this a hue forge printed lithophane, that is in a LED Lightbox. I did a 5mm border around the lighophane so it would fit in the lightbox I designed for it.

I used 4 colors for the graphic and then the box and back is printed in Sunlu Black. I added the lithophone as a seperate print profile as that is how I used the 5 colors. I did use a brim on the inside and outside of the frame to keep it stuck to the plate. might not be needed but that is how I did it.

for the lithophane print.
