I have my doubts about color, but I have seen whole landscapes and other photo images printed on aluminum plates -- maybe using a liquid emulsion. I'm not sure who does it (or exactly how). Monochrome images can be photoengraved via a halftone process which is or was used for making printing plates. If some sort of white plastic would work it might be possible to do an archival inkjet print (even color) and then laminate a clear protective layer over it. I did some photo-etched stuff about forty years ago(!) but could never claim to be up to speed with current technology.
Hopefully somebody here in PBase land may have some detailed current info. It is a nice gesture to memorialize your daughter.
