What is Vector and why do I need a Vector Logo?
If you’ve ever worked with a designer, you’ve probably heard them refer to vector graphics, perhaps in the context of receiving a logo that is in this format. It’s important to understand the distinction of why it's useful and when should it be used?
SO... WHAT THE HECK IS IT?
The most basic way to describe a vector is that it’s a digital image that can be enlarged or shrunk down and the resolution will stay the same. For instance, the logo the size of a business card will have edges just as clear if you enlarged the entire thing to fit on a billboard. That is because, unlike it’s more familiar counterpart, the raster image, vector images don’t use pixels. Instead, it’s a series of mathematical equations that we won’t even bother getting into; just know that the equations help dictate where the lines and curves of the image should be.
AND WHY DO WE USE VECTOR LOGOS? WHAT FILE FORMAT DOES IT USUALLY COME IN? WHEN DO WE USE IT?
Vector logos are used because of the ease in which the image is scaleable; no matter what size, it will never lose quality The file format of vectors are generally kept as .eps, but can also be saved as .ai and .svg files too. It is industry standard to save logos and other brand details (such as graphics and illustrations) as vector files as this allows for more flexibility in where the logo can be used. Having one file that would look great on a letterhead as well as on a giant window display means saving time not having to design to fit either size. Plus, it’s especially useful for print jobs because it can keep its high resolution.
