Universal developer for all paper emulsion types. The developer works very quickly with a development time of around 60 to 75 seconds at 20°C using the normal 1+9 dilution. This dilution, however, is only recommended for processing Resin Coated (RC or PE) papers or for impatient Fibre Based (FB or Baryta) workers. It produces a neutral to warm tone image which is highly dependent upon the particular paper being used; with Cold Tone papers or those with developer accelerators within the paper itself, the tone is neutral to warm with a tendency towards the green. Warm Tone papers have brownish nuances if developed for not longer than 70 seconds. Above this and over 90 seconds the image becomes markedly more green. A light selenium toning afterwards (diluted to 1+50 to 1+200) will remove the greens and make the image tone somewhat cooler and release the deepest blacks.
Due to the very high capacity of the developer the optimal dilution is 1+20 and a developing time of 2 minutes at 20°C is recommended. With greater dilutions increase the developing time.
The working solution is highly stable and keeps in fully filled containers for a number of weeks.
Dilution: 1+9 to 1+25
1 litre concentrate yields between 10 to 26 litres of working solution.
