Ilford Multigrade IV FB Fibre Paper - 24x30.5cm, 50 sheets

Fibre-based papers have a paper base and are more archival, offering a distinct weight and feel. They require longer washing and more careful drying. Resin-coated (RC) papers have a plastic layer, making them faster to process and easier to dry flat, but they are generally considered less archival and have a different aesthetic.

Archival permanence requires thorough washing (at least 30-60 minutes in running water, often aided by a hypo clearing agent) to remove all traces of fixer, followed by careful drying and storage in acid-free materials.

Yes, Multigrade papers are designed to be used with filters in the enlarger's light path to control contrast. You can use it with a standard black and white enlarger or a color enlarger with the filtration method.

The paper speed is ISO P500.

Ilford Multigrade IV FB Fibre Paper is compatible with most standard black and white paper developers. Ilford's own Multigrade paper developer is a popular choice, but others like Dektol can also be used effectively.

Store unexposed paper in its original packaging in a cool, dry place away from light, chemicals, and heat sources to maintain its photographic quality.

Ensure thorough washing to remove all residual fixer. Use a print flattening solution before drying, or try drying on screens/racks. Consider dry mounting for critical prints.

Verify that the wash water is circulating adequately and at the correct temperature. Ensure adequate fixing time. Agitate prints consistently throughout the processing baths.

Check your developer for exhaustion, ensure correct dilution and temperature. You may need to increase exposure time or use higher contrast filters during printing if your negative is inherently low contrast.

Always handle fibre-based papers with clean cotton gloves, especially during the wet processing stages. Avoid touching the emulsion surface directly.
