Why Grayscale matters
It is not the same as a one-bit dither. Some laser modes vary power with grayscale, while others convert grayscale into binary marks.
Practical check
How to evaluate it
Determine whether the destination will vary laser power from gray values or convert them into binary marks. That choice changes whether a grayscale file is the final signal or only an intermediate image.
