Ilford 1770504 User Manual

 

The same times and temperatures as for 

development can be used for fixing. The actual 

fixing time, however, is shorter, and 20 seconds is 

ample above 20ºC/68ºF. These recommendations 

are suitable for both replenished and 

MULTIGRADE IV RC 

 

 

MULTIGRADE IV RC paper can be processed in all 

conventional machines for black and white resin 

coated papers. It is not suitable, however, for 

activation type processing. 

 

ILFORD 2000RT developer/replenisher and 

fixer/replenisher are recommended for use with all 

ILFORD black & white processors. 

 

For the ILFOLAB 2150RC table-top processor 

ILFORD 2150XL developer and fixer kits are 

recommended. 

 

This section is a guide to setting up processors for 

ILFORD resin coated papers using ILFORD 2000RT 

developer/replenisher and fixer/replenisher. These 

are diluted 1+4 to make tank or replenisher 

solution. These suggestions are only a guide, and 

the processing cycle should be checked in the 

processor. For further guidance, contact your local 

ILFORD company or distributor. 

 

The preferred temperature range is 20–30ºC/ 

68–86ºF.

These times are for non-replenished systems, with a 

maximum solution life of seven days. They are also 

for replenished systems with a solution life of up to 

three months. The suggested developer

Note If fixing is not complete, then adequate 

washing is impossible. 

Wash for at least 15 seconds at temperatures 

above 5ºC/41ºF. Set the water flow so as to fill 

the wash tank in 4 minutes or less. 

 

Use temperatures up to 85ºC/185ºF. 

 

MULTIGRADE IV RC responds in the same way as 

other resin coated papers to the usual techniques 

of toning, chemical reduction and retouching. It 

can be mounted using the standard techniques for 

resin coated papers. 

 

Store unused MULTIGRADE IV RC paper in a cool, 

dry place in its original packaging. Avoid 

conditions of high temperature and/or high 

humidity. MULTIGRADE IV RC will keep in excellent 

condition for up to two years when stored as 

recommended. 

 

MULTIGRADE IV RC 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 RC, but other protection 

methods can be used including sulphide toning, 

silver image stabilisers and laminating. ILFORD 

ILFOGUARD laminating and encapsulating films 

are recommended. 

 

A wide range of fact sheets is available which describe and 

give guidance on using ILFORD products. Some products in 

this fact sheet might not be available in your country.
