This paper ensures that finished prints have a distinguishing texture, weight and surface quality which immediately appeals to skilled printers and discriminating collectors. A fibre base print has a touch and feel about it that shouts "hand crafted."Multigrade IV FB fiber paper is designed for use with most enlargers and printers, that is, those fitted with either a tungsten or tungsten halogen light source. It is also suitable for use with cold cathode (cold light) light sources designed for variable contrast papers. Other cold cathode (cold light) and pulsed xenon light sources may give a reduced contrast range.
