INK SET AND INK SYSTEM FOR PRINTING AN IMAGE

摘要

Ink set includes magenta, cyan, yellow inks. Yellow ink has a maximum absorption ?max in the visible region of 0.25 to 0.45 at a wavelength ranging from 387 nm to 397 nm at a 1-in-5000 dilution of yellow ink in deionized water when 4 wt% to 8 wt% of yellow dye is present in yellow ink. Magenta ink has a maximum absorption ?max in the visible region of 0.2 to 0.4 at a wavelength ranging from 528 nm to 538 nm at a 1-in-5000 dilution of magenta ink in deionized water when 4.5 wt% to 9 wt% of magenta dye is present in magenta ink. Cyan ink has a maximum absorption ?max of 0.15 to 0.4 at a wavelength ranging from 606 nm to 617 nm at a 1-in-5000 dilution of cyan ink in deionized water when 3 wt% to 8 wt% of cyan dye is present in cyan ink.
