Lead out on all quad commands only
Description:
This command instructs the composition program the ability to add some leading to justify a column on all quad commands (QL, QC, QR, EP and JU).
hen specified:
Usually at the beginning of a page where such vertical justification is required.
When terminated:
With a new allow vertical justification restarting all default parameters.
Cautions:
If the vertical justification is to appear within a tabular job, only EP and MA will be valid to allow lead out. Quad commands which are used to end a column (QL, QC, QR and JU) do not allow any leading value to be added.

Add leading points are as follow (classified by their priority level):
– proportionnal lead out points,
– all quad commands (QL, QC, QR, EP and JU),
– between all text lines.

Собственно затырка в этом самом lead out в заголовке и в конце описания. Наши полиграфисты сказали, что, дескать, это не вгонка, а что-то типа "Конец абзаца одновременно с выключкой", но это говорилось на бегу, так что осталась я вся в глубоких сомнениях...

Заранее всем спасибо!
