WORK-and-TURN

When the second side of the sheet is printed with the same plates as the first side, and the same gripper edge is maintained by turning the paper over left-to-right rather than front to back; which helps maintain better register. See also “work-and-tumble” and “sheetwise”. Whether the job involves work-and-turn, work-and-tumble, or sheetwise, depends on how the job was layed-out in the planning stages.
