What software are you using? Try laserGRBL or the paid T2laser programs. They allow you to set the lowest power for white setting so the gray scale runs just to marking white up to your highest black setting. I haven't figured out how to upload a image here but go to thingiverse.com , search laser and you will find a grayscale wheel that will help you find the high and low settings. Good luck
