F.ex. in the case of flyers or other smaller print products: You will not print one product for one customer at once, but many at once (e.g. from different customers), that will share a sheet. So, e.g., you print 1000 of everything, aka 1000 sheets. If a customer needs 2000 they get two spots on the sheet. If a customer wants 4000, they get 4 spots. Now, if a customer needs less than 1000, they still need one spot for the 1000. For that customer this still will be way cheaper than doing a separate small series print.
