The original and still the most archival dye based ink available, Lysonic was first developed for use on Iris ‘Giclee’ printers for the printing of fine art pieces. It quickly became the industry standard ink set for the art reproduction world. The Lysonic ink set has been re-formulated to now be available for use on most 4, 6. 7 and 8 color Epson photo printer models. Independently tested at 65-75 years life under average indoor display conditions, Lysonic is the ideal ink set for the printing of art and fine art photographic images, and produces the depth of color and subtle tones that cannot be achieved with standard pigment inks. Users of Iris Giclee printers who have replaced their machines with Epson wide format equipment can now match the output of their Iris produced prints by using Lysonic.
