The print clock could be classified as a "probabilistic clock," a group that includes the radiometric clock of geologists used to date rocks and molecular clock of biologists used to date species divergences.

The atomic clock used to measure global time to an accuracy of one second in 60 million years is different.

The print clock is a method for dating art prints and old books produced over the centuries.

It is described elsewhere in two technical publications (Hedges, S.

The surface erosion appears to have been from the routine polishing of the plates that occurred before each print run, to remove nicks and corrosion.

The time-dependency in copperplates is probably related to corrosion during storage.

In woodblocks, the deterioration occurred mainly with aging and random cracking of the wood, resulting in line breaks in the prints.

In copperplates, grooves in the metal became thinner as the surface was eroded, resulting in thinner lines in prints.
