Camden is based on the types used in Camden's 'Remaines concerning Britaine' published in London in 1638. The object was to avoid the contradiction inherent in most 'distressed' typefaces made to give the effect of the imperfections in old print. This means that apparently worn characters are perfectly repeated throughout a setting. The makeup of the Camden fonts means that, with a little extra keying time, alternate characters may be brought in which overcome this. Also many characters are provided which have 'period identities' such as the long s with ligatures, tied sorts ct, sp and st, swash characters in the italic and the double vv, all of which can add a specific age identity.
