Inkjet printing paper

This is a special paper designed for inkjet printers. It works by coating a standard paper base with a mixture that includes a positively charged polymer and at least one other ingredient like starch, salt, pigment, or water. This coating helps the printed images resist smearing, running, and fading, especially when wet or exposed to light, for both common types of inkjet inks.

Why it matters: Inkjet ink formulations and printer technologies have advanced significantly since 2008, creating new opportunities for optimized paper coatings to achieve superior print durability. Advances in polymer science may also offer new, more effective coating materials.
