Oops, I just realized that what you describe may be attributed to the fact that GIMP will display a dark gray/light gray checkerboard to indicate transparent regions. Perhaps you have created your lithograph correctly but misinterpreted this representation of transparency.
You might try creating a new white layer and placing it at the bottom of the layerstack to show the regions where your image is transparent. _______________________________________________ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
