Vector vs. Raster Graphics

What is the difference between a Vector and Raster (bitmap) image?

Vector graphics use geometrical objects including points, lines, curves, circles or other shapes to form an image. The alternative is bitmap or raster graphics which are a map of bits, i.e. dots or pixels.

Unlike bitmap graphics, vector graphics vector graphics are scalable (i.e. can be expanded) without losing any resolution. So if I double the size of a vector image then it does not lose sharpness or clarity. But if I were to double the size of a bitmap then I will lose sharpness as the individual bits or pixels become more visible.

Vector-based computer graphics are heavily used in industries that need precise designs: web design, CGI, engineering, construction, manufacturing, and science.

What is EcoEnclose looking for?

In order to upload your art file for custom printing, it must be in a vector format - .ai, .eps, .pdf. However, it is possible for a vector file to contain raster images within it. While we can accept and work with these raster images, we prefer vector images because we know it leads to a more precise, higher quality print. If your art file contains raster images, we will flag this as we work with you, and let you know how this may impact your final print (and give you a chance to provide a file with vector images instead). 

Which programs can I use to create Vector files?

Adobe Illustrator and CorelDRAW are considered industry leading editors, and in our experience work well for creating Vector files.
