It is a relatively simple process to add weights to a typographic script, hindered only by the scale of the work, when the character set is substantial.

The challenge becomes interesting only in the extremes of the family, the very dark styles, and the very light ones. At these extremes designers need to deal with loops and counters, stroke joints and cross-overs, and all sorts of terminals that may not accommodate a dense stroke within the available space, or dilute the distinctive features of the typeform.
