A client sent the text which was copied and pasted for a flyer design. The client approved the final file for print. The flyer is printed but does have a typo error. Is the designer responsible for not spotting it? Should the designer have to pay?
My opinion in this case is that the designer is not responsible, since it was client-supplied text, and moreover, the client proofed and approved the final file for print.
That said, many cases like this hinge on a couple things:
1) The designer/client agreement beforehand regarding this type of thing (if there was one). If it was explicitly stated that once client gives final approval, all responsibility is placed on the client, there's no questions afterward. I try to put that in writing for all my clients.
2) the relationship with the client. If it's a highly desired client, the designer may want to offer to split the reprint cost to keep client happy. But based on the facts you state, I see no reason why the designer should have to cover the entire cost.
