Just a quick question for anyone with experience of the coloured sandstone, please.
If I print a small object in coloured sandstone, using white lettering on a black background, how small can I print the lettering before the resolution is lost, taking into account the surface texture of the sandstone itself? How small, before the lettering becomes unreadable?
I will print a test piece first, but I thought someone here might have prior experience of this. Many thanks.

First and very important, in the black vs white ("wheat yellow") battle, the black wins, so white letters over black will need thicker lines than black letters over white. A simple pattern of white and black lines, a 0.4 mm thickness starts to become a problem over a flat surface, and becomes mostly black at half that.

That's brilliant, thanks! Not what I wanted to hear, of course, but saves me printing something that evidently wouldn't have worked. Thanks again, cheers!

Try extruding the text upward to isolate the letters. That will make them stand out better. Raise them around 0.2 - 0.5mm, but don't let the height be more than 50% of the width of the feature. You can get clear letters about 6mm tall doing this.
