Two bath development to intensify the colours and to increase the densities of the shadows after lith development.
Lith Omega is used as a second bath after lith development to increase the colours and densities of warm tone papers. With a treatment in Lith Omega it is possible to achieve intensive yellow or reddish tones while using relatively short times of development in strong lith working solutions.
Such tonalities normally require excessive exposure in combination with long times of development in highly diluted developer. Treatment in Lith Omega will evoke intensive colours on warm tone paper with a silverchloride emulsion (such as Forte Polywarmtone and Fomatone) – the papers that are already colourful when used in lith alone.
On bromide silver emulsions and mixed emulsions with a high content of bromide silver you will observe little change in terms of colours, only the densities will increase
