I also us this on a Z3100. I love it for black and white, but think that it is an image specific paper for color work. Saturated color looks great, and high key images work really well. I printed a series of illustrations that were bright pastels on a very light background, and the effect of a satin, iridescent color on a matte background makes it quite unique and striking. That said, I tried some sepia toned images on this stock, and more normal, less saturated color images that just looked weird with the intentional gloss differential this paper is designed to produce. This is not a paper that you will be able to understand or appreciate from reading someone's description of it. It is a unique beast.
