Kodak Endura real photo paper (Metallic and E surface) is a media  that is exposed with light and then developed in the classic silver halide process used by professional photo labs worldwide. 

True, photographic media is still far superior to the digital printing process which use inks or other press printing processes.  It's the benchmark by which all photo medias are judged.

Kodak Endura photo prints that appear as brilliant after generations as they do when we brought them home has been the goal since in the invention of color films in the 1930s. With the introduction of color negative films and real photo paper in the early 1940s, pictures became widely displayed items in homes, offices, stores, and elsewhere. People expect those photos to last - with Kodak Endura photos and media, photographers know they will.

In This Day and Age - What is a "Real Photograph"?

The word photograph comes from the Greek words phot, or light and graphia, or writing. A real photograph is exposed with light on light sensitive paper. That's right - light. Photons. Some of the smallest particles in the universe. 

In the case of digital photography, the "light" is formed by Light contained in a Laser light or LED head that "floats" over a light sensitive paper on a bed of warm air. The light exposure excites chemicals on the photographic paper by spraying tiny diamond-shaped patterns on the emulsion. These infinitesimally small diamonds overlap five-fold which, mathematically, results in 425 diamond shapes per square inch. It is this concentration of diamonds created from tiny photons that gives a photograph its unique look, color and depth. Ink doesn't come close.
