Blank map of Ukraine
All 25 oblasts, unlabeled and unfilled. The SVG prints at any size without going fuzzy and opens in any editor. It comes out wider than it is tall, so it prints sideways.
What you are printing
A conic projection centered on Ukraine, so the oblasts keep their shapes instead of leaning the way they do on a world map.
Every oblast 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 oblast on it
The map page lists all 25 oblasts by name, and colors them in the browser if you would rather not print anything.
