Project manager and editor of the book here! Marcin has posted a lot of updates and newsletters about the printing process. It was fairly arduous to get the quality for the print run we did. Marcin hasn't disclosed the total, but you can tell through the Kickstarter campaign it was at least 4,500. Each of the book set’s hardcover volumes comprise 38 large sheets of paper printed on both sides, then 10 for the softcover volume 3, then sheets for the endpapers and covers and slipcase. Each of those sheets takes from an hour or two to much longer with the degree of attention we paid.

We spent about 100 hours on press with the printers across about eight days, sometimes 12 to 14 hours a day in July with 80°Fs and 90°Fs outside (the printing plant is conditioned somewhat for heat and humidity, and sometimes we had to stop printing for the day as it was just too hot).

It was glorious and exhausting. But we were almost at our physical limits for overseeing the print run and our printers were close to their ability to simply house the raw, printed, and then bound materials. This is an intensely physical object to its scale and the number of pieces.
