It’s worth noting that pure PPI isn’t a good predictor of being able to render pre-digital designs well. Hermann Zapf’s Optima is the classic example of this. It was one of the first Type 1 fonts released from Adobe/Linotype back in the 80s and was an immediate disappointment at anything less than 1200ppi because the subtle aspects of the design were lost in the digitization process. A renewed digital recut of the typeface might resolve some of the issues, but the consensus at the time was that 300ppi was nowhere near enough to properly render Optima’s design.
