INDEX

	Object	In programming-language methodology, an object is a unit of a program that contains both code and data. It exhibits a behaviour as a unit, and can be thought of as the simulation of a physical object or system.
	Oblique	A slanted type design, following the letter shapes of the roman variation, as opposed to italic, which is also cursive.
	ODA	Office Document Architecture, an interchange format for expressing revisable, structured documents, not intended to be human readable.
	Office typography	The design and printing of documents for everyday business, scientific, professional, and engineering use. Before desktop publishing, a generally haphazard affair.
	Offset printing	Printing method in which an image is developed on one surface and transferred (offset) onto another, and eventually onto the paper.
	Oldstyle typeface	A group of typefaces typified by oblique, bracketed serifs.
	Optical spacing	Positioning of letters so that they are perceived as having equal spaces between them. Exact geometric spacing does not have this property.
	Orphan	A header or the first line of a paragraph that appear as the last line on a page.
	Outline font description	Specification of the shapes of letters by defining their boundaries (to be filled with the ink colour).
	Overleaf	The other side of a sheet printed on both sides, specifically the page in a book after a right hand page.
