Which is what makes solvent ink prints more durable than aqueous inks. Certain ink manufacturers have different bite based on what solvent carriers they use. The solvents soften the base material and allow the ink pigments to mechanically latch on to the chemically etched surface. May be used to print directly on uncoated vinyl and other media as well as ridged substrates such as Painted/Coated Metal, Foam Board and PVC. 'Eco-Solvent' inks usually contain glycol esters or glycol ether esters and are slower drying. Piezo inkjet printers whose inks use petroleum or a petroleum by-product such as an acetone like carrier liquid.

Solvent: This term is used to describe any ink that is not water-based.

Aqueous technology requires that all materials be properly coated to accept and hold the ink. Various substrates (media) are available, including canvases, banners, metabolized plastic, and cloth. Finished prints must be laminated to protect them if they are to be used outdoors.

Similar in general principle to desktop inkjet printers. Pigment ink is generally duller in color, requiring more inks to achieve wide inks but withstands fading from UV rays. Dye ink is high color, low UV-resistant variety that offers the widest color gamut. Aqueous ink generally comes in two flavors, dye and pigment. The pigment is held in a non-reactive carrier solution that is sometimes water and other times a substitute liquid, including a soy-based liquid used by Kodak. The term water base is a generally accepted misnomer.

Aqueous: Thermal or Piezo inkjet printers using an ink known as aqueous or water-based.

Wide-format printers can be categorized by the type of ink transfer process they employ: Wide-format printers are usually designed for printing onto a roll of print media that feeds incrementally during the print process, rather than onto individual sheets. Wide-format printers usually employ some variant of inkjet or toner-based technology to produce the printed image and are more economical than other print methods such as screen printing for most short-run (low quantity) print projects, depending on print size, run length (quantity of prints per single original), and the type of substrate or print medium. Wide-format printers are used to print banners, posters, trade show graphics, wallpaper, murals, backlit film ( duratrans), vehicle image wraps, electronic circuit schematics, architectural drawings, construction plans, backdrops for theatrical and media sets, and any other large format artwork or signage. Printers with capacities over 100' wide are considered super-wide or grand format. Wide format printers ( large format printers) are generally accepted to be any computer-controlled printing machines (printers) that support a maximum print roll width of between 18' and 100'.
