So after more than a semester ago I finally managed to scan my sun irradiated prints from my Epson 1500W with different ink sets from original Epson Claria dye to 3rd party dye and pigment inks.
How to interpret these pictures:
Each scan contains 4 images: the 2 on the left column are the reference prints, being kept away safely in the dark cupboard in a box. Upper reference print on Netbit Glossy 270 gsm glossy paper, lower reference print on Eposn Semi Gloss 251 gsm paper. The column on the right are the same prints on the same corresponding paper, but after 6 months exposed to sun light.
Scan 1: Epson Claria Photographic ink (OEM)
scan 2: OCP K3 CcMmYk subset pigment ink
scan 3: OCP Claria compatible dye ink
Scan 4: Inkowl Fade resistant Dye ink
scan 5: Coralgraph dye ink
Conclusion: original Epson Claria Photographic ink still rules in terms of fade resistance. As expected pigment ink is very fade resistant. Inkowl is quite good, but still has some fading. OCP Claria compatible dye refill ink is quite disappointing indeed: fading of this ink is just unacceptable.
The strangest surprise in the Coralgraph ink: despite the slight fading the prints after 6 months of fading is remarkedly good.
