![]() This means that the characters appear at 72 dpi and have jagged edges.Īdobe Type Manager fixes this problem. When such fonts are reproduced on a non-PostScript printer (sometimes erroneously called a QuickDraw printer) or shown on a computer display, the Mac uses the screen fonts supplied with the PostScript fonts, but totally ignores the real fonts. otf font files.īy itself, the Classic Mac OS doesn’t understand PostScript fonts. ATM Light 4.6 or higher (see below) provides support for PostScript.There are very few Classic Mac OS applications that work with ATSUI.ttc fonts for Windows machines and OpenType. This mechanism, supplied with Mac OS 9.x, allows ATSUI-compatible applications to use other kinds of fonts, such as TrueType. This avoids the need to download any fonts during the printing process.Īpple Type Services for Unicode Imaging (ATSUI) To speed up printing you should try to use the same fonts in your documents. A PostScript printer normally has a range of fonts stored within its ROM, RAM or hard disk drive.This is especially true if the two examples are supplied by a different font manufacturer, each of which is known as a foundry. TrueType and PostScript fonts with the same name can have slightly different character shapes.Ideally, anyone involved in publishing should remove all TrueType fonts (apart from fonts such as Chicago, Geneva and Monaco that are required by the system) and replace them by PostScript versions. TrueType and PostScript fonts can coexist, although confusion can occur with font names when working with DTP applications.These can be used to display characters on a computer screen at low resolution, typically 72 or 96 dpi. Bitmap fonts are obsolete, despite the fact that older TrueType fonts and many PostScript fonts are accompanied by such fonts, which are also known as screen fonts.However, if you have a PostScript printer or need to swap material with DTP professionals you may have to install PostScript fonts. The Classic Mac OS supports bitmap, TrueType and PostScript fonts, but only the TrueType variety are supplied with the system, since these are adequate for most users. Although the Classic Mac OS can handle the same font technologies as found in other computer platforms, the Mac uses its own variations of file formats, which means you often can’t interchange fonts with other operating systems.Both TrueType and PostScript are to be replaced by OpenType, the latest font format.TrueType, often used by consumers, produces perfectly good results, although PostScript is preferred for desktop publishing (DTP), where easy interchange of fonts is of prime importance. Of these, the last can be disregarded, since they can’t be scaled without distortion. Generally speaking, fonts come in OpenType, TrueType, PostScript or bitmap form. ![]()
