Well somebody has got it wrong. As has been said, the instructions and the Q&A at the end in their leaflet specifically exclude washing and even say what has been confirmed by TonyB65, namely that washing is detrimental. It would seem as others have said that it is based on the waterless automatic process and in the Bellini kit the amount of stabiliser used which is much greater, performs what in the "normal" process is wash then stabiliser.
Interesting that the bleach and fix stages are much reduced compared to other C41 processes. I have seen as much as 6 mins 30 secs recommended for bleach and fix respectively. I carefully copied the revised instructions for the Digibase process and adding it up it comes to 24 mins 45 secs which is a very long time for one film.
Will no water and shorter times for bleach and fix be detrimental to the longevity of the film? Well, we may not know until several years or even a decide or two have passed
