What is a Vector file & why is it good for printing?

Modified on Thu, 12 Jan 2023 at 10:03 PM

Vector graphics, unlike traditional raster graphics, use mathematical modelling to be constructed. They do not rely on pixels but rather use points to draw shapes and curves. While printing your garment, we always prefer vector files for printing as their characteristics allow us to print in the high possible quality that we can.

Below is a good illustration of why Vector files are better than raster files for printing.

Raster image: At 100% the image looks almost the same as the vector version (below). Notice that as soon as the image is scaled, the pixels on the edge begin to show and the edges no longer look smooth. 

Vector image: The vector image is created by defining points and curves. When vector graphics are scaled, the edges remain crisp and sharp no matter the size.

While printing your garment, we always prefer vector graphics, as we scale them up for during our print process. If your image is a poor quality raster to begin with, the end result can look something like the image below.

Important: Not all raster graphics can be converted into a vector image, however all vector images can be converted into a raster image. If you do wish to convert your raster image into a vector image, do follow this guide for more help.
