ECO 4812 250ml
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 density of the base fog and Dmax on glossy fibre base and RC papers: 0.00 – 0.02 / 2.00 – 2.30 depending on the paper used. You can find the highest Dmax and with it the highest contrast range with full separation of the shadows, if you use one of the usual suspects: Ilford MGW and Galery, MCC, but also cheaper alternatives such as Adox Fine Print Classic.
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 24x30cm paper.
