Some inkjet printers use dye based ink, some use pigment based ink like HP printers, Canon printers, Epson printers.
Both inks will begin to fade over time. Dye ink, generally, is recommended for indoor use on products that will be consumed in less than a year.
If exposed daily to direct sunlight or bright indoor lights, dye inks may start to fade quickly.
Pigment ink has a superior UV resistance and therefore is selected when many years of indoor use or up to two years of outdoor life is required with little fading.
