Digital BW, The Print

I always thought the UT-FS was pure carbon...

However, I did notice that my prints, on photo rag, get a lot warmer
after some weeks or months, and there is some change in the density
too. Even under very moderate and incidental artificial light. The
fresh print looks stunning, but after a while it gets too red.
Is there a way to avoid this?
And is there such a thing as pure carbon ink?
