A postscript font is a scalable outline font that meets a specific Adobe Software specification. Postscript fonts match the Type 1 fonts that are needed for a PostScript printer. Type 1 is one of over a dozen different types that are part of the Adobe Fonts. Their scalable nature means that regardless of zooming, the font stays sharp and clearly visible. There aren’t any visible jars or cuts, and no aliasing effect is visible the way it would be on a bitmapped font.
