Hey Miljnor -
In this case, the laser engraved where the image was light in color and it did not engrave where the image was dark. There is a choice. There are 2 check boxes (click on one and the other goes unchecked) One check box is for "cave" and one is for "convex"
Here is what the manual says:
Convex/Cave: Two kinds of mode of the seal, choose the mode needed;
I forget which option I chose, but one engraves the black part of the image and the other choice engraves the white part of an image.
I will test on alum foil later
