Postscript Type 1 Fonts and You

RELEASE DATE: January 1, 2023

Adobe no longer supports document authoring with Type 1 fonts. Type 1 fonts, also known as PostScript, PS1, T1, Adobe Type 1, Multiple Master, or MM are a format within the font industry that has been replaced by larger glyph sets.

What does this mean for Gilson customers?

If your print file is built using Type 1 fonts, Adobe software no longer recognizes the fonts. Print-ready PDFs will still function, but if any edits need to be made to the native files, it may take significant rework to replace the fonts and adjust the document due to small differences in the fonts and ligatures, which can result in reflow of text blocks, pages, and tables.

According to the Adobe website, “Type 1 data embedded in file types such as EPS and PDF will be unaffected by this change, as long as they are placed for display or printing as graphic elements. If those files are opened for editing in applications such as Illustrator or Photoshop, they will trigger a “Missing fonts” error.”

Gilson strongly encourages all customers using Adobe Creative Suite to check their files for the use of Type 1 fonts and ensure that all files are built using TrueType or OpenType fonts going forward to avoid delays in production and avoid costs related to rebuilding customer-supplied files.
