To put it simply our designers are human and they live and breathe design. Unfortunately the world of design doesn't always cross over into the world of good english - always check spelling and grammar!
If we make a poor design judgement or make a mistake on a design we will take full responsiblity unless you have confirmed the proof and given the go ahead.
We will attempt to spot any obvious errors on your artwork (design, spelling, grammar, etc), but ultimately, it is your responsibility to accept the final proof. We will not be liable for any errors after accepting the proof reads. It is your responsibility to ask for another proof if you find it difficult to read. When we provide you with an email proof, this is an indication of the final result, as colour variation may occur.
If you are supplying your own artwork or bulk text for us to place in to a design then the responsibility is on you to ensure all spelling and grammar is correct.
