After more than 20 years experimenting with of various film and paper developers, Wolfgang Moersch brought his definite and according to him, best paper developer to the markt, the ECO 4812 paper developer.
ECO 4812 offers a density of base fog and Dmax on glossy fiber- and RC-based papers between 0.00 – 0.02 and 2.00 – 2.30 depending on the paper used. The highest Dmax and with it the highest contrast range with full separation of the shadows can be reached if you use one the following known paper series: Ilford Multigrade RC V, Fiber Classic, Fomabrom, Adox MCC,...
The normal dilution is 1+14. Development time: 2½ - 3 minutes. If you use the same exposure times in a dilution of 1+10 and develop for only 2 minutes, the contrast will increase.
The stock solution has a shelf life of 4 years. When opened and depending on the filling level in the bottle this reduces to approximately 2 years. The working solution has a shelf life of 8 months if stored in a bottle. The capacity per litre of stock solution is around 400 sheets of 24x30 cm paper.
