@Jules and @Dia,
I started with a vector that had a gradient fill (black to white). Tried to upload that as is, but Glowforge gave me a warning that they don’t accept vector gradients yet. The warning recommended that I rasterize the vector gradient. Result: an embedded greyscale image in my Illustrator file that still had the gradient. The Glowforge UI interpreted it no problem.
Note: the rasterized image is slightly fuzzy at the edges compared to the original vector. So, when I chose to score the outside edge of the bug to give it more “pop”, the score did not align perfectly. Now I know not to score the outside edge of a raster/bitmap image.
@john.m.gaffney,
Proofgrade veneer comes with 3M double sided tape on the backside. So, I cleaned my computer with denatured alcohol, peeled off the protective layer, aligned the best I could and pressed out all the air bubbles. Done!
