You got me on that one. I was using a different scanner for the majority of that specific post. However, the Daredevil "Marvel Age" cover is from my usual scanner and is very crisp (I re-sized it with the same specifications as the rest). That is my ideal scan.

Some other points are a matter of personal style and taste: I like to keep the color of old newsprint as opposed to bleaching it out and I like a typical comic sized page to somewhat fit on a screen without having to scroll too much to view it. My past posts have varied in that regard, though.
