Section VIII. MAINTENANCE OF COLOR PRESS
The Townsend Model T-51 color press attachment is used in conjunction with the offset process duplicating machine,
and permits the painting of two colors in a single operation. This is achieved by the use of a twin cylinder, roller and
inking system incorporated into the color press to match the same system in the duplicator. An additional plate
containing only the image to appear in the second color is installed in the color press. This image is then transferred to
the paper before duplication of the primary (darker) color image. The twin-color printed paper is then passed from the
duplicating machine to the receding stacker for drying and jogging.
