File Types and Their Uses (Part 2)

Marketing Tech entrance


Being a Buffalo Printing company for more than a decade, we’ve seen our share of art files – some good, some very bad. When working with a print, video or online designer, you may encounter the need to work with multiple types of files. There are many, but they fit into two categories, bitmap and vector. Once you understand the differences, identifying the files a designer may need from you becomes easy and time is saved. This week’s blog discusses vector files.

Vector Files

Encapsulated PostScript (EPS)
The EPS file is a raw vector file and can be read by any vector editing program. This file is excellent for print but will not work for the web. A vector file can be well described by first de¬scribing a bitmap file. When one zooms in on a bitmap file, one will notice many squares of solid color. Basically, every bitmap file is composed of tiny squares (pixels) that are a solid color. When these tiny squares of color are put together and one stands back to see, they make up the entire image. A vector file on the other hand, is not made up of tiny squares of color. When a vector graphic is zoomed in on, it will never lose its quality. It is always be crisp, while a bitmap will look grainy and jagged when zoomed in on.

Adobe Illustrator (AI)
An AI file is also a vector graphic and like the EPS can be used for print but will not work on the web. Adobe Illustrator is usually used to create logos and graphics for anything. Illustrator can even export its vector images into bitmap images. For this reason, providing the designer with this type of file is very valuable, when it comes to graphics. Also it’s interesting to note that one can convert a bitmap file into a vector too.

When working with a designer, whether print or electronic, knowing and understanding these file types will help you communicate and save you both time. For more information, contact Marketing Tech for a free consultation at or (716) 332-4369.
