One of my coworkers did his dissertation on photolithography, I grew up in a family printing shop and we followed a remarkably similar process to generate the metal offset plates that were used in the presses. It turns out that the processes are so similar that my colleague and I often frequently remark about it during idle chit-chat. There's pitifully few good explanation videos about the printing version of this process, but here's a quick video (in Chinese, but if you watch the OP's video this one should be easy to follow) https://www.youtube.com/watch?v=KENIyBWNhyk https://www.youtube.com/watch?v=KENIyBWNhyk The process in the printing industry has gotten very refined as well: you can go directly from a digital image file to a plate in one entirely automated step: https://youtu.be/mA8Dnp0rp3Y https://youtu.be/mA8Dnp0rp3Y https://youtu.be/TeJ_STTfBsI https://youtu.be/TeJ_STTfBsI
