MULTIGRADE IV FB Fiber
OPTIMUM PERMANENCE
The standard fixing and washing recommendations
will give excellent print permanence for all
commercial needs. When optimum permanence is
needed, perhaps for archival storage of prints, the
following fixing and washing sequences at
18–24ºC/65–75ºF (including wash water) are
recommended using ILFORD WASHAID. Do not
add a hardener to the fixer. Be careful not to
exceed the capacity of the fixer and not to extend
the fixing time as both these make washing more
difficult.

FINISHING
MULTIGRADE IV FB Fiber responds in the same
way as other fibre base papers to the usual
techniques of toning, chemical reduction and
retouching. It can be mounted using the standard
techniques for fibre base papers. 
STORAGE
Unprocessed paper 
Store unused MULTIGRADE IV FB Fiber paper in a
cool, dry place in its original packaging. Avoid
conditions of high temperature and/or high
humidity. MULTIGRADE IV FB Fiber will keep in
excellent condition for up to two years when stored
as recommended.
Prints 
MULTIGRADE IV FB Fiber prints which have been
processed as recommended in this leaflet will have
a more than adequate storage life for most
purposes. Print life will be shortened, however, in
adverse storage conditions, or if the print is
exposed to oxidising gases. 
It is recommended that prints made for display are
toned to protect them from the oxidising gases that
are found in many environments. Selenium toner is
recommended as it has little effect on the image
colour of MULTIGRADE IV FB Fiber, but other
protection methods can be used including sulphide
toning, silver image stabilisers and laminating.
ILFORD ILFOGUARD laminating and encapsulating
films are recommended.
