We’ve talked previously in Printips about the need to preflight the files you submit to us. You may remember that one of the things we check during preflight is whether the document is “bindery-worthy”. By this we mean whether the layout of the document you are submitting has been constructed to account for such things as trimming, folding, drilling, or binding. Ultimately your layout must allow for the effects of these functions or the look of the finished piece will be compromised, no matter how well it is printed.
