This app uses Callas pdfToolbox server as the imposition engine and consequently you have to have that program installed on your Switch server. The app will analyze the incoming files trimbox size and try to fit as many pages on the sheet as possible. You can set the amount of bleed you want around each page slot and you can also set an amount of gap between each slot. If the page size is very small of the job the maximum number of slots is limited to 24. The app only accepts job with a maximum of 2 pages, the idea is to support those small simple jobs of one or two page jobs like leaflets, signs, letterhead and so on. By using Callas pdfToolbox serverx as imposition engine you get an advantage compared to using HP Smartstream and InDesign as imposition engine. This app supports full parallel processes so if you can run 4 concurrent processes this app supports that. Then Callas pdfToolbox server does the job smarter by just positioning the pages on the sheet, there is no rendering of the incoming PDF. Overall this will give you a quick and automated imposing process for those common daily digital print jobs.
