ILFORD 2000 RT chemicals have been specifically designed for processing ILFORD ILFOSPEED RC DELUXE, MULTIGRADE RC and all resin coated papers in replenishable roller transport processors. ILFORD 2000 RT chemicals can also be used with all fiber base papers such as MULTIGRADE FB in continuous processors. ILFORD 2000 RT developer/replenisher is supplied as a liquid concentrate packaged in 2 1 2 gallon cubitainers. Dilute 1 part concentrate with 4 parts water to make working strength developer and replenisher. Mix thoroughly. ILFORD 2000 RT developer/replenisher is formulated for use at normal or rapid access processing temperatures of 68°F to 95°F (20°C-35°C). Initially set the developer replenishment rate at 7.5ml for each 8x10 inch sheet or 13.5ml/ft 2 of material being processed. This quantity will provide adequate replenishment for most processors. This rate may be adjusted if necessary. The pH of freshly mixed replenisher solution is 10.5+/-0.5. The specific gravity, taken at 68°F, is 1.058+/-0.05.
