the logo s individual components. Do not incorporate a border or other graphic element around the logo. Do not infringe on the logo s open area. Do not reduce the logo smaller than 1\2 tall. Do not rotate the logo. Do not use the logo without the correct Trademark or Registration symbol. The logos should always appear in the proper corporate color. Please refer to the section of this manual on correct use of color. Do not use a logo on a colored background except approved instances. Do not change the logo to a solid color other than black or white. Do not attempt to recreate or redraw the logo. Always use an electronic version of the corporate logos available from corporate marketing. 6

LOGO FORMATS eps An eps is a vector image. This means you can make it as big or as small as you like without compromising print quality. Stationery & Business cards Signs & Billboards Brochures & Flyers Ads Packaging Direct Marketing & Postcard Vehicle Graphics Embroidered & Silk screen jpg, gif, & png A jpeg is perfect for use on the Internet and in e-mail. Since it has a much lower resolution than an eps and cannot be enlarged without losing design detail it is not recommended for printing. A gif is another low resolution file, great for web and computer use. A png is similar to a gif, but offers greater control over transparency, color ranges, and compression. It also inserts well into desktop publishing and presentation software.
