unfortunately the dyes in ink prints, even ilfochrome ones ..
shift over time. i am clueless, admittedly, i don't know if it is the dye
or the media it is put on ... but if they shift on acid free rag ph neutral paper
won't they have trouble in any media ? when i say trouble, i mean in only a few years
the colors shift ... not a hundred years, or NEVER like dye transfer prints, but just a few years.
