It’s an old trick. One fellow printers have been subjected to for years. “Since you have to reprint it anyway, can we make some changes and not be charged?” The truth is, NO print job is perfect. There is ALWAYS some flaw. About the most frustrating thing printers deal with is the client who looks for, and finds that flaw, and uses it as a lever to correct their errors at no charge. This lever is used far too frequently.
Today, for the first time in my recollection, a client called and offered to split the cost of a reprint 50/50. Half for their error, and half for ours. Why is this simple and appropriate gesture so rare? It is the kind of behavior that’s rewarded. Clients who “do the right thing” find themselves getting better prices, faster turns, and even better quality work.
