Blank map of Colombia
All 33 departments, unlabeled and unfilled. The SVG prints at any size without going fuzzy and opens in any editor. It comes out taller than it is wide, so it prints upright.
What you are printing
Mercator, which stretches land the further it sits from the equator. This map straddles the equator, which is where it stretches least.
Every department is a separate shape, so a vector editor can select and fill one without touching the ones around it. Names are in the file as titles rather than as drawn text, which is what keeps the printed sheet blank.
Every department on it
The map page lists all 33 departments by name, and colors them in the browser if you would rather not print anything.
