Alberto Novo uses the Resinotype process which seems to work on a similar principal to the positive/ positive action described by Henk and noticed by others. Resinotype uses a powdered pigment/ rosin mix in applying colour to a gelatine matrix in a similar way that Oil pigment can produce a positive image given certain conditions,( but still something of a mystery, at present). The pigment powder adheres in proportion to the hardened areas of the gel coating after UV exposure THROUGH A POSITIVE.
I have tried it and it is fascinating to be able to build up the contrast and densities by hand.
Testing, testing, testing. HANW Folks.
Cheers. John.
