All of the talk of "authentic revivals" like Garamond Premier Pro has me wondering something. Truly authentic typesetting would use zero kerning, wouldn't it? For instance, if you wanted an AW sequence that didn't have a year's worth of space between them, you'd have to use a physically different sort, i.e., a logotype or ligature to make up the space between them.
So if a person wanted to create a truly authentic spacing setup as was used up until our modern time, how would you go about doing so? For instance, Caslon. An authentic Caslon would never have been kerned, so how would you set up a document so that the spacing was authentic, not just the letterforms?
Or, what kind of metrics settings would a type designer build into a typeface to do the same thing?
