Grayscale range is very small. when engraving test 16-bit colors, the difference is very small. some shades merge. is it possible to make a setting for each Grayscale color? https://4.bp.blogspot.com/-oVHtmF0o0JY/WBt-WXim_UI/AAAAAAAABjE/7IUjAnLQnRE1zhqliIJGXFmo-mSGEGVawCLcB/s400/%25D0%25BC%25D0%25B8%25D1%2588%25D0%25B5%25D0%25BD%25D1%258C%2B%25D1%2581%25D0%25B5%25D1%2580%25D0%25BE%25D0%25B3%25D0%25BE.bmp
