I am having no success when trying to engrave on dark coloured tumblers.

I have tried many different settings on many different materials.  Obviously I have tried selecting black tumbler and I had no luck.

I had reasonable success selecting black ABS and using engraving for text, it comes out quite clean and clear but when trying to do the same with an image, it's very dark and dull and difficult to see.

If anybody knows of any settings  or ideas to try, please help.
