Moersch photographic chemicals is a unique chemical line made in Germany created for the fine art printer.
Moersch MT2 Carbon Toner is a direct toner for warm-tone papers with a high content of chloride silver. Neutral and cold-tone emulsions can be toned indirectly.
The image tone is adjustable by altering either dilution or time of toning. Toning for short durations in dilutions of 1+30 and stronger, the process starts with an increase in maximum black. The image tone turns colder. As toning progresses, the initial image tone first changes to a colder brown and then slowly shifts towards warm brown and red brown hues. If you want a continuous brown black image tone, you have to choose a dilution between 1+100 and 1+200.
In a completely filled storage container, the working solution has a shelf life of a couple of weeks for a dilution of 1+10 or a couple of days for a dilution of 1+200. (If you prepare the working solution with distilled water instead of tap water you increase its shelf life significantly.)
