There are two types of inks used in wide format printing:
Pigmented and Solvent.
Pigmented (or Aqueous) Ink
Pigmented ink is water-based ink. Aqueous ink
generally comes in two flavors, Dye and UV (alternatively
known as pigment). Pigmented inks are made up of tiny,
encapsulated particles that sit on top of the paper. Images
printed with pigmented ink can last 100 years.
Dye
Ink: is high color, low UV-resistant variety that offers
the widest color gamut. It fades quicker. Dye-based inks are
absorbed into a paper’s fibers. Finished prints using dye
inks must be laminated to protect them if they are to be
used outdoors.
UV Ink: is generally duller in
color but withstands fading from UV rays. UV inks are dried
when cured with UV lights. Prints using UV inks can be used
outdoors un-laminated for a limited time. UV inks are
waterproof. Any media material can be used in this
technology. Media type includes Ceramics, glass, metals, and
woods. Polymer made media are best.
Solvent Ink
Solvent ink is not water-based. May be used to print
directly on uncoated vinyl and other media as well as ridged
substrates such as Foam Board and PVC. Solvent prints are
waterproof. Takes longer to dry.
