I don't think it would ever work consistently to let the CB dry before removing the tape. You have to remove it when the CB is still soft. I usually remove the tape right after airbrushing. Works well as long as you haven't sprayed such a thick enough layer that it can run.
Taping in general is very tedious and time consuming, especially for large production. I can't imagine doing it in a commercial setting. Molded bonbons are labor intensive enough. No need to kill the margins even further by adding additional steps.
