Additional memo from Mr. Gumbinner 9 Paper offset master

 Polychrome hired Robert Techno and his assistant.  They had worked for Remington Rand which had made stencils and direct image paper offset plates.  We tried the stencil coating but it was not as good as we were making.  Teichner made a direct image offset plate using starch carbonate .  This had two coatings.  The first was a urea-formaldehyde  coating which was cured for a day before applying the starch carbonate coating.  Pot-Devin built the two coaters with a direct gas fired tunnel.  To have enough gas we built a small building for the gas reducers.  Half of this building was used as a lab.  Later it was used to make the photo-sensitive coatings.  One of the main usages of this plate was to update telephone directories.
