FP4 Plus

 

 
 

 

 

To avoid drying marks, use a clean squeegee or 

chamois cloth to wipe FP4 Plus film before hanging 

it to dry. Dry FP4 Plus at 30–40ºC/86–104ºF in a 

drying cabinet or at room temperature in a clean 

dust-free area.

 

Generally for most applications modern camera

films are sufficiently hardened at manufacture.

 

Additional hardening from a fixer hardener is not

 

usually needed or recommended for processing in

spiral tanks, dishes/trays, deep tanks, rotary

 

processors, dip and dunk (hanger) machines and

 

short leader card processors, unless the processing

temperature is above 30ºC (86ºF), or poor drying

performance is being experienced. To minimise the

risk of physical damage a fixer hardener may be

 

needed when using a roller transport film

 

processor.

 

 

Store processed negatives in a cool

 

(10–20ºC/50–68ºF), dry place, in the dark.

 
 

Suitable storage sleeves include those made of 

cellulose triacetate, Mylar, paper (pH6.5–7.5) or

inert polyester.

Using a fix hardener will require the recommended

fix and wash times to be extended. Depending on

the film and processing conditions the hardened

 

fix time will be between 4 and 10 minutes and the

subsequent wash time 10–20 minutes in running

 

water.

 

 
 
 
 
 
 

The amount of HYPAM HARDENER that can be

added to the fixer is dependant on the film and

 

process conditions used. In some processors the

 

full amount of hardener cannot be used as the fix

 

and wash times cannot be extended adequately. In

these circumstances we recommend starting with

 

the minimum amount of hardener to have some

 

effect. This is around 3–6 mls of hardener per litre

of working strength HYPAM used. This increases

 

the film hardness slightly but has a negligible effect

on the fix and wash efficiency. When fix and wash

times are restricted the maximum amount of

 

HYPAM HARDENER recommended is 10–20ml of

 

hardener per litre of working strength HYPAM

 

used. This higher amount gives a definite increase

 

to the hardness of the films processed and while

 

fixing and washing efficiency are reduced the films

will be adequately fixed and washed for most

 

purposes.

 

 
 

 

 
 
 
 
 
 
 
 
 
 
 
 
 
 

When fix and wash times can be extended the

maximum amount of HYPAM HARDENER needed

 

to achieve fully hardened films is 1 part to 40

 

parts working strength HYPAM i.e. 24 ml per litre.

 
 
 
 
 
 
 
 
 

Store FP4 Plus in a cool (10–20ºC/50–68ºF), dry 

place in its original packaging.

 

 
 
 

Once exposed, process FP4 Plus as soon as 

practical. Images on exposed but unprocessed film 

will not degrade for up to several months when 

stored as recommended.
