Adobe Ending Support For Type 1 Fonts...

Some Further Information With Regards to Deprecation of Type 1 Fonts:​


Adobe has announced its intention to end support for Type 1 fonts in January 2023. The full announcement may be found at Type 1 Font Announcement. We strongly recommend that any user of Adobe Creative Cloud applications as well as Adobe FrameMaker read this announcement and plan accordingly.

While you can continue using Type 1 fonts until January 2023, we encourage you to explore alternative fonts in the interim so that you can make a smooth transition when support for these fonts is removed.

Some further considerations and clarifications:
  1. Adobe has previously announced deprecation of support for Type 1 fonts in Photoshop in 2021. Microsoft totally eliminated support for Type 1 fonts in Microsoft Office on Windows a number of years ago.

  2. Type 1 fonts are an integral part of the PostScript and PDF specifications . Neither PostScript nor PDF are affected by this announcement. PostScript, Adobe PDF Print Engine, and Adobe Embedded Print Engine-based RIPs/DFEs and printers will by definition continue to support Type 1 fonts.

  3. Adobe PDF-based products including Adobe Acrobat Reader, Adobe Acrobat Standard, Adobe Acrobat Pro, and the Adobe Mobile Readers (iOS and Android) will continue to support the display, printing, and text editing of PDF files using Type 1 fonts. This is required by the ISO PDF specification.

  4. Even with the deprecation of Type 1 font support in applications such as InDesign, Illustrator, and FrameMaker in January 2023, you will still be able to place EPS and PDF content with embedded Type 1 fonts into these application documents and subsequently be able to display, print, and export PDF content from same.

  5. The Adobe Fonts service never has supported Type 1 fonts in any manner whatsoever. Thus, if you are using fonts from Adobe Fonts, you are not affected at all by this announcement!

  6. The announcement applies strictly to new releases beginning in January 2023. It does not affect support for Type 1 fonts in earlier releases. Thus, you can continue to use Type 1 fonts for editing legacy documents after January 2023. Of course, given the continual incompatible operating system updates by Apple for MacOS and increasingly by Microsoft for Windows, the ability to run these older versions may be limited as time goes on. Furthermore, it is possible that Apple and Microsoft may also discontinue support for Type 1 fonts in the future.

  7. The amount of work to replace a Type 1 font with an OpenType font may be considerable, even if the “replacement font” has the same exact name (most don't, by the way) due to the OpenType fonts using Unicode encoding which affects the mapping of symbolic characters. Also note that for Type 1 fonts, small caps, old style figures, swash characters, non-Western Latin characters, etc. were often in different typefaces than the “regular” typeface. In OpenType, all the characters are in one big honk'in typeface.
The bottom line is that we are encouraging users of Adobe products to examine existing source documents (i.e., not PDF or EPS with embedded fonts) for use of Type 1 fonts and make appropriate formatting updates as soon as possible to minimize problems beginning in January 2023.
