Using Xerox Versant 80 to centre a registration on an SRA3 sheet in CWS5 we use image shift e.g. Y .5 front and Y -.5 back if the page was 1mm out in rego. This works fine for pages that we have imposed in Impose, however if we do an imposition in InDesign and the rego is out front and back by 1mm we cannot use the above, instead we can only shift the image on one side. Which means technically the image is not centered on the sheet. Does anyone else have this problem?
