Although 35 styles seems like an overwhelming number, each has been designed with a use in mind.

Book and Regular give subtle choices in text weight, depending on background color, heaviness of inking, and whether the text will be reversed out. Light and Medium are more display-oriented, although Medium is excellent for text that will be reversed out and inked heavily on absorbent paper.

Bold can be matched with Light, Book or Regular for emphasis. Black matches with Medium, and Ultra should only be used for display, as its counterforms are very small.
