We use a top quality supplier for printing and frameing - Adoramapix.com -. We chose a high quality Kodak lustre paper because of its quality/durability and usefulness for doing signing pieces.
In the past we printed canvas ourselves and used a quality fine art canvas with archival inks. While canvas worked very well - especially for signature pieces - it required additional steps of coating to enhance and protect the image. This adds to both time and cost that we chose to avoid at this time.
