Contents.History and fonts, though introduced by Adobe in 1984 as part of the page description language, did not see widespread use until March 1985 when the first laser printer to use the PostScript language, the, was introduced. Even then, in 1985, the outline fonts were resident only in the printer, and the screen used bitmap fonts as substitutes for outline fonts.Although 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 ), but Type 1 fonts added to help low-resolution rendering. 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). Despite these measures, Adobe's scheme was quickly reverse-engineered by other players in the industry. Adobe nevertheless required anyone working with Type 1 fonts to license their technology.Type 3 fonts allowed for all the sophistication of the PostScript language, but without the standardized approach to hinting (though some companies such as ATF implemented their own proprietary schemes) or an encryption scheme.
Other differences further added to the confusion.The cost of the licensing was considered very high at this time, and Adobe continued to stonewall on more attractive rates. It was this issue that led Apple to design their own system, around 1991. Immediately following the announcement of TrueType, Adobe published ”Adobe type 1 font format”, a detailed specification for the format. Font development tools such as added the ability to create Type 1 fonts. The Type 2 format has since been used as one basis for the modern Format.Technology By using (PS) language, the glyphs are described with (as opposed to the of ), and thus a single set of glyphs can be resized through simple mathematical transformations, which can then be sent to a PostScript-ready. Because the data of Type 1 is a description of the outline of a glyph and not a (i.e. A ), Type 1 fonts are commonly referred to as 'outline fonts,' as opposed to.
For users wanting to preview these typefaces on an electronic display, small versions of a font need extra and to look legible and attractive on screen. This often came in the form of an additional bitmap font of the same typeface, optimized for screen display. Otherwise, in order to preview the Type 1 fonts in typesetting applications, the utility was required.Font type Type 0 Type 0 is a 'composite' font format - as described in the PostScript Language Reference Manual, 2nd Edition.
A composite font is composed of a high-level font that references multiple descendent fonts.Type 1 PostScript Type 1. &:.,.pfm,.afm.:.pfm,.,.inf (Optional files).:.,.:.ofmMac: LWFN (prn/outline-data/Mac-bitmap).

It can support.It was originally a proprietary specification, but Adobe released the specification to third-party font manufacturers provided that all Type 1 fonts adhere to it.Type 1 fonts are natively supported in Mac OS X, and in Windows 2000 and later via the GDI API. (They are not supported in the Windows GDI+, WPF or DirectWrite APIs.)Type 2 Type 2 is a character string format that offers a compact representation of the character description procedures in an outline font file. The format is designed to be used with the Compact Font Format (CFF).
The CFF/Type2 format is the basis for Type 1 OpenType fonts, and is used for embedding fonts in Acrobat 3.0 PDF files (PDF format version 1.2).Type 3 Type 3 font (also known as PostScript Type 3 or PS3, T3 or Adobe Type 3) consists of glyphs defined using the full PostScript language, rather than just a subset. Because of this, a Type 3 font can do some things that Type 1 fonts cannot do, such as specify shading, color, and fill patterns. However, it does not support hinting. Adobe Type Manager did not support Type 3 fonts, and they are not supported as native WYSIWYG fonts on any version of Mac OS or Windows.Type 4 Type 4 is a format that was used to make fonts for printer font cartridges and for permanent storage on a printer's hard disk. The character descriptions are expressed in the Type 1 format. Adobe does not document this proprietary format.Type 5 Type 5 is similar to the Type 4 format but is used for fonts stored in the ROMs of a PostScript printer.

It is also known as CROM font (Compressed ROM font).Types 9, 10, 11 referred them as font types 0, 1, and 2 respectively, documented in Adobe supplements. Types 9, 10, and 11 are fonts for storing Types 1, 3, and 42, respectively.Type 14 Type 14, or the Chameleon font format, is used to represent a large number of fonts in a small amount of storage space such as printer ROM.
The core set of Chameleon fonts consists of one Master Font, and a set of font descriptors that specify how the Master Font is to be adjusted to give the desired set of character shapes for a specific typeface.Adobe does not document the Type 14 format. It was introduced with PostScript 3 in 1997, and de-emphasized in later years as storage became cheaper.Type 32 Type 32 is used for downloading bitmap fonts to PostScript interpreters with version number 2016 or greater. The bitmap characters are transferred directly into the interpreter's font cache, thus saving space in the printer's memory.Type 42 The Type 42 font format is a PostScript wrapper around a font, allowing PostScript-capable printers containing a TrueType rasterizer (which was first implemented in PostScript interpreter version 2010 as an optional feature, later standard) to print TrueType fonts. Support for multibyte CJK TrueType fonts was added in PostScript version 2015. Main article:PostScript glyph data can be embedded in OpenType font files, but OpenType fonts are not limited to using PostScript outlines.
PostScript outlines in OpenType fonts are encoded in the Type2 Compact Font Format (CFF).OpenType conversion When Adobe converted PostScript Type 1 and Type 1 multiple master fonts to OpenType CFF format, they were made based on the last Type 1/MM versions from the Adobe Type Library fonts. In addition to file format change, there are other changes:. All alphabetic fonts had 17 additional characters included: the euro (some had already gotten this in Type 1), litre, estimated, and the 14 Mac 'symbol substitution' characters. Symbol substitution was a scheme used on Mac OS to deal with the fact that the standard 'ISO-Adobe' character set omitted certain characters which were part of the MacRoman character set. When one of these 14 characters was typed in a Type 1 font with standard encoding, both ATM and the printer driver would get a generic glyph in the Times style from the Symbol font.
