Despite these measures, Adobe's scheme was quickly reverse-engineered by other players in the industry. Originally, Adobe kept the details of their hinting scheme undisclosed and used a (simple) encryption scheme to protect Type 1 outlines and hints, which still persists today (although the encryption scheme and key has since been published by Adobe). At the time, the outline fonts were resident only in the printer, and the screen used bitmap fonts as substitutes for outline fonts.Īlthough originally part of PostScript, Type 1 fonts used a simplified set of drawing operations compared to ordinary PostScript (programmatic elements such as loops and variables were removed, much like PDF), but Type 1 fonts added "hints" to help low-resolution rendering. ![]() Type 1 and Type 3 fonts, though introduced by Adobe in 1984 as part of the PostScript page description language, did not see widespread use until March 1985 when the LaserWriter was introduced by Apple Computer as the first laser printer to use the PostScript language. ![]()
