quality variable contrast black and white paper on
a 255g/m

fibre base. 
MULTIGRADE IV FB Fiber is part of the ILFORD
MULTIGRADE system and is fully compatible with
all existing MULTIGRADE filters and equipment. It
is equally suitable for printing from conventional
negatives and from XP2 SUPER negatives. 
MULTIGRADE IV FB Fiber is available in double
weight (1K) glossy surface and (5K) matt surface.
EXPOSURE
MULTIGRADE IV FB Fiber is designed for use with
all enlargers.
Safelight recommendations 
MULTIGRADE IV FB Fiber can be used with most
common safelights for black and white papers. The
ILFORD safelights are especially recommended as
they generally allow darkrooms to be brighter, but
completely safe, for MULTIGRADE IV FB Fiber and
many black and white papers.
ILFORD safelights are the ILFORD SL1 darkroom
safelight or the ILFORD 902 (light brown) safelight
filter fitted in a darkroom lamp (for example, the
ILFORD DL10 or DL20). A 15W bulb is
recommended with these safelights.
For direct lighting, do not expose the paper to the
safelight for more than 4 minutes, and the distance
between the paper and the safelight should be a
minimum of 1.2m/4ft.
Other safelight filters can be used, for example, 
the Kodak OC and the Agfa-Gevaert G7, or the
Philips PF710 safelamp.
