When you give the OK to send an order to print this is confirmation that you have checked the artwork/design work and you are completely happy with all the design/artwork's images, wording, contact details, etc after this, production begins.
It's a very important part of the print/design process and it is YOUR responsibility as the customer, to check for any errors prior to printing. Please carefully check everything is right.
Just to clairify...
