Starting about the Vietnam War, mathematical calculations and formulae proved that the 3 x 6-inch leaflet was the most accurate for air-dropping on a specific target. During the Korean War, the three-color 5.25 x 8-inch leaflet was used most extensively and considered the “standard.” The daily production of this sized leaflet using paper rolls with two presses and two shifts (16 hours) was 2,400,000 leaflets. Using sheet fed paper the total dropped to 384,000 leaflets. One can see that a lot of production was lost in carrying sheets of paper to and from the presses.

The last military restrictions ended during the Korean War.

Early in the Korean War the military did not have a dedicated artillery leaflet shell. The 105 mm howitzer smoke shell and the British “25 pounder” smoke shell were most suitable to convert to leaflet shells. With the smoke canister removed each shell could hold about 400 4 x 5-inch leaflets. Artillery can disseminate leaflets with great accuracy and is unaffected by weather conditions. They are best used immediately after an artillery bombardment, preferably at dawn or dusk when the enemy can pick up the leaflets without being seen. During the Korean War artillery was the most accurate means of delivery. Between June 1950 and July 1953 the Eighth Army delivered over 100 million leaflets by artillery, with over 15,000 shells a month being fired at the enemy during peak periods.

Recommendations for leaflet topics and campaigns are discussed in written by the International Public Opinion Research Corporation and subsidized by the Operations Research Office (ORO) of the Johns Hopkins University dated 23 July 1951. This 120-page classified report, with a printing of just 150 copies evaluated the Allied leaflet campaign of the first 205 days of the Korean War after interviewing over 2,000 prisoners of war. It is understood that this is an early survey and as the war continued other recommendations might take priority as the needs and desires of the prisoners was better understood. Some of the recommendations are:
