If you would like to know about the history of desktop publishing, you require to understand about Adobe's PostScript typefaces. PostScript fonts utilized vector graphics so that they could look clear and crisp no matter what size they were, and Apple accredited PostScript fonts for the original LaserWriter printer; together with publishing software like Aldus PageMaker, they made it possible to produce a file that would look exactly the exact same on your computer system screen as it did when you printed it.

The most important PostScript fonts were so-called "Type 1" fonts, which Adobe at first didn't publish a specification for. From the 1980s up until roughly the early 2000s approximately, if you were operating in desktop publishing expertly, you were probably utilizing Type 1 typefaces.

Other companies didn't desire Adobe to have a monopoly on vector-based font styles or desktop publishing, naturally; Apple produced the TrueType format in the early 90s and certified it to Microsoft, which utilized it in Windows 3.1 and later on variations. Adobe and Microsoft later on teamed up on a brand-new font format called OpenType that might replace both TrueType and PostScript Type 1, and by the mid-2000s, it had actually been launched as an open standard and had actually ended up being the predominant typeface format used across the majority of os and software.

For a while after that, apps that had actually supported PostScript Type 1 typefaces continued to support them, with some exceptions (Microsoft Office for Windows dropped support for Type 1 font styles in 2013). But now we're reaching an inflection point; Adobe ended assistance for PostScript Type 1 font styles in January 2023, a number of years after revealing the change. The other day, a Microsoft Office for Mac upgrade deprecated Type 1 typeface assistance for the continuously updated Microsoft 365 variations of Word, Excel, PowerPoint, OneNote, and Outlook for Mac (plus the standalone versions of those apps in Office 2019 and 2021). The LibreOffice suite, otherwise a good way to open ancient Word documents, stopped supporting Type 1 typefaces in the 5.3 release in mid-2022.

If you started using Adobe and Microsoft's productivity apps at some time in the last 10 or 15 years and you've stuck mainly with the default typefaces-- either the ones consisted of with the software application or the ones from Adobe's extensive font library-- it's not too likely that you've been utilizing a Type 1 font inadvertently. For these sort of users, this modification will be effectively undetectable.

But if you install and handle your own fonts and you've been using the exact same ones for a while, it's possible that you created a file in 2022 that you merely won't be able to view as intended in 2023. The modification will also cause problems if you open and deal with decades-old files with any kind of regularity; files that use Type 1 typefaces will start generating lots of "missing out on font style" messages, and the alternative OpenType fonts that apps might try to use instead can present layout concerns. You'll also either require to convert any specialized PostScript Type 1 typeface that you may have spent for in the past or pay for an equivalent OpenType option.

As Adobe states, "many browsers and mobile OSes do not support Type 1 formats," and macOS has recently lost built-in support for PostScript Type 1 fonts, unless you use third-party software and recorded workarounds. Type 1 typefaces can still, however, be installed straight in older variations of macOS. And it's still possible to set up Type 1 typefaces in modern versions of Windows 10 and 11.

Adobe likewise states that PDF and EPS files with Type 1 font styles will continue to render appropriately, as long as those fonts are "placed for screen or printing as graphic elements." That text will not be editable, nevertheless.

If you wish to see what type of font styles you have installed on your system, Windows and macOS will reveal you that information with a little tweaking. In macOS, open the Font Book app and switch to List view and font style formats will be noted under the "Format" column on the right. In Windows 10 or 11, open the tradition Control Panel, select Fonts, switch to Details see using the button in the upper-right corner, right-click the leading row, and inspect the "Font Type" box. PostScript typefaces can also be recognized by their file extension if you can see it, generally either.pfb or.pfm.
