1. A method that assesses character-rendering quality, the method comprising:

  • transmitting a test-character set of test characters to a character-rendering device for rendering;

    intercepting digital pixel-based character maps for the test characters of the test-character set, used by the character-rendering device for rendering the test characters, to serve as an input-character set of input characters;

    capturing test characters rendered by the character-rendering device to serve as an output-character set of output characters;

    for each input character ci, generating and storing in a computer-readable memory one or more metrics that reflect differences between the input characters and the output characters; and

    outputting one or more indications of character-rendering quality based on the one or more metrics.
