Wartime Printing

This was news to me.This is from a book printed in 1943. The printer is Simon and Schuster. It seemed to be a part of the general wartime rationing efforts then I read this:

"Prior to the outbreak of the first World War, at least 90% of dyestuffs were obtained from abroad, mainly from Germany. After the outbreak of hostilities this source was no longer available and problems of supply soon arose."

Well that changes things. It was much more specific to printing. More here. Under President Truman, the Graphic Arts Victory Committee even printed the "Guide to Essential Wartime Printing and Lithography." The book is a bit hard to find, but one catalog describes it as follows:

"...printing in the service of rationing, scrap drives, civilian defense, savings bond drives, moral boosting, etc. etc., with tips on how these themes can be worked into conventional product advertising."
