Time to Print the Maps
As a cartographer, I have found many people have questions about how trail maps are made, so I am always more than happy to describe the process. Aside from creating the maps and collecting GPS information on the trails, a big component of the process is the printing itself. Working with large printing facilities, we print our maps on a special synthetic material called Tyvek, and this Tyvek is run through massive six-color offset printing presses like the one above. Each ink color has a separate printing plate, and the sheets of Tyvek run through this machine from right to left to produce our popular trail maps. It’s fascinating watching this machinery at work, so I always enjoy attending these map printings.
Tonight I’ll be in Norwalk, CT concluding a series of presentations at regional REI stores about how maps are made. I hope I have shed some light on this topic for you as well!
