Agfa color print sun test. 1/2 in dark storage 1/2 in sun for 6 months.
I am finishing up Edition II of Dye Stability Testing of Color Imaging Media. I always have a hard time with sun tests because I’m in the NE USA and I can only sun test for about 6 months and that is pushing it. It is not like CA with loads of sun. Sometimes the sun does not come out for a few days and it is gloomy. In the winter the sun may not come out for a week! I’ve got almost everything tested except for a 1 year Eastman Kodak Dye Transfer sun test. It has 6 months of sun and will need another 6 months in 2022.
Kodak improved greatly over the years with the color stability of the dyes it used for Dye Transfers. The 1950’s were the worst. By 1980’s – 1990’s they were pretty good. They were not as good as pigment inkjet prints, but there was still a huge difference between the 1950’s. And the yellow dye permanence was greatly improved compared to the 1950s and 1970s.
