Counting on chance

"The covers for 'Counting on Chance' were generated solely on press using three of the four process color printing plates (cyan, magenta, and yellow) from the interior of the book, via a method used mostly for preparing the press for printing called "make-ready." By overprinting color, areas of image are built up on the paper by repeatedly passing the sheets through the press ... In the true spirit of 'chance' the exact image of the cover will be generated at random when printing the book and as of this writing can only be imagined. Instructions to consistently rotate some of the sheets prior to feeding them into the press ensures variation within the edition" -- Colophon.
