Presensitized
Printing plate 7 By Mr. Bob Gumbinner
We
erected a wall on the north side of the B-line and transferred the
stencil finishing operation from the Prospect Ave. school to this
area. In June, 1961, the stencil finishing operation was moved to a
building we rented on Saw Mill River Road. Among the chemists who
worked under my direction there were Simon Chu, Al Taudien, Gene
Golda, Ibert Mellan and several others. Ibert Mellan invented a way
to use the formaldehyde diazodiphenyamine to be used a positive
working plate. He did this by treating the coated negative plate
with a ferricyanide solution. Gene Golda developed the process of
making the formaldehyde diazodiphenylamine condensate. After we
established Cellomer in the ironbound section of Newark, we set up a
building to make this. I designed, selected the equipment and laid
out the plant to make this sensitizer.
