A giclee print is a high-resolution reproduction done on a special large format printer.  Giclees are printed with archival quality inks onto a variety of substrates such as convas and fine art paper.  The French term "Giclee" literally meaning "spray of ink," is used to describe these prints.  Precision nozzles spray up to a million microscopic droplets per second onto fine art paper.  The giclee printing process provides excellent color accuracy and highly detailed prints. The majority of our giclee paper prints are printed on acid-free fine art archival paper (Somerset Velvet 255/300 gsm) using Epson UltraChrome PRO Ink.The majority of our giclee canvas prints are printed on Urth Gloss canvas (archival certified, OBA-free) using Epson UltraChrome GS3 solvent ink.From the Epson website:Fade Resistance / Print Longevity:UltraChrome PRO, our next-generation pigment ink technology, is independently rated by Wilhelm Research for up to 200 years for color prints and up to 400 years for black-and-white prints.*Ink lightfastness rating based on accelerated testing of prints on specialty media, displayed indoors, under glass.
