Old topic, new life...
You may be right, but if I were working at USPCC, and I saw the first test batch come off the press looking like that, I'd call up the designer, quickly scan and email them a pic of the back, and say "Hey, they came out rather muddy looking, here's a scan, are you sure this is how you want it?" I mean, that should just be common decency and quality control! Because even if some other guy designed them, the cards will have a big "Bicycle" logo on every box, and that means the quality of the cards will reflect on Bicycle much more than Alakazam Magic.
Also, if they didn't ask for a printing proof, this deck should become the poster child for why that is a bad idea...
Let me tell you a story about how contractors work.
A building is being built or renovated. Contractors are hired - plumbers, electricians, etc. The jobs are bid upon by the contractor, lowest bid wins.
Now let's say that this contractor sees a flaw in the plan - a fixture in the wrong place, a missing junction box, whatever. The contractor will do EXACTLY what's stated in the contract - in fact, they're legally obligated to fulfill the contract as written. If there's an error in the plan, it's not their error, it's the error of the property owner who contracted with them. It's up to them whether to inform said owner, but many won't because of the whole process involved - adding a rider to the contract, paying more money, yelling at the drafter, tending to bruised egos, etc.
USPC, when hired to make a deck, is a contractor. They work with what they're given. I'm sure in many cases they try to spot errors, but unless every single employee you have is dedicated to delivering the best work possible, there's a good chance that something like this can slip through. Now you tell me - have you ever seen a workplace (outside of an Apple store) where every single employee, to the last man/woman, is that dedicated?
