![]() Raster graphics are primarilly used to store pictures taken with cameras or screenshots. ![]() A bitmap is a grid of individual pixels (points of colour) that collectively compose an image. ![]() This is also the reason why professional graphics always saved logos, icons and other essential graphics as vectors graphics. The vector images are in general more versatile and easier to use in a lot of different settings and have the same quality as heavy raster images. One of the key benefits of vector graphics is that they are quick and easy to resize into both larger and small sizes without losing any quality. The vector files do not need to memorize a lot of pixels they are often not large in a kilobyte, whereas other files such as PNG or JPG can be really heavy in kilobytes due to the many pixels in the image. The file formats that primarily represent vector graphics are SVG, EPS, PDF or AI graphic formats. Most graphic elements are made in vectors formats whereas pictures, in general, are raster graphics. Vector graphics are made with geometric primitives, so it is easier for it to represent structures and line art. Vector graphics are graphics that are defined from lines and polygons based on mathematical formulas. What is the difference between Raster and Vector files? Vector graphics I will, therefore, introduce you to Raster and Vector files, and how resolution influences the file formats. It also means that printing projects can actually be doomed from the start if the printing material does not have the right resolution. When I started working in the printing industry my thoughts were always, can’t we just grab their logo from their site, if they can’t find it? That resulted in a couple of prints that were not as good looking as they should be. Working with print on packaging, and especially when we are making the design one of the things that confuse our customers the most, is what kind of file formats and the resolution of the materials should be in.
