Custom Logo Design Glossary
Objected-oriented (mode): the Draw graphics mode. A set of algorithms describe graphic form in abstract geometrical terms, as object primitives, the most fundamental shapes from which all other shapes are made: lines, curves, and solid or patterned areas.
Oblique type: characters that are slanted to the right; sans serif typefaces often have oblique rather than true italics, which are a separate font.
Offset printing: for high-volume reproduction -- utilizes three rotating drums: a plate cylinder, a blanket cylinder, and an impression cylinder. The printing plate is wrapped around the plate cylinder, inked and dampened. The plate image is transferred, or offset, onto the blanket cylinder. Paper passes between the blanket cylinder and the impression cylinder, and the image is transferred onto the paper.
One-point perspective: An effect created by lengthening or shortening one side of an object to create the impression that the object is receding from view in one direction.
Opaque: The inability to see through an object. If an object is 100% opaque, you cannot see through it. Opacity levels under 100% increase the ability to see through objects.
Origin: The point in the drawing window at which the rulers intersect
Outline: The line that defines the shape of an object
Output resolution: The number of dots per inch (dpi) that an output device, such as an imagesetter or laser printer, produces.
Overexposure: Excessive light in an image that gives it a washed-out appearance
Orphan: in a page layout, the first line of a paragraph separated from the rest of the paragraph by a column or page break. Headings without enough type under them may be considered as orphans; there should be as much type below the heading as the height of the heading itself, including white space.
