A New Medium for the Production of Vandykes

L. S. Trimble

As the result of Army complaints on the printing quality of Vandykes, or brown line print master negatives, aircraft companies have spent considerable time and effort in expensive tracing heavy-up work. — Lockheed has specified and had prepared a new and different type of Vandyke paper having sufficient latitude and contrast to produce acceptable prints from combination pencil and ink line tracings. The paper carries a slow photographic emulsion, is processed on the standard blueprint machines under normal operating conditions, and can be furnished at the approximate cost of the present Vandyke paper.
