Raster and vector files
In printing world we have many expressions which can stay a bit unclear, such as vector files. When ordering packages with print we always ask our clients to send us vector files (files with .svg .ai .eps or .pdf extensions). Unfortunately sometimes we do get a .pdf file, but inside it a raster file such as .png or .jpg.
This is why today we are writing a short post about vector and raster files to help people understand the background of print packages. We will answer questions such as what is the difference and how to distinguish a raster and vector file. Also we will cover why is vector file so important for print packages.
So let’s get to the basics. Computer graphics are created as raster files and vector files. Rasters are made up of bitmaps – tiny separate squares that all together make up a picture. It is important to remember, that every raster file is created for a specific resolution. It means that if you start changing the picture size, the quality might suffer significantly. Most popular raster files include .tiff .jpeg .jpg .gif and .bmp extensions.
Compared to rasters, vector files are based on mathematical geometric shapes which means they are made out of squares, circles, lines and curves. Thanks to the formulas it is possible to change vector file picture size without losing any quality. This is why vector files are used to create logos and fonts. Most common vector files are with .svg .eps .ai and sometimes .pdf extensions.
Vector files in print
When we are creating package designs for our clients we always ask them to send us a vector file. Why? Because every package has different measurements and that can cause regular raster file logos lose their quality. This means the print on packages might come out blurry or hard to read.
