I have a Type 5 profile for the 3800 that I can send you to try. PM your e-mail address to me.
This paper is my fiber based gloss paper of choice. Type 5 is warmer than Photo Rag Baryta, but very similar to Silver Rag. However, it is sharper than Silver Rag and IMO, it has a nicer, and a very elegant, surface texture. To me it is reminiscent of a nicely textured matte paper, but with the punch and dynamics of a fiber based gloss paper.
Most of my Type 5 paper is used for colour images, but I've also done glossy black and white Piezography prints using Cone's Selenium MPS inks.
