3. CURRENT INFORMATION SUMMARY July 2009 CIS 269 Using KODAK EKTACOLOR Digital Developer Replenisher RT in Roller Transport Processors KODAK EKTACOLOR Digital Developer Replenisher RT is designed for use in roller transport processors using Process RA 4 The performance features of this developer are Primarily designed for digitally exposed output media processed in roller transport processors Produces extra high D max for intense blacks with the most significant impact on processed KODAK PROFESSIONAL ENDURA Transparency and Clear Display Materials Formulated for robust performance in processors operating in a wide range of utilizations These features make EKTACOLOR Digital Developer Replenisher RT a recommended alternative to regular EKTACOLOR Developer Replenisher RT in commercial pro lab applications Product Change Kodak is pleased to announce an improved formulation of KODAK EKTACOLOR Digital Developer Replenisher RT This improved formulation features the same robust performance with greatly reduced potential for crystal formation in the concentrates when stored or transported at low temperatures The improved formulation will be available on a stock turnover basis beginning in mid August 2009 There will be a catalog number change for the new formulation of Digital Developer Replenisher RT See the following table for product catalog numbers Eastman Kodak Company 2009 Kodak Current New Pr
4. Developer Replenisher RT Use sufficient developer at a rate where the volume of replenisher used in two weeks is at least equivalent to the developer tank volume To reduce oxidation further turn off the transport drive except during processing Install a standby switch that allows you to turn off the transport drive without shutting down the recirculation pumps and temperature control Note Do not use KODAK EKTACOLOR RA Developer Additive It is not compatible with KODAK EKTACOLOR Digital Developer Replenisher RT Filtration Processing solutions and wash water may contain some insoluble materials If you don t filter out these materials they can stick to the paper tank walls rollers and solution lines and may damage the paper Usually filters with a porosity of 10 to 30 microns are effective for solutions and wash water For incoming water supplies use filters with a porosity of 15 microns You can use the following filter materials with processors that use EKTACOLOR Chemicals e bleached cotton e cellulose with phenolic resin binder e fiber glass with phenolic resin binder polypropylene spun polypropylene e viscose rayon with phenolic resin binder do not use in the developer e activated carbon Polypropylene is the most acceptable filter core material and one of the least expensive This material has no photographic effect but the surfactants used to produce the polypropylene yarns may have an effect on your p

Replenisher RT KODAK EKTACOLOR Digital Developer Replenisher RT is supplied in separate Part A and Part B flexible containers that will make 189 litres 50 gallons of mixed replenisher Table 2 summarizes the instructions for mixing replenisher Start with approximately 132 litres 35 gallons of water at a temperature between 21 and 37 Celsius 70 to 100 Fahrenheit With stirring add the entire contents of Part A then stir for two minutes Follow by adding the entire contents of Part B then add enough water to equal a total volume of 189 litres 50 gallons Stir until completely mixed approximately 5 minutes Avoid vigorous stirring that allows air into the solution and avoid stirring for over 5 minutes to avoid unnecessary oxidation Store the developer replenisher in a tank with a floating lid and a tank cover to reduce evaporation and decomposition An alternative method of mixing solution is to use an automatic mixer that automatically mixes the replenisher and pumps it to a holding tank Carefully calibrate the delivery of the concentrates and the water according to Table 2 Table 2 Preparing Replenisher Solutions Volume per one Litre Component of Replenisher Water 800 mL EKTACOLOR Digital Developer Replenisher RT 100 mL Part A EKTACOLOR Digital Developer Replenisher RT 100 mL Part B Follow the mixer manufacturer s recommendations to accurately set up the mixing routine Following t
