Let's show off archival images of the Guardian's printing process! For much of the 20th century, curved metal stereotype plates would be fitted to presses to print the newspaper. The last Guardian to be fully produced using hot metal was published on 12 May 1987. #HBAHMaking 1/3

And here's a closer look at a stereotype plate! In the archive, we still have a lead alloy printing stereoplate for the front page of The Guardian 3 July 1980. #HBAHMaking 2/3

And voilà, here's the paper being printed out! And there you have it, a Guardian paper fresh off the press in the 1980s! (If only it was that easy...) #HBAHMaking 3/3
