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.

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 mor

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.

Type 1 in PDFs arenot wrong and no problem. Only the use in open app file, like InDesign or Illustrator are a problem. Therefore it makes no sense to check PDF. Repair the routine of your program. T1 in PDFs are completely ok.

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

Did you read our ansers above? T1 in PDFs are no problem. Stop validating T1 in PDFs. It makes no sense.

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

1. Can we use Type 1 font in InDesign after Jan'2023?

2. Whether Font missing will show in InDesign if we used type1 font in InDesign file?

3. Can we use Type1 font in Illustrator after Jan'2023?

4. If we use Type 1 font in InDesign file, what will happen?

5.  Exactly When Type 1 font will end of support?

1. As long as you use an older version of InDesign (v2022 or older): Yes.

Read this PostScript Type 1 fonts end of support .

BUT this does NOT - I repeat - does NOT affect Acrobat or PDF.

2. Opening a file in InDesign 2023 and newer all T1 fonts will be shown as missing regardless if they are installed or not.

3. Same as InDesign, depends on the used version.

4. See 2.

5. Read the above mentioned article.

6. Depends on the used InDesign version, not the purchase itself.

7. As already said above, as long as you use/run a version that is capable of using T1 fonts, you will be able to use T1 fonts, in 2023, 2024, 2025 ... Till the end of the hardware you use.

 

Another point: maybe Windows will also end support of T1 fonts.

But I have no idea if or when, at this time all Windows version up the actual v11 (as of 2022-12-19) support T1.

Stephan

Hi Jayesh,

thank you, glad I could help.

But T1 fonts are really outdated (no unicode etc.) and should be replaced by OpenType fonts if possible.

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 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.

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?

Hi, @nilaatwork ,

afaik that happens when your PDF is printed again through the Adobe PDF printer with the default settings, as the default is: convert all TrueType fonts to Type1 fonts.

I am assuming Windows as the used OS.

 

If I am right (your print service provider is handling your PDF/X that way) there is nothing that you can do to stop it.

Only thing you can do is:

Talk to the print service provider about that problem and ask him to change the treating of your PDFs.

If he is willing to change, you're fine.

If not (either not willing or not possible due to old soft-/hardware), you can accept that or you must find another print service provider that is handling ypur PDFs correctly.

 

Regards

Stephan

Thanks so much Stephan for your answer. I cant stop the provider as its global one, so they wont change anything, sad but thrue. The only thing is to go with old standard fonts which are more common and better produced, i think its a combo of bad produced fonts and the printing setting of the provider...
