The 44" x 50' of Epson Exhibition Fiber Photo Inkjet Paper features a 12 mil thickness and a gloss finish. This fiber-based photo paper is designed for color as well as black and white prints and features an ISO brightness rating of 111%. Epson Exhibition Fiber Paper is a breakthrough paper, designed exclusively for use with Epson's UltraChrome K3 ink and was developed in collaboration with many of the industry's leading professional photographers to ensure it meets their most discerning requirements. Many who have contributed to the development of Epson Exhibition Fiber Paper have commented that it not only reminds them of revered silver halide papers, but also offers greater creative control due to extraordinary D-Max and tonal transition in B&W and the ability to print extraordinary color with the same paper, something that was not possible to do with traditional fiber based papers.
