The regular run version of Ratchett came with several variations. To the left is the fuzzy mask version. Lower left is an example of painted white markings. And the next one over is an example of a crisp mask version, and the photo next to that one is an example of a crisp mask chalky version.
The crisp mask version is known as 'The Gerhardt Mask'. To read more about how Karen developed this process, please see the Equilith Fall 2001 Issue.
