How lithographs are made

I once had a box made for a software product, back when software came in shrink wrapped boxes. The first box cost $4000. The second box cost $0.25. After I'd handed over the files to the artist who assembled the files for printing, and had approved the layouts on her screen, she said, "You want to see the press?" I said OK, and was given ear protection. We went into the press room, where a sheet-fed 7-color offset lithography press over 50 feet long was working. They were turning out fine art prints, faster than one per second. When the box business was slow, they shifted over to making art prints on thick stock.

There's something very calming about the lithography.

Most videos don't show all the tedious steps that go into lithography, including hand grinding of stone to remove previously etched image.
