For each order we require the customer to give formal 'artwork approval'.  This means that after we send you a digital 'mockup' of your order, you must inspect it for accuracy of text, color, arrangement, and design.  Once you give us this approval, this creates an agreement between us that we will deliver a finished product to you that matches the digital mockup, as reasonably as it can.  Please understand that when it comes to colors, there are differences in monitors and printers, and what you see on your computer monitor may be slightly different than what we see on ours, so there must be some level of tolerance on getting the colors accurate.
