This rectangular design has been in use since before clear plastics were available, and in the past has been on white and with double sided scales. Now printed on clear plastic, it has a number of features and is still in service in many countries around the world.
These protractors are digitally printed on the underside of 1.5mm thick plastic to avoid parallax error. They are then laminated with 15 micron Tedlar® to ensure the image is totally waterproof, scratch resistant, and UV stable for many years. They are then laser cut to an accuracy of +/- 0.25 mm.
