I've been working on this for about 2 hours now and can't figure out how to remove the invisible background. It shows up when I engrave as a light-gray on some lasertile. I'm also trying to darken the name at the top after changing it into gray-scale and then using the tone curve to lighten the image. It need to be somewhat lighter than the original as it shows up quite dark in the circle and it's hard to distinguish the island. Please help a Corel rookie
