I use Unicolor print drums to process sheet film. Need to know if anybody has a solution to keep the film from touching when you are doing 4 sheets in an 8X10 drum. The centre spacer is in place so that you can put two sheets on each side but the sheets on the same side of the centre spacer have the tendancy to slide overtop of each other. I have read somewhere in these pages about somebody usi ng erasers!! or such to separate the two sheets. Anybody have any ideas.
