Open type font changed to Type 1 in Export PDF from InDesign

Hi there!

Adobe has announced that from 01-01-2023 all PostScript Type 1 fonts will be obsolete and not be supported anymore.

In InDesign we have typesetted a document with Open Type fonts and create PDF (export option). 

While checking in PDF, all the Open Type fonts which is in InDesign file that are converted to Type 1 Fonts. Why the font type changed? Is this an InDesign bug? You can see in the screenshot that the selected font has this issue.

Regards,

Santhosh

Adobe have not explained this well, but I think the other replies have. You are trying to fix a problem that does not exist. Type 1 fonts INSIDE a PDF will not be a problem. They are good, and will still be good. 

This is why you are finding a problem in InDesign, LaTeX and 3B2; because you have taken Adobe's misleading info and made a problem that does not exist.


This is where it has become confusing... because Type 1 outlines still exist and will continue to exist. This has nothing to do with unicode, number of glyphs or any other such issue, it has to do with how the fonts are PACKAGED. What is being phased out is the way the fonts are saved on disk. Postscript-flavoured OpenType fonts are essentially Type 1 outlines and their respective hinting wrapped into one file along with their metrics, and then compressed (CFF - Compact Font Format). This is more efficient and cross-platform compatible as opposed to the old inefficent and outdated way of having two separate files; one for the outlines (the printer font) and one for the metrics (the screen font). That old structure made sense in the original Mac Systems before OS X, but has been a hassle to keep supporting ever since, in either platform (and Windows support for that structure was not fun from day one). TrueType and TT-flavoured Opentype had already been one file.. the only big addition to that world is the compression.

So, when you use an PS-flavoured OpenType font, whether it's sent to a printer or exported to a PDF, the compressed outlines need to be uncompressed back to the original outlines to be rendered. In the case of embedding a font in a PDF as a subset, only the outlines for the used characters are needed, so they are extracted (uncompressed) from the full font, then re-compressed when the PDF itself is compressed. Those outlines for all intents and purposes are Type 1... THAT is why you see Type 1 listed in a PDF's font properties.

Adobe could simply re-design how they list these fonts in a PDF; perhaps by adding a reference to the original font's source that indicates it came from an OpenType CFF or OpenType TT file.

Type 1 font support is part of the PDF specifications, aka ISO 32000.

See here why it will never been removed (in the best answer from Dov Isaacs): https://community.adobe.com/t5/acrobat-discussions/is-helvetica-a-type-1-font-in-acrobat-and-reader-dc-is-it-being-removed-in-2023/td-p/11885983

    So, to be clear. your PDF (left) is using TrueType OT) versions of the font, but your print vendor is sending you back a proof where the font is converted to Type 1?

    1. Where did you get your fonts?

    2. What program did you create your document in, and how did you create your PDF? e.g. if InDesign, did you proper;ly Export a PDF or did you use

    It seems the printer has done something to cause the issue. Not clear why they would need to convert to Type 1 outlines anyway unless thay have an ancient RIP (over 15-20 years old) that doesn't handle TrueType (this was an issue back then). Can you upload both of these PDFs for someone to look at?

    thats the thing, its loaded from the latest version of Indesign and Adobe Fonts and yes, you see the problem. I used the standard PDFX standard Profiles so I have no clue what to do. I work in the industry since 2004 and I had never such Problems. I need some help to fix this

    Type 1 font support INSIDE PDF is normal, and needed by billions of PDFs. Conversion to type 1 during export is normal and often a good idea. It is not stopping. So, not a problem and not a bug.

      Dear Tech team

      By January 2023, Type 1 font support will be discontinued from Adobe. So unfortunately if we create pdf from InDesign with Type 1 font then how can we validate in pdf. We have Enfocus PitStop server to validate the pdf for Printer related issues. But while converting PDF from InDesign, font shows as Type 1 for Opentype fonts also. So specifically we are unable to set validation in Enfocus PitStop Server for Type 1 used. Same problem will occur for Latex and 3B2 Software. 

       

      So we should have common validation to avoid Type 1 fonts but open type should be allowed. Do we have any idea to validate the Type 1 font in PDF using Enfocus PitStop Server or any idea to validate original Type 1 font in PDF

      I read it. But my question, let us assume

      We have created pdf from InDesign with Type 1 font by Jan'2023. How can we validate it in pdf, is it possible?. 


      You need not to validate it. It is ok. Use your time for important things.

      OpenType Fonts can be packaged TTF or T1 fonts. This is not a problem. They will work without a problem. Only direct T1 fonts will cause problems, but not these fonts. It is ok, do not bother here.

      We are developing a tool for validating the Type1 fonts which is present in the PDF files by mistakenly. As per above mentioned issue our tool will get failure. That means, If a composer uses OpenType fonts but in InDesign file and it comes with Type 1 format during PDF creation. If we see the fonts details in Document properties from Acrobat (ctrl+d) all fonts shows as Type 1 only. Here how we can validate if the Type 1 fonts. Our quality audits reject the PDF files due to Type 1 fonts used in the PDF. Please advise.

      If you want to detect type 1 fonts used in InDesign you need a solution in InDesign. It is impossible to use the PDF files to detect this, because conversion of OpenType to type 1 is normal and desirable. The design of your tool is completely wrong.
