The absence of font table information indicates no OCR scan occurred, because an OCR scan creates a font table and exports it to the PDF file.

If the desired result was to either have the text in the PDF searchable or replace them with computer fonts (in other words, a full OCR process), then this would be the case. But like I said, that wouldn't make sense with a document like this. The software here was used to detect text blocks and enhance accordingly.

And just what software was that?

You do realize that these results have not been replicated in spite of many efforts.

OCR software is made for the purpose of creating the fonts table as the means by which searchable text is created or any other form of text is created for export to another application. Either you have an OCR scan software creating the font table, or you don’t have OCR software OR an OCR scan. To have an OCR scan, a font table nust be created and exported to the PDF, otherwise it is by definition not an OCR scan.
