There's two types of image files: raster and vector. Raster images use pixels, which are thousands of little coloured squares across an area to make recognisable images. The higher pixels an image has, the clearer the image will be, and the better quality prints that can be done with the image. How many pixels an image has is what controls how the image can be scaled. The more pixels an image has, the bigger the print can be scaled without it becoming pixelated.
Vector images are lines between points that create geometrical shapes. The process uses shapes and lines as opposed to pixels, which means that it can be scaled anywhere from the size of a grain of rice to the size of a football field without any loss in quality, as it doesn't have pixellation issues.
We ask our customers to provide us with high quality raster images (preferably anything over 1500 pixels in either dimension) or vector files. Typically, these files will be in the following file formats:
If you are unsure about these files, for businesses, please ask your marketing, web design or graphics team to provide you with any of these raw logo image files.
