True fonts are font types that were developed by type designers to serve particular emphasis to text. These fonts add visual energy to text through the use of weight, angle, and width. Font families use the basic styles of roman or upright, bold, italic, and bold italic. The font designer, plans each letter to be able to interact with another letter is a visually pleasing manner.
Faux fonts are computer-generated fonts. A bold font is usually a mathematically-thickened version of the regular type instead of the planned bold which a type designer creates independent of the regular fonts. The faux font doesn’t have the visual impact of true fonts when viewing text created from faux fonts.
