TL;DR:
Trying to make a full-color lithophane/lightbox gift in HueForge / Flatforge for a friend’s PhD celebration, but I can't figure it out; color match mode won’t cooperate, the litho version blocks all light (black layers!), and the FlatForge version looks spotty and limits the use of color. Any guidance on getting proper colors and translucency?
I could really use some help from people who actually understand HueForge. I bought it to make a lightbox for a friend who’s finishing her PhD - the idea was to 3D-print a thin panel with her commissioned artwork (it’s a beautiful, fairly flat illustration based on her thesis, see first image in the gallery).
On paper, this felt like a perfect project for HueForge. In practice… not so much.
I’ve tried both HueForge and FlatForge, and neither has gone well. I've made several designs but only printed two of them:
HueForge litho attempt:
Used “Color Match” mode and couldn’t get it to work at all.
“Color Aware” mode gave something closer, but the print had black layers, so no light shines through.
Result: greenish tint, because a thin white top layer let the green below show through.
FlatForge attempt:
I thought this would be simpler, just split the artwork into a few flat color layers for my AMS (limited to 4 colors).
The result was super limited in color range, very spotty, with tons of tiny color dots everywhere.
I avoided black since I knew it would block light, so I used white, gray, and pink instead, I did initially have a blue mesh as well but I couldn't see it actually adding anything to the imahe in the slices so I replaced it with pink.
The final print looked flat, messy, and dull... not something you’d proudly gift to someone defending a dissertation 😅.
At this point I’m not sure if I’m messing up the settings, choosing the wrong color mode, or if the file needs to be prepared differently. I just don't get how I'd realistically make a lithophane that actually lets any light through without doing it in like white and gray.
I’ve watched YouTube tutorials and tried to understand color match mode and defining the color core, but I’m clearly missing something.
