Why does the color vary from paper to paper, even within copies printed in the same press run?
When the press starts, the press operators are monitoring the color and adjusting it as needed. Sometimes, adjusting color to fix one ad may make the other ads look incorrect, so further adjustments are needed. There may be newpapers that appear slightly darker or lighter than other newspapers within the same run. However, once the correct color density has been set, the colors will start to maintain their consistency.
