Hello,

However, I added the result of my long work on the use of the DAS for collotype with the use of hydrogen peroxide instead of permanganate which can also serve enthusiasts of other processes.

Hi Michel, can you give some details about your peroxide clearing method? Concentration and clearing time for example.
I tried a very dilute 0,3 %, for single transfer carbon on fixed baryta paper, but that seems not sufficient. Don't higher concentrations introduce risks for the base or pigments?

thanks,

kees
