HP Vivera Pigment Ink, (HP 91) for the HPZ6100 DesignJet series printers produces vibrant images and tremendous color while improving UV resistance and color stability over previous ink formulations. With the improved color and durability of the HP 91 Vivera Pigmented Ink, imaging professionals no longer need to choose between the high impact color vibrancy traditionally found in dye inks and the typically muted color gamut found in UV pigmented ink. The HP Z6100 ink is water-resistant and is compatible with a wide variety of both indoor and printable materials. Durability is up to 1 year outdoors — without lamination — and up to 200 years indoors under glass.
