I know that you can buy such cutters that will shop the page into business card sheets -- i've seen them being used for just this kind of application. But i'm not familiar with the brands and models. I don't think they do the collating, but you can set up Flipbook printer to print books in an order that makes it easy to cut a bunch of pages and just stack the sub-stacks, which should make it easy.
Please remember that the current licensing for Flipbook Printer forbids its commercial use without my explicit permission.
I have actually been discussing recently with people the possibility of selling the exclusive rights for commercial use of flipbook printer.
I get inquiries on a fairly regular basis by event coordinators and photographers about licensing it for commercial use, and I'm simply not in a good position to manage such licensing. Others have expressed an interest in using it for larger volume promotional printings.
In short, I think the time has come for me to sell the commercial rights to the program, and I expect to do so by the end of the year.
It's possible (likely?) that whoever purchases the rights will want to license it to people who are interested in using the software for commercial purposes; and I'm happy to try to coordinate these interests while figuring out details of any sales.
I'm interested in finding a good owner for the software who can make good use of it, and ideally develop a longer term relationship that would involve improving the program and coding new related tools.
