Graphic Formats: Part II - Vector File Formats


As I explained in my last post, vector images are created mathematically by using formulas to create an image that can be enlarged or reduced with no loss of image quality. The picture shown illustrates a vector graphic. Even when enlarged, the image keeps smooth edges.

I also explained that your logo should be initially created as a vector image, and you should have a copy of the original file even if you cannot open it. The programs to create vector files, such as Adobe Illustrator, may not be available to you, but at some point you may need to make a change to the file, and most designers can use this file to make those changes.

Common vector file formats and their uses include the following:

  • AI (Adobe Illustrator) – This is the software that most graphic designers use to create your design or illustration (as the name would suggest). This design tool is the easiest to manipulate (should you know what you are doing) and can be used to create the below files.

  • EPS (Encapsulated Post Script) – This file format is used to produce high-resolution graphics for print jobs. It is a universal format that can be opened in any design tool, including those that are not compatible with Adobe design tools. If you are sending your logo to a printing company to get a banner printed, signage, promotional products, etc., this is the file format most preferred by those companies.

  • PDF (Portable Document Format) – These files can be opened with Adobe Acrobat Reader, which is a free software that takes little time to install. In most cases, you already have this program installed on your computer. In order for a PDF to be a vector file, the original vector would need to have been converted to a PDF. Many print shops can use vector PDFs to produce your work.

Next, I will discuss raster file formats and uses. Be sure to subscribe to learn more.
