Yes, always good to watch and we've discussed it in this thread before (or one of my threads anyway). The thing is that it's a 1977 film and the period we're concerned with is 1960 to 1961. I appreciate the comments about what the plant 'used to' be able to handle, but 17 years is a long time in any industry and there may have been even less capability in 1960 than implied in the video. And also, 1960 was the first time the printers had ever been required to produce pence versions alongside the cents copies. They were likely finding their feet - certainly all the many printing inconsistencies that I have documented support that view as they didn't stick to one format for more than five minutes!
The part about having DC and Marvel together on the same pages answers one of our discussion points but only in the context of 1977 capability not 1960. We need a video from then!
For the sake of argument, let's say the 1960's plates could only manage 350k copies before needing to be replaced. According to Comichron, the comics with the price font variations that I have plotted had average paid circulations of around 150k per issue. So they could easily be produced with one plate even with a healthy overprinting. Also, at some point the plates had to be switched anyway to add the pence stripped copy (I love that one chap in the video is smoking a pipe while doing so). So whilst interesting, the video doesn't seem to answer any of our questions. Taking Rawhide Kid #17 again, why does a book with an average paid circulation of 150k have four variations if the plant that allegedly, soley produced it could manage that volume with one plate?
Could it be that whilst the average paid circulation was around 150k, issue 17 was so popular that a further set of printings was requested? Comichron is one of the few sites that explore the history and they don't even have a monthly / issue break down for this period (unless I'm missing it). Sherlock Holmes used to say that once you remove the impossible, what is left must be the truth. So it seems to me, aside of general remembrances and recollections from this period that no one actually knows for sure. So is a reprint not the most obvious explanation for a book with three different cents price fonts?
Let's hope Brittany and the team take up the challenge to find an answer
