OK so what are the new papers?

Glossy and Matte are printed on Kodak Edge, and  Lustre is printed on Kodak Supra Endura.  

Specifications, characteristics:

Glossy: coated paper with a very smooth, shiny reflective surface. Glossy finishes have a high-contrast appearance and look slick to the touch when not under glass.  This finish has an excellent dynamic range and color - slightly more "pop" than the matte paper, though less noticeable once framed.  Photos will have a shiny finish, colors will be vibrant, and images will be crisp and sharp.  Get the Spec Sheet.

Matte: matte paper has a very smooth, non-glare surface. Matte finishes have a lower-contrast when printed and are often used to enhance the texture of a print.  Matte prints are fingerprint and smudge resistant, and work very well with Black & White photos.  Much less glare than glossy.  Get the Spec Sheet.

Lustre:  lustre is our premier paper offering,  and is considered a professional-grade paper. Lustre has a slight gloss with a subtle, often pearl-like texture. Lustre paper has deeper color-saturization and higher contrast than matte and is materially 'thicker,' or heavier, than consumer paper.  Get the Spec Sheet.

Longevity:  KODAK Endura (Lustre) and Edge (Glossy, Matte) are 'archive quality' papers, designed to last for generations.  KODAK's tested light-keeping is equivalent to 100+ years before noticeable fading occurs in a typical home display, and over 200 years in dark storage. For this reason, professional photographers still insist on traditional silver halide materials.  Get all the details here.
