WHAT TYPES OF PAPERS ARE AVAILABLE FOR PHOTO QUALITY INKJET PRINTING, AND HOW DO THEY DIFFER?
Swellable Papers: (Also referred to as Swellable Polymer) As the name implies the ink receiving layers on these papers swell in thickness in the presence of the moisture in the ink, and allow the colorants to be absorbed. They typically have three layers: a protective top layer, a second that anchors the droplets of ink in place, and a third that absorbs other ink components. Due to their relatively large particle size, pigment inks are not usually recommended or compatible with swellable papers. The pigment particles tend to remain on the surface of the paper and the prints never completely dry. Porous Papers: These papers are commonly called instant dry and may also be described as microporous or nanoporous. The technology behind them, and the way they absorb inks by rapid capillary action is quite different to swellable papers. The surface of a porous paper is coated with microscopic particles that create tiny cavities or pores that take up the ink and prevent it from spreading. Thi
