Fair enough it's something we always budget for (both in terms of cost and time) but I realise not everyone has that luxury.
In some cases even if our client has signed off on the
color/pricing/copy on the last round of color proofs or match prints (which our output house pulls from the output film) which are included with the blue lines (an exact match mockup of the final catalog pulled from the same film as matchprints and four-color film that the web printers plate up for the print run) there still can be errors or mistakes that get past everybody and aren't visible until the first tear-sheet comes off the press, that's why we also have someone from our agency and our clients office at the press check to sign off on color and content.
There is a lot of money on the line so we find that we can't proof and qc enough, and we still get mistakes that get all the way through the finished product and then heads roll. Even if we could say the "client signed off on the final proofs", do we really want to risk losing a multi-million dollar account over a $200,000 printing mistake? Usually the agency sucks it up and takes the loss and deals with it "in-house". Brutal but true. Multi-million piece print runs are high stress and can cause all kinds of gray hairs for a production manager/art director...
The most
dangerous errors normally occur when the client wants to go direct to plate (when all the files are digitally preflighted and prepared and posted directly to the printer via ftp after the client has signed off on the last set of color proofs via Fed Ex), the wrong fonts are loaded, or the bleeds aren't pulled correctly or any number of errors can happen.
Sorry for the encyclopedia length post, this is a subject I have lived and breathed and wanna give any future graphic artists the heads up on what can occur in the real world of print design and web printing...
