6-color lithographic printing process
The American Lithographic Co. (based in NYC) printed most of the T-cards from 1909 - 1917 (except T204's
and T216's). It's founder, Joseph P. Knapp, invented the machinery which perfected the 6-color lithographic
process. The ink colors were applied in the following order......
BLACK
YELLOW
BROWN
BLUE
GREEN
RED
Therefore, 6 passes through the printing press were required. Occasionally, the cardboard was not precisely
aligned in the press track, poor registration resulted (such as your O'Neil card). Quality Control, for the most
part, would reject such a copy. However, many T206's were not rejected.
