Farming etc. 1984-1992
In the 1980's when I made the colour 'Farming' lithographs I believed that the inks were lightfast. Over time some of the inks are proving to be fugitive and, after a lot of exposure to light, some colours are fading. I recommend that you do as I now do and frame all my colour lithographs from that period with UV glass. This is more expensive than ordinary picture glass but it will keep out almost all ultra violet light and should resolve the problem.
