The edges of books have been decorated for hundreds of years, be it hand gilded, colored with arsenic for beautiful green, and even spray-painted.
Traditionally, book edges were first sanded to create a flat surface before pigment was applied to glair using a burnishing tool. This look became popular again during the hay day of pulp fiction book production in the 1940s. With modern trimmers and the advent of perfect binding, it was much easier to press textblocks together and paint their edges in mass.
Today, the process can be done faster and on a much larger scale with more decorative book edges thanks to advancements in printing and mechanization.
