Images are printed with Epson Stylus Photo R2880 using Epson’s Ultrachrome K3 inks. These inks are pigment-based and highly stable. According to Wilhelm Imaging Research prints made from these inks on archival-grade papers can persist in high quality for up to 100 years (color) or 200 years (black and white).
I am primarily using the following fine-art papers.
Hahnemühle Photo Rag 308
Canson Rag Photographique
Moab Entrada Rag Natural 300
Hahnemühle Photo Rag Pearl
Print sizes larger than A3+, other options and prices are available upon request.
