Here is an outline of what happens to your files and documents when support for PostScript ends:
Adobe applications will no longer recognize PostScript Fonts.
That means you can’t create content using Type 1 fonts after January 2023.
More importantly, existing Adobe files utilizing Type 1 fonts created before January 2023 will NOT be editable without replacing the font. When you try, you’ll receive the dreaded “missing font” error, annoying “link” or “re-link” alert, agitating warning triangles, or even blue banners of doom—depending on what program you’re using. Ugh.
Sure, embedded Type 1 data can be placed for display or printing…but editing will set off alarms that require immediate attention (i.e. interrupt your workflow big time).
PDFs with embedded Type 1 fonts will display as expected. Non-embedded fonts will be replaced in two ways: (a.) by a font that ships with Acrobat or is your operating system’s default; or (b.) by Acrobat’s font substitution table and the available fonts on your system. However, when a viewer other than Acrobat is used in a web browser, “Adobe can’t control what will happen.”
