| How lithographs are really made.[1]

| 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.

| because they are running very fast and it's "good enough".
|
| Perfect registration is a given for fine art printers.
| Correct and consistent color is the hard part.
