The word Giclee is French for "a spray or jet of liquid". The name was originally applied to fine art prints created on Iris printers in a process invented in the early 1990s but has since come to mean any high quality ink-jet print and is often used in galleries, print shops, and museums. The giclee printing process retains incredible detail and provides better color accuracy than other means of reproduction.
Actual print stability will vary according to media, printed image, display conditions, light intensity, humidity, and atmospheric conditions. Epson does not guarantee longevity of prints, so I can't either! For maximum print life, display all prints under glass or lamination or properly store them. Refer to framing guidelines.
