Transition
Towards the end of its life hot metal composition in newspapers was kept alive by the proof press. As each page was set and locked up, it was moved on a turtle (a rolling steel table) to the manual proof press where it was hand inked and a single very high quality proof was pulled. This proof could then be photographed and converted to a negative.
Black paper was inserted before the proof was photographed for each of the photos on the final page to create clear windows in the negative. The separately made halftones would be taped into these clear windows on the negative. This negative could then be used to burn the photosensitized printing plate for an offset press. In this way the heavy investment in hot metal typesetting could be adapted to the newer offset technology during a transition period.

Famous quotes containing the word transition:
“When I was going through my transition of being famous, I tried to ask God why was I here? what was my purpose? Surely, it wasn’t just to win three gold medals. There has to be more to this life than that.”
—Wilma Rudolph (1940–1994)
“There is not any present moment that is unconnected with some future one. The life of every man is a continued chain of incidents, each link of which hangs upon the former. The transition from cause to effect, from event to event, is often carried on by secret steps, which our foresight cannot divine, and our sagacity is unable to trace. Evil may at some future period bring forth good; and good may bring forth evil, both equally unexpected.”
—Joseph Addison (1672–1719)
“Some of the taverns on this road, which were particularly dirty, were plainly in a transition state from the camp to the house.”
—Henry David Thoreau (1817–1862)
