Definitions for "Wiping"
Wiping or junking is an economic move by radio and television companies in which old audiotapes, videotapes and telerecordings (kinescopes), which were extremely expensive in that era, are erased and reused, or destroyed after several uses. It was particularly prevalent during the 1960s and 1970s, but the practice is now much rarer, as costs have come down and as broadcasters have come to understand the economic and cultural value of keeping archive material.
A part of the inking process in intaglio printmaking. To remove surface ink, the printer uses several muslin or tarlatan pads. The wiping motion is circular and the printer may accidentally leave scratches or circular deposits of ink on the plate. A final step uses the palm of the hand or a piece of tissue. See plate tone and retroussage.
