Exhibition Fiber Paper is a breakthrough paper, designed exclusively for use with Epson's UltraChrome K3 ink & 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 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 & tonal transition in B&W & the ability to print extraordinary color with the same paper, something that was not possible to do with traditional fiber based papers. Sheet / Roll Size: 64" x 50 ft; Paper / Media Thickness (mil): 12 mil; Paper / Media Color(s): White; Color Family: White.
