See the ‘Processing summary’ for development 

recommendations. 

 

On correctly exposed prints with MULTIGRADE 

developer 1+9, the image will begin to appear 

after 10 seconds. The minimum recommended 

development time for high quality prints is 45 

seconds; after this time there is a more gradual 

image build-up. Overexposed prints developed for 

a minimum of 35 seconds are acceptable for 

those applications where the highest quality is not 

required. 

 

To give greater control during development, and 

for economy, the 1+14 dilution of MULTIGRADE 

developer can be used. 

 

MULTIGRADE IV RC paper can also be processed 

in other high quality dish/tray developers. 

 

See the ‘Processing summary’ for stop bath 

recommendations. 

 

The use of a stop bath is strongly recommended. 

A stop bath stops development immediately, 

reduces the risk of staining and will extend the life 

of the fixer bath. 

 

See the ‘Processing summary’ for fixing 

recommendations. 

 

The use of a hardening fixer is not recommended 

as it reduces washing efficiency. ILFORD RAPID 

FIXER and HYPAM are non-hardening fixers. 

 

There is no benefit in extending fixation beyond 

the recommended time; some loss of print quality 

might be seen when long fixing times are given 

due to image etching. 

 

See the ‘Processing summary’ for washing 

recommendations. 

 

When it is important to obtain a print in the 

shortest possible time, vigorously wash 

MULTIGRADE IV RC paper for 30 seconds in 

running water. 

 

Prolonged immersion in water can cause edge 

penetration and print curl with resin coated 

papers: for this reason, avoid wet times longer 

than 15 minutes. 

 

A final rinse in ILFORD ILFOTOL, diluted 1+200 

with water, will aid even and rapid drying. 

 

Optimum quality results will be obtained with the 

ILFORD series of dryers, for example, the ILFOLAB 

1250RC. 

 

When a dryer for resin coated papers is not 

available, remove surplus water from the prints 

and leave them to dry. At room temperature, prints 

will dry in 10–20 minutes. 

 

Note MULTIGRADE IV RC paper, as with other 

resin coated papers, should not be glazed/ 

ferrotyped or dried on a drum or flatbed glazer, 

as this can cause the polyethylene in the paper to 

stick to the glazing surface.
