RE: First Tricolor Gum (on aluminum)
Silk paper on aluminum is an interesting idea indeed. But that's not what I'm after... Noted for future projects tough - thanks! I currently use nails for registration - it's good when it works but having to pierce the plate is disturbing... On the next try, I will put opaque electrical tape on diagonal corners (such as top-top left, and bottom-bottom right / please note that every corner has two registration marks), align the negatives and then punch the tapes. Thay way, there will be exactly aligned holes surrounded with opaque material on every negative - registration by eye (w/o harming the plate) will be very easy then. (I hope...!)

Then the 'normal' gelatine-glyoxal etc. gum treatment. The effect of the alu-shiny-surface through the thin silk-paper is were i am looking for. Registration with a 'steel scratch tool' in line with marks on the plain paper neg. Cheers, Henk
