IDImposer is software
IDImposer does not know anything about your printing equipment or other production hardware. It is not a ‘front end’ or ‘driver’ for machines that can print, collate, fold, and/or staple. Instead, the job of IDImposer is to help you with imposing a normal “reader spread” document into a “printer spreads” document.
Marks and slugs and bars
IDImposer can produce a number of types of printer marks. But you might find it useful for your workflow to add your own slugs or color bars in one of the sheet margins. The output of IDImposer is just another .indd file, so you can Place PDF or images files with these objects in the Sheet Margins of your imposed document, perhaps on a Master Page.
Your book printing services supplier
Be sure to talk to your print services supplier before and during your planning process for producing your book. It is quite possible that she will want to do the final imposition herself, since the choice of imposition format depends on many things that she probably knows better than you do: the choice of paper, the size of the press and sheets, the folding equipment to be used, the binding process to be used, and so on.
The role of IDImposer
Or, of course, especially for short-run, hand-folded books, as well as booklets, programs, and various school and church publications, the printer may be YOU. That is where IDImposer shines.
IDImposer can also be helpful for producing your own “dummy” impositions, to better communicate your ideas with the printer.
