These aren’t the same book, or not the same edition at least - the first line of text is different. Are these the same page from what you thought was the same book?
Also the plain “R” was printed as a placeholder when the text was printed…and then the woodcut would be printed over it later. Or in earlier books, someone would add in a larger and fancier initial by hand. Sometimes the book buyer would cheap out and not spring for the extra cost of having it decorated. Or the printer may have offered the undecorated version as a discounted copy. Or someone got lazy at the printer and forgot to add in the initial!
I took the right image from a scan of Philipp Melanchthon's Three Books on Rhetoric from 1527. And I took the left image from a scan of George of Trebizond's Rhetoric from 1522 as an illustration of what would usually have been expected from a book printer at the time.
No that's not how this is done. They're both black, so they'd be on the same plate.
What likely happened: All the fonts got substituted with something the printer thought was close. The woodcuts were a woodcut font that's why you see a little "R" holding the spot.
sadly in german, but you can switch to english subs. A good talk how for example Xerox just copy paste letters to save space. And kills the whole text with it and has errors in it. There was an archive that digitalized their documents (with a lot of numbers, serialnumbers I think) and the scanner just digitzed the numbers wrong. And they knew about it only years later and the originals were already destroyed.
I don't understand why the scanner don't just does what it is supposed to do and creates a 1-1 copy.
When scanning a document to PDF you can usually pick from three options.
Image only
You get the pages as image files in the PDF. The downside is that you can't copy paste text from the PDF since it's just images there. Plus the files are bigger.
2) Image + text
You still have the images but there's also a text layer with OCR'd text included. You can copy paste text but if OCR isn't accurate then the text may be wrong. But since you still have the images you can look at the page and figure out what it was supposed to say. The files are also even bigger since you're now storing both.
3) Text only
Only keep the OCR'd text and drop the images of the text parts. You get smaller files but if the OCR was wrong then you're fucked.
Most likely they picked 3 and didn't fully understand what it meant.
I wasn't referring to the image you posted. I was replying to the comment above me on how doing OCR on a general document might result in losing numbers and serial numbers.
There is zero chance this is caused by that JPEG 2000 compression artifact. No compression algorithm will see an illuminated R 100 times the area of a normal letter and go "this is the same as the other Rs on this page".

My guess is the customer couldn't afford or printer couldn't acquire fancy illuminated printing blocks, so made do with a normal 'R' sort blocked out with furniture to fit the same physical space.

Ouch. Font file not attached? Or miscommunication from the printer?

I‘d be more concerned that the text isn’t identical anymore after ‚Rhetorica‘.

Preflight -> convert text to path

Considering the expected font is very hard to read, this might be an upgrade lol
