<p>Aesthetically, you’ll find a design with plenty to like: a hi-visibility “Antarctic Survey Orange” front cover and “Polar Night Black” back cover, with a subtle varnish effect featuring a topographic map of Antarctica. The body pages feature our popular dot-graph paper printed in light gray.</p><p>But the real innovation here is the paper. It’s maybe not even fair to call it paper. The whole book is printed on Yupo Synthetic paper, an amazing tearproof and waterproof paper extruded from polypropylene pellets in Chesapeake, Virginia.</p><p>Months of development and testing were required to get these books just right, and we’d like to thank Yupo for their extensive support, as well as the great printers and ink technicians that pitched in to help.</p><p>Note: Synthetic paper is nonporous and does not absorb ink like our conventional papers. Ballpoint pens, pencils, or fine tip Sharpies work best.</p>
