In my project I have text with mixed bold and regular fonts. In the project it looks OK, however, when I export it as pdf, there is bold font also where I have just regular.
I don't know how Adobe Express export PDFs, there are plenty of different PDF types. But let's say for the sake of the discussion that the issue could be that: Do Express generate PDF with the fonts embedded or not. When you generate a PDF with a software that lets you choose the kind of settings you want, you can tell the PDF to encapsultae all the fonts in case you want to share it with people who don't own those fonts. It means that they will not have to install those fonts manually in order to read the PDF properly. It makes the PDFs heavier, obviously, but it's the simplest way to ensure full compatibility. Other options include, not embedding anything, which relies on the other user to either have the fonts installed or for them to be replaced by similar ones at system level, or "rasterising" everything, meaning that the PDF is no longer editable, which most people wouldn't want (But sometimes necessary)
It is possible that in your case, PDFs are generated with a "no embeddeding" option. And that you also don't have the bold version of that font installed on your computer.
The thing is, the fix for this will depend on your subscription. If you have a paid subscription for Adobe Express (or a full CC subscription) then that means you have access by default to all the fonts within the Adobe Fonts platform, and more likely the bold version of the font you're using.
You'll have to use the Adobe CC app to update the fonts you're using
One way to be sure is to make a test using the fonts you know you have already installed in your computer: Say Arial and Arial bold, and see if you're able to read the PDF once exported.
One other way would be to go to the Adobe Express page, choose the "edit PDF" quick action
and change the font on your already downloaded PDF. You can also do that in any other software where you can "read" PDFs and edit them (Acrobat, Illustrator, InDesign and others)
Can you tell me the font you uised and your subscription level?
I had a go as well, and it works with the font I used, that why I thought it was more a font issue than anything else, although , of course, I could be wrong.
Font Poppins. It's synced from Adobe Fonts on my system (separately from Adobe Express) Left is Adobe express in Edge, and right is the resulting PDF in Acrobat reader...
Probably I have to clarify my tutorial. You have to at least do "regular, bold, regular". The second regular results than in bold.
And you are right, some fonts do work like Poppins for example. I could not find any default fonts in the font selection but for example Aileron doesn't work:
I also contacted the support about the problem: They said it's a techinical problem and the software developers got the issue in their todo list. They will update a fix as soon as possible. And said as well that this can may take up some time. In the mean time the only way is to export a PNG and "convert" (put this PNG) into a PDF file using: https://helpx.adobe.com/ca/express/using/edit-document.html
Oh I get it, sorry about that Thanks for updating and talking to the people at Adobe, I can see there are some ironing out to do mostly for less used features (all that is to do with print, I found), and I myself found some bugs and posted on the forum so hopefully it will get sorted soon 🤞
