An effective font is consistent with the general laws of visual perception, it is developed at the detail level. An effective font is restricted to the essentials in terms of form, it remains in the background and act as a tool only. An effctive font consists of uniform elements, it is logically constructed and have a balanced grey-scale. An effective font is a versatile font, it is lucid and legible in all contexts. An effective font is timeless, it outlasts changes to requirements, media and techniques.
