I tried to reupload the full 600 DPI scan but lemmy.world decided to start coughing - though I don't think uploading it at higher quality is worth it, as the 2000px wide version is already pretty representative of the original.
I think the full PNG is already of printable quality. If you really need it in PDF format for some purpose or other, I recommend just grabbing the PNG and converting it. I may see later if I can convert the 600DPI scan to PDF though.
Does PDF actually allow some objects to be invisible on screen but visible on print? Because that'd be cool.
It's 2225. Archaeologists discover yet another long forgotten university library storage facility. Inside, they find stacks of Elsevier journals that have never been opened. They then find puzzling coffee stains that somehow appear to be result of the printing process, and conclude that the cultural significance of these markings was probably lost to the ages.
