Not possible to define a number of signatures via MAX variable?

Jump to solution

For books we use signatures of varying sizes, from 3 to 7 sheets per signature.

Currently we have a separate Impose node for each of those variants, but I wanted to see if it was possible instead to have just one node for everything, and supply the number of signatures via a MAX variable.

However, it seems to be impossible? In the Impose node the option "Define number of sheets per signature" only accepts fixed number, not a variable.

Exact same problem with the Pressmarks node, which we use to place shifting sequence marks on the 1st page of each signature - the interval in which these marks are placed is varied depending on the number of sheets in a signature, and it is defined in Placement -> Page Selection : Page Intervals, but that too only accepts fixed numbers, so each variant requires a separate node, even when nothing else is different between these nodes.

Is there any way around this, some way to use just one node for both of the abovementioned cases?

Unfortunately,  "Define number of sheets per signature" does not support the use of FFCore variables.

An alternate solution is to use a Route node. Each branch can have a different imposition node using a different  "Define number of sheets per signature" value. The Route node's job characteristics can be defined to use a MAX variable -- see below
