Glossary O

Oblique

Oblique is defined as sloped roman edition of a typeface, frequently used in position of a true italic edition.

Old Face

Old Face is modeled on the humanistic miniscule. Old Face typefaces were formerly written with a average thick wide pen and hence displayed small stroke contrast and the triangular serifs.

Some old face examples are garamond, palatino and aldus.

OPI

OPI means that the protocol developed together by Aldus and Linotype-Hell for replacing low-resolution images (OPI image references in layouts) with their creative high-resolution data.

Now OPI is generally used in pure PostScript systems.

Orientation

This process is the way in which type is laid down on an orientation page.

Orientation can be described as portrait (vertical), inverse portrait, landscape (sideways), or inverse landscape (sideways, upside down).
