This practice can be used to evaluate various properties of one-time noncorrectable ribbons on a comparative basis. These properties include write, flake-off, heat stability, bleed-through, offset master erasability, reproduction, unintentional transfer, and general quality, that is, splices, skips, and holes in coating, offset to back of ribbon, and transfer to fingers.
This practice is suitable for comparative service evaluation and research and development. This practice may not be practical for manufacturing control because of time required to run some of the tests.
