In the analog world, you have to think about signal-to-noise ratios instead of DPI. Any given copying technique will add some small but nonzero amount of randomness to the output, which destroys some information. The way digital copying gets around this problem is by having predefined signal levels that are farther apart than the vast majority of copying error, and writing a new master every time instead of the analog copy.
