Abstract:

We previously discussed small caps and the importance of using true-drawn versions rather than computer-generated, “fake” ones. Many of today’s OpenType fonts include true-drawn small caps, making it easier than ever to take advantage of this typographically sophisticated feature, but the OpenType interface in both Adobe® InDesign® CS3 and QuarkXpress® 7 can be a bit confusing.
