Each step in the process requires a certain number of disposable sheets of paper for make-readies (testing color density, aligning registration, etc.). Plus paper is easy to damage, and while we damage very little of it, we still need to have extras to cover any damaged sheets. All this means that, in order for you to get a guaranteed number of folders, we have to start your order with significantly more paper than the quantity you requested. On top of that, because we’re starting with extra paper, we wind up with more folders than needed, and the extras just get thrown out, making your exact quantity order more costly. Hence the additional fees.
