Logos, for example, are often generated as AI files as they will need to be used in various sizes of media, on everything from business cards to billboards. So now that you know the difference between vector and raster files, let’s tackle the kind of image files you see the most in a print shop.ĪI files are vector files often used by print shops, creatives and graphic designers to produce graphics which may need to be resized without loss of image quality. Unlike a vector file, with a raster file, as you zoom into it, or enlarge it, the image will eventually turn into pixels, lines no longer being lines, but made up of squares and details becoming blurry in appearance.
The downside to this file type is vector files tend to be very large and can eat up memory.Ī raster file is a graphic file with a fixed size, resolution and image quality. These kind of files are preferred by graphic artists and printers as they can resize the images for billboards, banners, vehicle wraps and so one without loss of image quality. This is done via mathematical statements defining certain points where lines begin and end. If you keep zooming into it and you never see the image break up into square blocks or see lines become pixelated, that is a vector file. You can tell whether an image is a vector or not by enlarging into it on your computer screen. Vector files are graphic files that can be resized without loss of resolution or image quality. All image files can be lumped in two categories: vector files and raster files. So here is some help on alleviating some of that confusion.īut first, before we tackle all those letters and abbreviations, let’s clear up something about image files. eps and so on, it’s easy to get confused on what these are and what they do. These files though have all different names and file extensions.
Some files are sent ready for print, other files maybe requiring some tweaking and yet others are components to be assembled into something being made ready to print. Running a print shop, every day we receive files. By Kristofer Russell, Production Manager at RK Black Office
