Re: Silver Gelatin emulsion peeling from Cranes Diploma

I did a lot of liquid  light SE1 from Silverprint on several papers  
and even on aluminium sheets (it was a perfect way to bromoil, no  
hardening of the surface) ;
On paper I think the most important thing is to look after the  
temperature of all the bathes ; it must be below/equal to 20 %  
Celsius, otherwise it is a mess.
Alu-sheets is a different story.
Succes,
Henk
