As per Adobe’s decision, the upcoming versions of Illustrator® and InDesign® (already in effect for Photoshop® v23) will no longer support designs using Postscript (type 1) text (will be listed as 'missing font' and substituted by the default font).
You can no longer use type 1 fonts in Dynamic Content, Dynamic VDP, Dynamic Marks, etc.
Esko PDF Import will display an error when trying to import a PDF with type 1 text.
Whether you use Esko plug-ins or not, all Illustrator users will have to upgrade their fonts to OpenType. Once the new fonts are installed, Illustrator (and the Esko plug-ins) will automatically use the new fonts. In the meantime, you can stay on an Illustrator version from before CC2023.
Adobe® Acrobat® and PitStop are not affected: Adobe Acrobat will still display PDFs with Type 1 fonts and Enfocus PitStop text editing features will continue to work as before, also on type 1 text.
