Every photo is print by Epson UltraChrome K3 Black-Matte. This ink uses high density pigments to produce lifelike images. Epson Ultrachrome K3 ink significantly improves overall gray balance while enhancing mid-tone and highlight detail yielding a smoother tonal range. And by virtually eliminating metamerism and bronzing, both black & white prints can be produced with the look and feel of a traditional photograph. Photo paper used for the print is Canson Rag Photographique 310g. This kind of support is a 100% cotton museum grade white Fine Art and photo paper. The exceptional smooth white tone is achieved during manufacturing by introducing natural minerals to the process. It has been developed to address the need for continued longevity requirements in the Digital Fine Art market. Rag Photographique offers a unique extra smooth surface with a sensual feel. It also provides one of the highest achievable Dmax currently available on the market, making it ideal for fine art photography as well as fine art printmaking.
