Gallup depends on its digital printing plant to conduct its public opinion polls

This includes sending out shells to a commercial printer for the color work to be produced on an offset press. Then the variable data is printed in-house on black-and-white printers.

Though the in-plant could print both the color background and the variable data on the NexPress, Morock says it's much cheaper to have shells printed outside, and then use the much faster black-and-white printers.
