Branding a business invariably involves designing a suitable logo. Naturally, this entails a lot of careful consideration, research and inspiration, because once your logo is in place, it will be the one thing potential clients will recognise you by.
In other words, it needs to be striking - without being gaudy - memorable and easy to recognise and associate with your name and type of business. What's more, you need to be able to make your logo any size imaginable. Why? Because it needs to become part of all your marketing material, from your Website to stationary to the side of your vehicle or building (if so desired).
If you have ever tried to stretch a JPG, BMP or GIF image, you will know that this is not a viable solutions - these formats appear pixelated, or grainy, when stretched. The larger you make the image, the worse it gets. This is where vector graphics come in. Vector graphics, unlike the aforementioned formats, are not based - or made up of - pixel grids.
Instead, they consist of paths defined by start/ end points, angles, curves, points, and so on. There is no room here to go into specific details, but in essence, vector graphics can be stretched to any size you may desire without loosing their sharpness because they are not made up of a specific number of pixels, or dots.
One of the best tools currently available for vector graphics is Adobe Illustrator CS6, but, like most good things, this comes at a hefty price. If your budget is limited, there are, however, also many good free - or at least considerably cheaper - vector graphic creators.
