stack.Theeffectisthatifallsheetsarelayedouttoptobottomconsecutively,theimpositionedpages
areorderedbycolumn.Iftheimpositionhasonly1row,bothmethodsareidentical.
Comparison of Stack by Column and Cut and Stack with 16 duplex pages in a 2×2 imposition.
Stack by Column
(toptobottom,stackdown,lefttoright)
Cut and Stack

Inrollfedapplications,reversingtheimpositionordercanbeveryimportant,because,whendoneprop-
erly,thiscausestherolloutputbytheprintertohavethefirstpageontheoutsideoftheroll,allowing
therolltostartwiththefirstpage.
Ourexistingoptiontoreversetheorderofimpositioningisreversingtheorderoftheresultingimpos-
itionsheetsbystartingwiththelastsideofthelastsheet,andthengoingbackwards.Thiseffectively
turnsthestackupsidedown.Italsomeansthat,incaseofdupleximpositioning,allbacksidesbecome
frontsidesandviceversa.
TohaveaneffectivewayofreversingaStackbyColumnimpositionthatleavesthe“bycolumn”order
intact,butthatstartsatthelastpagesinthejob,wehaveaddedanewoptiontoreversetheimposition,
thatbasicallyreversestheincomingsheetorderbeforeimpositioning.Theeffectisthatnotonlyisthe
orderoftheimpositionsheetsreversed,buttheorderofthepagesonthesheetisalsoreversed.
