Were the Romans incapable of reproducing the lead-tin-antinomy alloy used to make Gutenberg's type? They clearly had access to all three metals in some form, but apparently not metallic antimony. But Gutenberg didn't have access to metallic antimony, either, so I'm not sure why that's a limitation.

Gutenberg also had to re-engineer the hand press to apply pressure more consistently across the entire press. I'm not sure if that modification was beyond Roman engineering or just something they hadn't need to do because it's an unnecessary frill when you're pressing olives.
