(v13) Work & turn, work & tumble

This page applies to Harlequin v13.1r0 and later; both Harlequin Core and Harlequin MultiRIP.

When WorkTurn is true, the output is suitable for work & turn, work & tumble and perfecting press runs. In all cases a single plate is produced that prints both sides of the press sheet, by printing one side, turning the paper, and then printing the other on the same plate. In a work & turn style, the gripper edge of the sheet remains the same, but the two print runs use opposite side guides on press. In a work & tumble style, and when perfecting, the trailing edge of the sheet in the first print run becomes the gripper edge in the second. Work & tumble is sometimes called work & roll. The term work & flop may also be used, but it can be used to mean either work & turn or work & tumble depending on the speaker.

Whether the output is suitable for work & turn or work & tumble depends both on TurnTopBottom and the physical orientation of the plate through the press.

Note that the different styles (work & turn or work & tumble) place additional requirements on the rest of the configuration, which is normally addressed by using the following guidelines:

Annotation positions are not normally mirrored in the same way as the margins (for example, because color bars are always  on the trailing edge of the sheet). That means that some care must be taken to set up large enough margins on both edges of a sheet if an annotation is only placed on one edge.
