Some serif designs primarily intended for headings rather than body text are not provided with an italic, Engravers and some releases of Cooper Black and Baskerville Old Style being common examples of this. In addition, computer programmes may generate an 'italic' style by simply slanting the regular style if they cannot find an italic or oblique style, though this may look awkward with serif fonts for which an italic is expected. Professional designers normally do not simply tilt fonts to generate obliques but make subtle corrections to correct the distorted curves this introduces. Many sans-serif families have oblique fonts labelled as italic, whether or not they include "true italic" characteristics.
