This is a requirement for a number of reasons, firstly it eliminates any confusion over artwork placement and ultimately prevents time wasted on back and forth amendments, secondly it means we are not liable for any mistakes made setting the artwork, such as spelling or adhering to brand guidelines. However, our design dept are more than happy to set your artwork, but we must charge for this service, no matter how small the job, so that we can spend appropriate time on it to mitigate errors.
