Echoes things my dad has said.
My did has been in the litho printing industry since the 80s. He has watched the industry change over the years and it is very much in a downward spiral. The engineers are all well past retirement age with very little new blood coming into it. At least in the way of properly qualified machine minders and engineers following the closure of litho schools. This decline was seen in places like Malawi, Zimbabwe and Zambia decades ago. It must be said that the litho industry across Southern Africa was heavily influenced by skilled British migrants, and there was also a huge influx of machine minders and engineers from then Rhodesia in the 70s and 80s when the political landscape changed, so the litho industries in these countries are somewhat interconnected.
The health of the litho industry often tracks with the health of the wider economic landscape. When Covid hit, the industry took a beating because people were not printing marketing material or anything that would change hands, plus business in general all but ground to a halt. When the 2008 GFC hit, the industry took a knock as business closed or scaled back on their spending, with printing often seen as something of a luxury. If the economy is in the sh*tter, the litho industry follows it down the drain. When the economy is on the up, everyone is printing marketing material, company magazines, calendars, etc.
Because the litho industries in Malawi, Zimbabwe and Zambia are pretty much cottage industries now, with a severe shortage of skilled minders, engineers, modern equipment and consumables, a lot of government work from those countries as well as corporate work (mines, banks, etc) is sent to South African print shops. My dad specifically has over the years done a lot of printing for the Malawian Ministry of Education, including printing exam papers for them. In his interactions with people from these countries over the years - which includes government officials - he has been asked numerous times what is wrong with South Africans because they don't know how good they had/have it. People from these countries can see the decline in real time and it is following a similar pattern, albeit at a slower pace because South Africa had a higher starting point.
